The benefits of total hip replacement in 49 people aged 55-84 with osteoarthrosis of the hip were evaluated. The main benefit was relief of symptoms, 40 patients being pain free after operation. Range of hip movement and mobility improved moderately in most patients. After operation most patients were better able to perform certain activities of daily life, though only six were completely independent, the rest requiring aids or help from others. Nevertheless, 18 of the patients'' main helpers estimated that they had more time free of tasks previously performed for the patient. There was a small reduction in the need for community medical resources such as home visits from general practitioners or district nurses. Thirteen patients were still taking antiarthritic drugs. Older patients needed to spend longer in hospital after operation because of complications. It was concluded that total hip replacement contributed to improving the quality of life of patients and their helpers, while also helping to reduce the demand for community health and welfare services. 相似文献

Hip loading affects bone remodeling and implant fixation. In this study, we have analyzed the effect of subject-specific modeling of hip geometry on muscle activation patterns and hip contact forces during gait, using musculoskeletal modeling, inverse dynamic analysis and static optimization. We first used sensitivity analysis to analyze the effect of isolated changes in femoral neck-length (NL) and neck-shaft angle (NSA) on calculated muscle activations and hip contact force during the stance phase of gait. A deformable generic musculoskeletal model was adjusted incrementally to adopt a physiological range of NL and NSA. In a second similar analysis, we adjusted hip geometry to the measurements from digitized radiographs of 20 subjects with primary hip osteoarthrosis. Finally, we studied the effect of hip abductor weakness on muscle activation patterns and hip contact force. This analysis showed that differences in NL (41-74 mm) and NSA (113-140 degrees ) affect the muscle activation of the hip abductors during stance phase and hence hip contact force by up to three times body weight. In conclusion, the results from both the sensitivity and subject-specific analysis showed that at the moment of peak contact force, altered NSA has only a minor effect on the loading configuration of the hip. Increased NL, however, results in an increase of the three hip contact-force components and a reduced vertical loading. The results of these analyses are essential to understand modified hip joint loading, and for planning hip surgery for patients with osteoarthrosis. 相似文献

Pain in patients with hip osteoarthritis appears long before surgery, and requires effective management as it affects patient comfort and daily activities. Therefore, the search for factors influencing response rate to analgesics is mandatory. In recent years, increasing attention has been paid to genetic factors underlying pain threshold and treatment efficacy. Polymorphic gene of catechol-oxide-methyltransferase (COMT) is a candidate gene associated with pain pathology and treatment response. The aim of the study was to evaluate association between the COMT rs4680:G>A polymorphism and demand for analgesics in patients subjected to elective hip replacement. The study included 196 patients after hip replacement surgery. Opioid demand was recorded and analgesic efficacy was scored using a four-level verbal pain intensity scale. COMT rs4680:G>A polymorphism was analysed by PCR-RFLP method. The studied COMT genotypes did not influence opioid administration in the studied patients from the day of surgery till day 6 afterwards. The distribution of the COMT rs4680:G>A in the studied subjects was as follows: GA—52.04%, AA—23.98% and GG—23.98%. It can be concluded that the COMT rs4680:G>A polymorphism is not associated with opioid demand in patients after elective hip replacement. 相似文献

Two studies on 41 patients with osteoarthrosis of the hip or knee have shown fenoprofen—a compound with analgesic and anti-inflammatory properties—to be an effective addition to the drug treatment of these conditions. It was found to be superior to paracetamol but no statistically significant difference was shown in a comparison with phenylbutazone. 相似文献

Evidence was previously presented to support the thesis that chronic pain is activated by neuronal elements that make up the multisynaptic short axon core of the reticular system (Andy and Peeler 1985). The present thesis, that chronic pain is a reticular formation syndrome, is based on a retrospective analysis of four patients with chronic pain who were successfully treated with a lesion in the anterior thalamus and stimulation electrode implants in the posterior thalamus and pontomesencephalic brain stem. The reticular formation was the common underlying anatomic substrate at those three sites. In addition to chronic pain, all the patients had other symptoms attributable to other body organs and systems. The number and type of symptoms that made up the syndrome differed between patients. Symptoms making up the core of the syndrome were pain, anxiety, nervousness, insomnia, and depression. Experimental and clinical findings are briefly presented to demonstrate the various reticular formation sites, pragmatically considered "reticular functional systems," from which symptoms may arise. It is hypothesized that the symptoms are recruited by a low threshold "pain oscillator" that is generated at one reticular site and subsequently permeates the rest of the reticular system. Therapeutic stimulation inactivates the low threshold system by "jamming" it. 相似文献

There is a growing amount of evidence that alteration in pain processing by the peripheral and central nervous system play a role in osteoarthritis pain, leading to neuropathic-like symptoms. It is essential to identify knee and hip osteoarthritis patients with a neuropathic pain profile in order to offer such patients education and additional treatment options besides conventional pain treatment. The painDETECT Questionnaire is a self-report questionnaire developed to discriminate between nociceptive and neuropathic pain. This questionnaire was modified to fit patients suffering from knee osteoarthritis. The aim of this study was to translate and cross-culturally adapt the modified painDETECT Questionnaire to the Dutch language and to provide a modified version to fit patients with hip osteoarthritis. Reliability for internal consistency, repeatability and floor and ceiling effects were subsequently assessed. A total of 278 patients were included in the reliability study and 123 patients in the repeatability analysis. The Dutch modified painDETECT Questionnaire shows good internal consistency and small relative measurement errors, represented by a good intraclass correlation coefficient. Absolute measurement error, represented by the Standard Error of Measurement, was acceptable. However, a measurement bias might be present when it comes to repeatability. To our knowledge, this study is the first to provide a Dutch modified painDETECT Questionnaire to fit hip and knee osteoarthritis patients and to assess internal consistency, reliability and agreement. International guidelines were followed in the translation process and this study has ample sample size with an adequate time interval for repeatability. Based on this study, the Dutch modified painDETECT Questionnaire seems to be fit as a discriminative tool to identify knee and hip osteoarthritis patients with a neuropathic pain profile. Whether it is also suitable as an evaluative tool to record changes over time or after an intervention remains open to further investigation. 相似文献

Chronic pain appears to be associated with brain gray matter reduction in areas ascribable to the transmission of pain. The morphological processes underlying these structural changes, probably following functional reorganisation and central plasticity in the brain, remain unclear. The pain in hip osteoarthritis is one of the few chronic pain syndromes which are principally curable. We investigated 20 patients with chronic pain due to unilateral coxarthrosis (mean age 63.25±9.46 (SD) years, 10 female) before hip joint endoprosthetic surgery (pain state) and monitored brain structural changes up to 1 year after surgery: 6–8 weeks, 12–18 weeks and 10–14 month when completely pain free. Patients with chronic pain due to unilateral coxarthrosis had significantly less gray matter compared to controls in the anterior cingulate cortex (ACC), insular cortex and operculum, dorsolateral prefrontal cortex (DLPFC) and orbitofrontal cortex. These regions function as multi-integrative structures during the experience and the anticipation of pain. When the patients were pain free after recovery from endoprosthetic surgery, a gray matter increase in nearly the same areas was found. We also found a progressive increase of brain gray matter in the premotor cortex and the supplementary motor area (SMA). We conclude that gray matter abnormalities in chronic pain are not the cause, but secondary to the disease and are at least in part due to changes in motor function and bodily integration. 相似文献

In double-blind cross-over studies in 46 patients with rheumatoid arthritis and in 42 patients with osteoarthrosis of the hip, Orudis—a new non-steroidal anti-inflammatory agent—has been shown to be well tolerated and to have comparable therapeutic efficacy with indomethacin when given in equal dosage. Side effects were less severe with Orudis. The results suggest that Orudis will prove valuable in the clinical management of rheumatic diseases. 相似文献

The incidence of different types of shoulder pain after open heart surgery was studied prospectively. Of 101 patients studied, 45 developed rheumatic symptoms during the first six weeks after the operation. Thirty eight patients reported pain in the region of the shoulder girdle with no loss of shoulder function (postpericardiotomy rheumatism). Three of these patients also had features compatible with the postpericardiotomy syndrome (fever, malaise, or pleuritic chest pain), and seven developed the syndrome without pain in the shoulder girdle. Of these 10 patients, one had generalised myalgia. Postpericardiotomy rheumatism alone was not associated with increased inflammation (measured by the erythrocyte sedimentation rate and concentration of C reactive protein); immunological tests including measurement of antibodies to cardiac muscle yielded inconclusive results. Replies to a postal questionnaire showed that symptoms of postpericardiotomy rheumatism were present for over three months in 18 patients and for six months or longer in 14. In view of the large number of patients now having open heart surgery postpericardiotomy rheumatism should be considered when patients report pain around the shoulders so that it is not misdiagnosed as angina. 相似文献

A questionnaire to establish the presence of 15 symptoms thought to be typical of the irritable bowel syndrome (IBS) was given to 109 unselected patients referred to gastroenterology or surgery clinics with abdominal pain or a change in bowel habit or both. Review of case records 17--26 months later established a definite diagnosis of IBS in 32 patients and of organic disease in 33. Four symptoms were significantly more common among patients with IBS--namely, distension, relief of pain with bowel movement, and looser and more frequent bowel movements with the onset of pain. Mucus and a sensation of incomplete evacuation were also common in these patients. The more of these symptoms that were present the more likely was it that the patient''s pain or altered bowel habit, or both, was due to IBS. We conclude that a careful history can increase diagnostic confidence and reduce the amount of investigation in many patients with chronic abdominal pain. 相似文献

The purpose of this case study is to demonstrate the treatment of patella-femoral knee pain in an adolescent female athlete with emphasis on neuromuscular training of the knee and hip in synergy movement strategies. A 1.67-m, 61.5-kg, 15-year-old woman athlete reported to rehabilitation with the complaint of a 1-year history of bilateral knee pain. The patient noted that the symptoms were exacerbated with any sports-specific training. The patient played softball as an infielder. The athlete was referred by her family practice physician. After the patient was assessed, a clinical hypothesis was generated. It was thought that neuromuscular dysfunction of the hips and knees was causing faulty knee mechanics. These abnormal mechanics were presenting as patella-femoral knee pain. Initially, the athlete was assigned a home exercise program of side-lying hip abduction and lateral step-downs. At her first follow-up appointment, she noted increased symptoms that were aggravated with her home program. Upon inspecting her exercise technique, faulty step-down mechanics were contributing to her symptoms. Step-downs were discontinued, and the patient was instructed in and performed a chair squatting exercise, which was added to her home program. At her next follow-up, the patient noted being asymptomatic for 2 days. Her exercises were increased in intensity to include a Stairmaster and hip abduction and adduction on a 4-way hip machine. Eventually, over her treatment course, perturbation and proprioceptive training were initiated. By the sixth visit, the patient reported no symptoms and felt comfortable with self-management. A phone interview 3 months later indicated that the patient had no recurrent symptoms and was participating in sports without difficulty. This case demonstrates effectiveness of using hip and knee joint synergy to treat patella-femoral pain (PFP). The use of this synergy promotes proper patella–femoral alignment and improved knee mechanics. This case also is unique in the lack of physical agents and taping used to improve the patient's condition. It reinforces how exercise technique can carry over to functional athletic activities. This study provides a case for the use of hip and knee mechanical retraining in the treatment of PFP in adolescent female athletes who do not exhibit abnormal foot mechanics in weight bearing. It is important that sports medicine professionals be aware of these treatment options and are able to use them to correct these deficits in order to facilitate return to training and competition as quickly and safely as possible. 相似文献

The aim of this study was to evaluate the impact of total hip or knee arthroplasty upon quality of life in elderly patients. The study was carried out at the Clinic for Orthopaedic Surgery Lovran on 74 total hip arthroplasty and 70 total knee arthroplasty patients. All patients had completed the Medical Outcomes Study 36-Item Short Form in the week having preceded their surgery and then again postoperatively, 2 years after. The data obtained were statistically processed at the level of physical function, role limitations due to physical problems, role limitations due to emotional problems, social function, mental health, energy or vitality, pain and general health perception, and change in health. The primary total hip arthroplasty patients showed significant improvement at all levels measured. Similarly, the primary total knee arthroplasty patients expressed significant improvement according to all the parameters but the mental health assessment. Comparison of outcomes between the two assessment groups of patients resulted in slightly superior quality of life outcomes in total hip arthroplasty patients. It can be concluded that total hip or knee arthroplasty significantly enhances the health related quality of life in elderly patients. 相似文献
