Some- times the giving way sensation may be the result of a torn meniscus that may be repaired with a minor operation erectile dysfunction doctor boston . An older erectile dysfunction ring , recreational athlete may function fine with activity modification and the use of a brace erectile dysfunction treatment gurgaon . Every surgical procedure has a risk benefit, and ACL reconstruction is no exception. If the patient can modify activities to avoid pivotal motions, the knee may function well without surgery. The patient pursuing this approach will probably suffer giving way episodes, accompanied by pain and swelling. In the long term, this will cause wearing of the inside of the knee (osteoarthritis). The patient who wants to carry on with vigorous pivoting sports should have an opera- tion to reconstruct the knee. It does not matter whether the ligament is partially or completely torn. If the knee is lax, as can be measured by clinical examination or with the KT-1000 arthrometer, the ACL is not functioning to protect the knee against pivotal motions. The MRI can determine if the ligament is com- pletely torn, but cannot differentiate the degree of laxity. After the initial injury, there is a 50% chance of damage to the menis- cus. In the chronic situation, the incidence of meniscal tear is 75%, and the torn portion of the meniscus usually has to be removed. In the long term, the removal of all, or part of the meniscus, is associ- ated with an increased incidence of osteoarthritis. What Is the Average Time Needed Before the Patient Can Return to Sports After the Surgery? The answer is four to six months, but sometimes, it may take as long as one year to fully return to a pivotal sport. Treatment Options for ACL Injuries How Long Will the Patient Be Out of Work? If the work involves physical activity, it will take three to four months or until your legs are strong enough. Physical therapy is necessary for approximately one to six weeks postoperatively. The therapy goal is to reduce the pain and swelling, regain range of motion, and increase the strength of the muscles. Therapy may have to be modified based on the individual’s progress through the weeks of rehabilitation. The outcome of the ACL reconstruction depends not so much on the type of graft, but on the technique of placing the graft in the correct position, the fixation of the graft, and the postoperative rehabilitation. Because of the minimum harvest site morbidity, the most common graft used in our sports clinic is the hamstring graft. The patellar tendon graft is used for the athlete who wants to return to sports quickly, for example, at three months. The earlier return to activities is based on the faster healing of the bone-to- bone healing of the patellar tendon graft when compared to the tendon- to-bone healing with the hamstring graft. In a recent metaanalysis of the literature com- paring the hamstring and patellar tendon grafts, no significant difference in outcome was found. However, the patellar tendon grafts were a little more stable, and the patient was able to return to the same level of sports 18% more often than those who received the hamstring graft. Synthetic materials are not routinely used to substitute for the ACL because of the higher incidence of failure. These materials are indicated in special situations, such as multiple ligament injuries or some reoperations. The allograft is obtained from a cadaver, so a minimal risk of disease transmission exists.

Two years after receiving his first cash benefits impotence ginseng , Jimmy will receive Medicare erectile dysfunction treatment prostate cancer . He could then apply for a power wheelchair through Medicare but would almost certainly be denied: he does not need it at home erectile dysfunction email newsletter , where he still navigates with his cane. So Jimmy draws dollars from Social Security and Medicare and neither contributes taxes nor builds his retirement pension. He is happy, home with his wife who also doesn’t work: “Arthritis has put a hindrance on my life, but it hasn’t stopped my life. I figure, as long as God can bless me to get up and see another day, hey, I’m ready to go. Jimmy presumably could live decades longer and, if employed, could perhaps improve both his financial standing and sense of contributing. He had worked ever since his hands were big enough to hold a snow shovel. Although Social Security pays disability income, it does not cover assistive technol- 266 inal Thoughts ogy to permit work. Finally, Medicare pays for power wheel- chairs only if people must use them within their homes—not outside, where they might return to work and leave SSDI. Somebody like Jimmy Howard would not need highly sophisticated equipment. Jimmy Howard would need to adapt his house, at a minimum installing a ramp or constructing a spot in his garage to recharge the batteries. Both her legs were amputated because of severe peripheral vascular disease, and she is too weak to propel herself in a manual wheelchair. With- out question, her private health insurer paid for a power wheelchair, and she happily acquired her new wheels. Her elderly husband cannot put the wheelchair into their car, so she can’t take it anywhere. Insurance refused to pay the $1,900 for an automatic car lift, which she and her husband can’t afford. Abbott’s family have pitched in and are buying the car lift on installment. Even though these costs add up, they nevertheless fall far short of Jimmy Howard’s income support or payment for people to run the errands Mrs. Numerous contradictory policies include the following: • reimbursement only for restorative physical therapy, not ther- apy to maintain function or prevent its decline • limited coverage of mobility aids by private, employment- based health insurance (for which employers choose insurance benefits packages that should—in theory—restore mobility so that able employees could return to work and maximum pro- ductivity) • payment for mobility aids but not for the training to show people how to use them daily in their homes and communities Final Thoughts / 267 • no allowance for trial runs with mobility aids to see if they are helpful (people generally abandon incompatible devices, rarely recycling them to someone who could really benefit) • payment for only one assistive technology in a lifetime or over long periods, so people must get equipment anticipating future needs rather than devices appropriate to their current func- tioning • no allowance for what are seen as expensive “extras,” like spe- cial wheelchair cushions to prevent decubitus ulcers, but reim- bursement for surgical treatment when ulcers occur • withdrawal of coverage for home-health services when people get wheelchairs and leave home independently, without con- siderable and taxing effort Policy analysts speak of “the woodwork effect”—once new benefits be- come available, untold numbers emerge from the woodwork, seeking the service. Predicting demand for services when policies change is therefore difficult. If, for example, insurers suddenly relax their policies and pur- chase power wheelchairs, how many requests would arise? Among people reporting major mobility difficulties, al- most 80 percent (an estimated 4. Who knows how many of them would benefit from manual or power wheelchairs? If 10 percent, this translates into roughly 458,500 people; if 5 percent, approximately 229,200 people. With wheel- chairs costing from about $1,500 to over $35,000 for the most technologi- cally sophisticated models, potential costs are substantial, especially for the one-time expense of meeting unfilled needs. Among people with major mobility problems, 11 percent say they need railings at home but do not have them, while just over 13 percent need bathroom modifications, 5 percent need kitchen modifications or automatic or easy-to-open doors, and around 4 percent need stair lifts or elevators, 268 inal Thoughts alerting devices, or accessible parking. Abbott’s doctor didn’t know who to ask for advice, so they turned to me. I e-mailed Julie Internet addresses of prominent wheelchair manufacturers so she could study their offerings. Nowadays, hundreds of Internet sites relate to dis- ability in general, with many specific to impaired mobility and pertinent diseases. If people do not have a Mobility Mart nearby, at least they can browse the Internet without leaving their homes. Gerald Bernadine found not only his bright red scooter on the Internet, but also the automatic scooter lift for his station wagon.

A general principle is that entries are recorded consecutively, and recording sheets are filed in chrono­ logical order. Increased access to records means that we need to write notes in the anticipation that the reader may be the client – so avoid unnecessary jargon and abbrevia­ tions. The emphasis is on unnecessary, as the use of abbreviations can increase the speed of writing notes. Some employers allow abbrevia­ tions to be used if they are standard amongst the team and a glossary is available if clients wish to access their records. Another major obstacle to clarity in manual records is illegible handwriting. Sometimes entries in notes are unreadable, which com­ pletely defeats the purpose of recording them in the first place. Prog­ ress towards computer-held records is one way of dealing with this problem, as typed entries do not present the same challenge in deci­ phering the message. Copies of clinical notes may be required in or­ der to provide clients with access to their health records, when dealing with a complaint, or by a court of law. Entries written in black ink are more legible than blue or other coloured inks when photocopied. This is primarily to ensure that the clinician is able to recall the details and record them as accurately as possible. Second, the most up-to-date information is then available to any health professional accessing the health record of the client. Clinicians must also be aware that evidence for use in court must be from a record that is contemporaneous with the event to which it relates (Quantum Development 2000). The Department of Health recommends recording information as soon as possible after the con­ tact and at least within the same working day. Any delay in recording notes may reduce the credibility of the professional in any complaint. HOW TO RECORD INFORMATION 33 Summary Points ° Information needs to be accurate, complete, relevant and accessible if it is to be of use to the health professional, whether this is a clinician, manager or administrator. It is not meant to be a definitive account, and the reader is advised to refer to the relevant legislation, health service circulars and guidance notes for a full and com­ plete account. Professional bodies and employers also provide standards in relation to health records management. There are four main issues to be considered in the management of health information: 1. Accountability A health record is a document that contains information about the physical or mental health of an identified individual, which has been made by or on behalf of a health professional in connection with the care of that individ­ ual (Data Protection Act 1998). Although the majority of records are pa­ per based (manual records), there are an increasing number of computer-based notes (electronic records). Health information may also be recorded in other ways such as on audio or visual cassette and CD-ROM.

The following sections offer guidance on the type of information to record at each stage of the care pathway iief questionnaire erectile function . However erectile dysfunction zinc supplements , each clinician is reminded to refer to the standards and practices set down by his or her employing or­ ganisation and his or her professional body erectile dysfunction drugs don't work . Setting up a personal health record A personal health record is set up for the client either when a referral is re­ ceived by the service or at the first contact with the client. The Audit Com­ mission (1995), in a study of hospital records, found that there was no common approach to how these records were organised. They suggested that notes have a clear structure that is agreed with the users – that is, the health professionals and the administrative staff. This will help users in identifying the current epi­ sode and the most recent entry. Arranging data into specific sections like assessments, treatment and so on may also help the reader to quickly locate the relevant information. Every clinician has a responsibility to check, update and maintain the client records they are using. Identification details Each health record must contain the personal details that will enable the identification of the client to whom the information pertains. This will usually include the client’s: ° names (at least the first and the last name) ° title (Mr/Miss/Mrs/Dr) ° form of address preferred by the client (for example, first name or title with last name) ° address ° telephone number ° date of birth ° identification number (for example NHS number, social security number, number issued by health provider). Other relevant information would include: ° the name and address of the next of kin/carer/guardian ° preferred form of address for the next of kin/carer/guardian ° name and address of the client’s general practitioner ° details of other professionals in regular contact with the client. Referral stage One of the key pieces of information to note in the health record is the rea­ son why the client is being seen by your service. It is often the case that cli­ ents are referred by another health professional or an associated agency such as social services. In some cases there may be no referring agent, for instance clients who self-refer, or emergency admissions to accident and RECORD KEEPING 47 emergency. You will therefore need to record the circumstances or inci­ dent that has prompted the client’s attendance. Part of the record at this point in the process will include the client’s account of the reason for his or her contact with your service. In some cases it may be appropriate to also make a note about the attitude of the client or the family towards the referral. For example, parents may disagree that an appointment with the clinical psychologist is necessary, but still attend the appointment at the behest of the child’s school. A complete record at the referral stage in the care process will show: ° the name and position of the referrer ° the date of the referral ° the reason for the referral. Key documents to be kept on file: q referral letters/admission forms q reports accompanying referral. Initial assessment Assessment is a process that will involve gathering information through in­ terview, observation, clinical investigations and objective and behavioural tests. The type of information collected will relate to the theoretical ap­ proach of the record’s user (Pagano and Ragan 1992) – so the assessment process of a medic will differ from that of a nurse, and both will differ from that of a therapist. It is essential that, whenever possible, consent is obtained from the cli­ ent before assessment is initiated. This consent must be informed and the clinician has the responsibility to make sure that the client understands the nature of any assessment procedures, their purpose and any risks. Consent, whether it is given verbally, in writing or by implication, must be recorded in the notes. See the section in this chapter on ‘Writing a Careplan’ for a fuller discussion on recording consent and communicating risk. In general, the type of client data that is collected in assessment will in­ clude information about: ° physical signs, symptoms and behaviours that indicate the client’s current health status ° current health care (for example information on medication, other illnesses) 48 WRITING SKILLS IN PRACTICE ° psychological factors (for example mood and client’s response to the problem) ° psychosocial factors (for example culture, religion) ° predisposing factors to the problem ° cognitive skills (for example memory, language skills) ° environment (for example type of housing or support from family) ° lifestyle (for example habits, diet and exercise) ° daily living pattern (for example working, retired or looking after young children) ° self-care abilities ° risk factors (for example is the client prone to falls? In children you will also want to include information about developmental and behavioural patterns (Cohen 1983). Client data is used by the clinician: ° to identify the health problem, formulate a diagnosis and determine the likely prognosis ° to determine the need for further in-depth assessment or referral to other professionals ° to provide a baseline measure for evaluating progress ° to establish the need for intervention and prioritise individual clients within the general caseload ° to help plan intervention and set realistic outcomes ° to help plan for discharge. Taking a case history is an essential first step in collecting relevant client data.

These methods and procedures are described in the statistics books listed at the end of this chapter erectile dysfunction treatment devices . If your research requires the use of purposive sampling techniques psychological erectile dysfunction young , it may be difficult to specify at the beginning of your research how many people you intend to contact free sample erectile dysfunction pills . Instead you continue using your chosen procedure such as snowballing or theoretical sampling until a ‘saturation point’ is reached. This was a term used by Glaser and Strauss (1967) to describe that time of your research when you really do think that everything is complete and that you’re not obtaining any new information by continuing. In your written report you can then describe your sam- pling procedure, including a description of how many people were contacted. SUMMARY X If it is not possible to contact everyone in the research population, researchers select a number of people to contact. X There are two main types of sampling category – prob- ability samples and purposive samples. X In probability samples, all people within the research population have a specifiable chance of being selected. Only within random samples do participants have an equal chance of being selected. X The size of sample will depend upon the type and pur- pose of the research. X Remember that with postal surveys it might be difficult to control and know who has filled in a questionnaire. X In some purposive samples it is difficult to specify at the beginning of the research how many people will be contacted. X It is possible to use a mixture of sampling techniques within one project which may help to overcome some of the disadvantages found within different procedures. This is a document which sets out your ideas in an easily accessible way. Even if you have not been asked specifically to produce a research proposal by your boss or tutor, it is a good idea to do so, as it helps you to focus your ideas and provides a useful document for you to reference, should your research wander off track a little. Before you start work on your research proposal, find out whether you’re required to produce the document in a specific format. For college and university students, you might be given a general outline and a guide as to how many pages to produce. For those of you who are produ- cingaproposaltosendtoafundingorganisationyou might have to produce something much more specific. Some provide advice and guidance about what they would like to see in your proposal. The larger funding bodies produce their proposal forms on-line so that they can be filled in and sent electronically, which makes the process a lot quicker and easier. This rationale should be placed within the con- text of existing research or within your own experience and/or observation. You need to demonstrate that you know what you’re talking about and that you have knowl- edge of the literature surrounding this topic. If you’re un- able to find any other research which deals specifically with your proposed project, you need to say so, illustrat- ing how your proposed research will fill this gap. If there is other work which has covered this area, you need to show how your work will build on and add to the existing knowledge. Basically, you have to convince people that you know what you’re talking about and that the research is important. Aims and objectives Many research proposal formats will ask for only one or two aims and may not require objectives. However, for some research these will need to be broken down in more depth to also include the objectives (see Example 6). The aim is the overall driving force of the research and the ob- jectives are the means by which you intend to achieve the aims. HOW TO PREPARE A RESEARCH PROPOSAL / 57 EXAMPLE 6: AIMS AND OBJECTIVES Aim To identify, describe and produce an analysis of the interact- ing factors which influence the learning choices of adult re- turners, and to develop associated theory.

At 5 years after osteotomy erectile dysfunction zurich , all cases had improvements erectile dysfunction medication for high blood pressure , with “good” or “fair impotence klonopin ,” but after 10 years, we started to see “poor” cases again. JOA Score 90 80 70 60 Total Score 50 Pain Gait 40 ROM ADL 30 20 10 0 Fig. At 18 years after VFO, a very good remodeling had been achieved with widening of the joint space and near nor- malization of the trabecular structure. After VFO, gradual resorption of the anterolateral part of the head that is not functioning had occurred. With VFO, the old femoral head is further pushed out anterolaterally and loses its function. The inclined weight- bearing surface showed significant osteosclerosis and cyst formation on the preopera- tive radiogram (Fig. At 19 years later, the roof osteophyte gradually grew and matured to a horizontal direction, widening the weight-bearing surface (Fig. I present the characteristic radiographic change during the initial stage after VFO. The X-ray finding taken at 3 months after VFO showed hinge adduction between capital drop and double floor and remarkable bone atrophy in the previous weight-bearing area (Fig. In general, marked bone atrophy occurs within 3 to 6 months postoperatively, which disappears almost completely within 1 year. In addi- tion, the weight-bearing area has widened by a horizontally grown roof osteophyte, making a stable joint a b c Fig. Appearance of marked bone atrophy of the previous weight-bearing area during 3–6 months after surgery is a characteristic finding in patients who have a favorable postopera- tive course. If a roof osteophyte is initially present, it further grows and eventually reaches maturation. Survivorship analysis was conducted taking either the time of conversion to THR or the time when the JOA hip score was less than 50 as the endpoint. It is clear that at 15 years, 59% for VFO alone, and 58% for VO plus Chiari’s pelvic osteotomy, are seen, the latter group being somewhat inferior (Fig. VO, valgus osteotomy Complications of VFO The complications of the operation included 4 cases of intraoperative fracture; 2 were a highly comminuted head fracture and they were excluded from the analysis. There were 3 cases of transient sciatic nerve paresis in Chiari combination. Seven cases had superficial infection and 3 cases delayed healing and non-union. The latter cases were successfully treated by addi- tional procedures such as implant exchange with bone graft. Contributing Factors on Clinical and Radiologic Results As for the factors contributing to clinical results, Maistrelli et al. Our series showed that the results are very poor when the range of motion of the joint was less than 40°. Cysts disappeared in about 3 months to 1 year; osteosclerosis began to disappear somewhat later than the disappearance of cysts; for the growth of roof osteophyte, only 1 of 6 cases without an initial presence of roof osteophytes showed new growth. If roof osteophytes were present at the beginning, and if the initial size was about 6–10mm, good growth and maturation were observed in more than half the cases. In cases where roof osteo- phytes are absent, we cannot expect new growth. He said that preoperative AHI must be 60% for OA Joint Reconstruction Without Replacement Surgery 173 Table 1.

However, successful cases had preoperative AHI of 70%–73%; AHI immediately postoperative was 73%, the length of the roof osteophyte was 8. Other factors, such as age, body mass index (BMI), Sharp’s angle, or the size of the capital drop, were not directly associated with the results (Table 1). Discussion of the Biological and Biomechanical Mechanism of VFO Now I turn to a discussion of the biological and biomechanical mechanism of VFO. The basic idea is that biological effects can be introduced with the improvement of the biomechanical environment in the diseased hip joints. To ascertain the biological effect, we performed histological evaluation of 15 joints with good postoperative remodeling of the articular surface.

Recent data have shown marked reduction in bioavailability of chemotherapy metabolized by the cytochrome P450 mono-oxygenase system impotence definition , when patients concurrently receive the enzyme- inducing anticonvulsants phenytoin erectile dysfunction university of maryland , phenobarbital varicocele causes erectile dysfunction , or carbamazepine. For these children, if chronic anticonvulsant therapy is warranted, selection of a non-enzyme-inducing agent, such as gabapentin, levetiracetam, lamotrigine, or topiramate, is preferable to avoid this complication. Furthermore, carbamazepine and valproic acid are avoided owing to their potential bone marrow myelosuppression. MYELOPATHY The neurologist should always think beyond cerebral processes and consider myelo- pathy to explain motor loss, sensory deficit with a dermatomal level, or autonomic (i. Spinal irradiation, months to years after its administration, can lead to myelopathy, often symmetric. Intrathecal agents, 258 Fisher Neurologic Effects of Cancer 259 260 Fisher Table 3 Differential Diagnosis for Stroke in the Child with Cancer Acute promyelocytic leukemia Chemotherapeutics BCNU (carmustine) intra-arterial Cisplatin intra-arterial l-Asparaginase Hyperleukocytosis, in leukemia Intratumoral hemorrhage—high-grade astrocytoma, medulloblastoma Methotrexate-associated stroke-like events days to a week plus after intravenous high dose Neuroblastoma metastatic to the dura or torcula Platelet-resistant thrombocytopenia such as cytarabine, methotrexate, and thiotepa, can cause acute to subacute spine necrosis, specifically when these drugs distribute unevenly in the subarachnoid space because of blockage from tumor. Nuclear medicine studies with technetium or indium can often demonstrate blockage in the presence of leptomengineal disease, even when spine MRI appears to show patent spaces. SPINAL CORD COMPRESSION The most alarming cause of myelopathy in the oncology patient is compression of the spinal cord by tumor. Tumor most often infiltrates through intervertebral foramina, unlike in adults where vertebral body involvement is more often found. Epidural tumor spread through the foramina is seen most frequently with Ewing sarcoma, neuroblastoma, osteosar- coma, rhabdomyosarcoma, Hodgkin disease, and non-Hodgkin lymphoma. Spinal subarach- noid tumor can develop with leukemia and ‘‘drop metastases’’ from the primary brain tumors medulloblastoma, embryonal tumors, ependymoma, and astrocytoma. In addition to the signs of myelopathy already described, these patients com- monly have exquisite back pain and localized tenderness to percussion over the spine. For children suspected to harbor pathology of the inferior cord, spending con- siderable time distinguishing between localization to the conus medullaris (i. Instead, to expedite diagnosis for any child suspected to have spinal cord compression, spine MRI is always the study of choice. Emergent treatment of spinal cord compression should commence with dexa- methasone 1 mg=kg intravenously. In suspected cases of lymphoma, the oncolytic effect of steroids can be so profound that biopsy should be performed immediately to confirm diagnosis. For some tumors, laminectomy and posterior decompression may suffice as initial therapy, along with steroids. Surgery is particularly recom- mended as initial therapy when the primary tumor is unknown and another easily accessible disease site cannot provide the diagnosis, all or most of the neoplasm can be removed, or relapse occurs during or after maximal radiotherapy. Thrombo- cytopenia and coagulopathy should be corrected before surgery (or before lumbar puncture, as described above) is attempted. If the diagnosis is known and the tumor radioresponsive, then radiotherapy is the therapy of choice. A few reports of initial chemotherapy for young children with spinal cord compression and newly diagnosed neuroblastoma, Ewing sarcoma, germ cell tumors, and osteo- sarcoma have shown efficacy, but the symptomatology of these patients is often minimal and the choice of therapy nonrandomized. ATAXIA As ataxia connotes simply incoordination, the clinician should exclude cerebral or spinal processes already described before localizing the process to the cerebellum. Nevertheless, a number of agents are known to produce cerebellar ataxia, particu- larly cyclosporine, cytarabine, 5-fluorouracil, ifosfamide, intrathecal methotrexate, and procarbazine. The ataxia with cytarabine is most often seen when the drug is 2 administered in high dosage, e. Cytarabine injures Purkinje cells and the ataxia typically but not always resolves spontaneously. Although this chemother- apeutic is key in the treatment of AML, whether a child whose ataxia resolves should be re-challenged with this drug is unclear. While paraneoplastic syndromes are rare in children, opsoclonus-myoclonus associated with ataxia in a toddler can be the harbinger of thoracic or abdominal neuroblastoma. As opsoclonus-myoclonus is an autoimmune reaction associated with humoral response to neuroblastoma, the syndrome often resolves with just therapy of the tumor. In some instances, the autoimmune response can cause 262 Fisher more extensive or persistent neurologic damage. Isolated reports have described improvements to persistent neuroblastoma-associated opsoclonus-myoclonus with use of prednisone, ACTH, or intravenous immunoglobulin. NEUROPATHY Neuropathy, in general, is rare in children but in the oncology setting seen most often with vincristine or cisplatin.

Baker believes that assessing mobility is central to his medical mission: If we don’t pay attention to people’s function in the face of their ill- nesses, then we have really cut ourselves off from the biggest oppor- tunity we have to help as doctors. We have violated the social con- tract of why society gives us so much, puts so much faith in us, allows us to set our own agenda, and pays us better than most peo- ple.... Weall went into medicine, despite fantasies of cure, wanting to be helpful. Major primary care textbooks say little about evaluating gait (Goroll, May, and Mulley 1995; Barker, Burton, and Zieve 1999; Noble 2001; Up- to-Date 2001). Baker suggests, the value of performing functional evaluations seems self-evident. At a minimum, assessments show how people func- tion now, the baseline for tracking progressive impairments and pre- dicting prognoses (American Medical Association 1996; Pearson 2000). Mobility evaluations are essential for planning interventions, like reha- bilitation or physical or occupational therapy, and considering mobility aids. Evaluations also serve administrative purposes, supporting docu- mentation required to ensure payment for professional services or assistive devices (chapters 13 and 14). Tools exist to evaluate walking, re- quiring nothing more sophisticated than just a hallway, chair, and stop- watch (Tinetti 1986; Tinetti and Ginter 1988; Mathias, Nayak, and Isaacs 1986). Yet little “hard evidence” supports the value of functional evalua- tions. Few randomized, controlled trials have examined the benefits (or risks) of assessing function. Janet Posner, a general internist, “and those holes make it hard to convince other people.... Ithink it would be easier to sell func- tional evaluations if we really had hard outcomes data. Physicians Talking to Their Patients / 153 No large studies have examined whether and how physicians assess mo- bility or other functional abilities. The 1994 NHIS did ask whether health- care providers inquire about problems with daily activities. People with mobility difficulties are much more likely than others to have been asked: just over 25 percent of persons with major mobility problems. Unlike medication errors that can be dramatic and life-threatening, lapses in evaluating patients’ functional abilities are unlikely to attract pub- lic attention. Magaziner ob- served, “they’re not going to care if you asked about someone’s gait. Joel Miller, being good at evaluating walking is “not something that is solidly, unquestionably, part of a doctor’s competence re- sponsibility in the same way as skill in breast exams. On the other hand, if I relate to my patients in a relatively mechanical, biomedical, purely medical kind of way and don’t ask about functioning, then that’s style. Only a few ask their patients to walk down the corridor and formally evaluate their gait. Most rely instead on the “history,” the accounts people give of their recent symptoms and physical difficulties, to identify mobility problems. Such assessments differ from other aspects of medical evaluations where histories are only the starting point: physicians then insist on observing or exploring potential problems themselves. People with major medical illnesses compromising endurance, like heart or lung disease, are a special case. Physicians have long used patients’ abilities to walk or perform other physical activities as explicit clinical in- dicators of the severity of these illnesses. The physician interviewees re- port carefully questioning patients with congestive heart failure or chronic obstructive pulmonary disease about how far they can walk before becom- ing short of breath or unable to go on. One physician reported that patients hate to admit having fallen, so he asks, “Have you found yourself on the floor unexpectedly?

Minimally invasive surgery erectile dysfunction treatment vacuum constriction devices , Total hip arthroplasty Introduction Less-invasive surgery has become a trend in every surgical discipline erectile dysfunction treatment photos . Examples are laparoscopic cholecystectomy which has largely replaced open cholecystectomy in general surgery erectile dysfunction shots , minimally invasive robotic heart surgery where stenotomy is not necessary, and in orthopaedics where arthroscopic meniscal surgery has made open menisectomy obsolete. Not surprisingly, interest in less-invasive total hip replace- ment has emerged. What are the driving forces to lead surgeons to try less-invasive hip arthroplasty surgery? First, patients come to surgeons requesting it, often having researched the technique with the aid of the Internet or learned of the procedure through the popular Department of Orthopaedics, London Health Sciences Centre–University Campus, 339 Windermere Road, London, Ontario, N6A 5A5, Canada 183 184 C. Advantages and disadvantages for various different min- imally invasive surgery (MIS) total hip arthroplasty techniques Advantages Disadvantages Two incision Intranervous Fluoroscopy required Anterior Intranervous Femur difficult Direct lateral Small incision? These patients believe that there will be less pain and quicker recovery. Propo- nents of the procedure allege that patients who undergo total hip arthroplasty surgery via a minimally (less) invasive technique have significantly earlier ambulation, less need of walking aids, a more favourable and earlier discharge from hospital, decreased transfusion requirements, and better functional recovery. Less-invasive total hip arthroplasty surgery originated with the work of Heuter, Judet, and Keggi. In recent years it has been rediscovered and popularized by Sculco, Berger, and Dorr [3–5]. Minimally invasive total hip arthroplasty involves a smaller skin incision, usually between half to one quarter the length of a conventional skin incision for this surgery, and attempts to minimize the extent of associated soft tissue trauma. Berger defines MIS as surgery where “muscles and tendons are not cut”. Recent developments to aid successful MIS surgery have been the introduction of specialized instrumenta- tion, computer-assisted surgery, the utilisation of fluoroscopic guidance, and specific MIS implants. The success of conventional total hip arthroplasty surgery has relied on adequate exposure to allow visualization of both the acetabulum and proximal femur. This exposure enabled correct orientation of the implanted prostheses based on visualized anatomical landmarks. One of the concerns with minimally invasive techniques are that with a small incision the surgeon would have poor visualization and this could lead to malposition of the prostheses, neurovascular injury, and poor implant fixa- tion, therefore compromising the short- and long-term results of a procedure which has become one of the most successful advances in surgical technology of the twen- tieth century. Minimally invasive total hip arthroplasty has generated a lot of controversy within the orthopaedic community and a great deal of publicity in the popular press. Randomization was to either undergo total hip arthroplasty through a standard 16-cm incision or a short incision of less than 10cm. The authors concluded that minimally invasive total hip arthro- plasty performed through a single-incision posterior approach by a high-volume surgeon, with extensive experience in less-invasive approaches, was safe and repro- ducible. The study however showed no significant benefit between the groups in terms of the severity of post-operative pain, the use of post-operative analgesic medications, the need for blood transfusion, length of hospital stay, or early functional recovery. Minimally/less-invasive total hip replacement is an umbrella term used to en compass what is actually a “family” of operations. Each of which have advantages and disad- Minimally Invasive Hip Replacement Surgery 185 Fig. Intraoperative photograph shows position of specialized retractors during minimally invasive surgery (MIS) anterior approach vantage (Table 1). This family of less-invasive hip approaches includes anterior, anterolateral, direct lateral, posterior, and two-incision surgical approaches. Anterior Approach Technique A modified Smith–Peterson approach is used for a MIS anterior technique. It gives excellent visualization of the acetabulum, allowing acetabular preparation and implant inser- tion with relative ease. First, there is a very steep learning curve as it utilizes a less-common approach for arthoplasty surgery. Second, in this approach access to the femoral canal for implantation of the femoral stem is difficult, prompting many surgeons to use a radiolucent fracture table, fluoroscopy, and specialized implants (Fig. No level-one data have been published on the anterior MIS approach to total hip replacement. Two-Incision Approach Technique The two-incision technique was developed by Mears and popularized by Berger [1,4]. This approach utilizes a modified anterior Smith–Peterson incision, which is approxi- mately 4–6cm, directly over the femoral neck for preparation and implantation of the acetabular component.
