Regional Examination of the Musculoskeletal System (REMS): a core set of clinical skills for medical students.

OBJECTIVES: The aim of this study was to determine an agreed set of core regional musculoskeletal examination skills for medical students to learn. METHODS: Initially focus groups were undertaken amongst Rheumatologists, Orthopaedic Surgeons, Geriatricians and General Practitioners. These findings were used to inform the production of a questionnaire survey. The findings from both the questionnaire survey and focus groups were assessed using a group nominative technique with national representation from each of the four specialties involved. RESULTS: This process has led to the identification of 50 items, considered to be core regional musculoskeletal examination skills for medical students. CONCLUSIONS: This core set of musculoskeletal clinical skills may now be used to inform the production of teaching materials aimed at medical students.

Revised medical criteria for determination of disability, musculoskeletal system and related criteria. Final rules with request for comments.

We are revising the criteria in the Listing of Impairments (the listings) that we use to evaluate musculoskeletal impairments in adults and children who claim Social Security or Supplemental Security Income (SSI) benefits based on disability under titles II and XVI of the Social Security Act (the Act). There visions reflect advances in medical knowledge, treatment, and methods of evaluating musculoskeletal impairments. When the final rules become effective, we will apply them to new applications filed on or after the effective date of the rules and to other claims described in the preamble. Individuals who currently receive benefits will not lose eligibility as a result of these final rules. Also, although some individuals with musculoskeletal impairments will not meet the requirements of these final listings, they may still be found disabled at a later step in the sequential evaluation process based on their functional limitations.

Effect of electrical stimulation on musculoskeletal systems; a meta-analysis of controlled clinical trials.

This study was a meta-analysis to examine whether electrical stimulation has specific effects in the healing of musculoskeletal repair process and in the diminution of symptoms with bone and joint disorders. Using MEDLINE (1966-1999) and EMBASE (1985-1999) a search for articles was carried out with four medical subject headings. Data were extracted from all the accessed articles and additionally collected from appropriate journal lists. A total of 20 randomized controlled trials on bones was identified which assessed healing of fractures, bone graft, and other conditions; and 29 randomized controlled trials on soft tissues and joints were also found, dealing with healing of skin wounds or dermal ulcers, soft tissue injury, and other conditions. Using criteria through which the quality of studies was assessed, the content of the articles was reorganized into a tabular form. The majority of the identified articles reported positive findings, but all the trials showed methodological flaws to some extent. Because of heterogeneity of the studies and the various outcome measurements, pooling of only part of the data was performed. The combined results of 12 trials on bones and 16 trials on soft tissues, the cases in which major endpoints were mainly union or healing rate, revealed statistically significant effects. The studies in this review had some methodological limitations, and the selected pooled trials do not constitute acceptable proof that electrical stimulation has specific effects on health. However, one cannot ignore the statistically significant positive findings reported in the trials, from which extracted data were able to be combined.

Primary tumors of the musculoskeletal system.

The excellent soft-tissue contrast and multiplanar imaging capabilities of MR imaging have led to its emergence as the most significant advance in the imaging of musculoskeletal tumors. MR imaging is the modality of choice for local staging, evaluating response to preoperative chemotherapy, and long-term follow-up in bone tumors. MR imaging is the most effective modality for both primary staging of soft-tissue malignancy and detecting recurrences. This article reviews the role of conventional spin echo techniques versus newer techniques, and then discusses the indications in the diagnosis, staging, evaluation of preoperative chemotherapy, and detection of recurrences in bone and soft-tissue tumors.

Expression of epithelial markers in malignant fibrous histiocytoma of the musculoskeletal system: an immunohistochemical and electron microscopic study.

We performed an immunohistochemical and ultrastructural study on 67 specimens of malignant fibrous histiocytoma (MFH) from 65 patients. Most of the tumors were musculoskeletal in origin and all presented clinically as a primary malignancy. The tumors were high grade and 57 of 67 were the storiform-pleomorphic subtype. Immunohistochemical studies were performed in 34 cases with both fresh-frozen and formalin-fixed tissue; in 33 cases only formalin-fixed tissue was available. The immunohistochemical panel included vimentin, various molecular weight keratins, epithelial membrane antigen (EMA), desmin, alpha-1-antitrypsin, and alpha-1-antichymotrypsin. Seventeen of 67 (25.4%) cases stained with one or more keratin antibodies. The low molecular weight cytokeratins demonstrated the most widespread and intense staining and, using fresh-frozen tissue, increased sensitivity. Epithelial membrane antigen was detected in 20.6% of cases and six of these cases also stained with keratin. The EMA staining was more focal and less intense than the keratin reactivity. The keratin- or EMA-positive cases were not distinguished by their light microscopic or ultrastructural features. Desmin staining was focally present in 16.9% of cases. The vast majority of tumors stained with vimentin and alpha-1-antitrypsin or alpha-1-antichymotrypsin. There was no staining of tumor cells for S-100. Appropriately fixed tissue was available for electron microscopic evaluation in 15 of 23 MFHs that stained with keratin or EMA. Ultrastructurally, all tumors were composed of an admixture of cells that had the features of fibroblasts, myofibroblasts, and histiocytes; no epithelial structures were identified. This study confirms that MFH may express epithelial markers. It emphasizes the importance of using electron microscopy and clinical findings to distinguish keratin or EMA-positive MFH from carcinoma. This distinction is important because of the significant differences in therapy and prognosis.

Symptoms of the musculoskeletal system and exposure to magnetic fields in an aluminium plant.

OBJECTIVE: The study was performed to examine the influence of the exposure to magnetic fields in the potrooms of an electrolysis plant on the occurrence of musculoskeletal symptoms among the employees. The study was performed after much discussion and worry in the aluminium industry about this issue. METHODS: A retrospective cohort study was performed at an aluminium plant. The occurrence of musculoskeletal symptoms registered at health controls performed by the occupational health care unit in 1986 and 1991 was assessed from employees exposed to magnetic fields in the potrooms (n = 342) and from a control group (n = 277). The data were collected before the discussion about the effects of magnetic fields started. The exposure to static magnetic fields was found to be 3-20 mT inside the potrooms. Ripple components (alternating currents (AC fields)) were registered as well. RESULTS: No difference between the exposed and unexposed groups was found for the reported musculoskeletal symptoms in 1986 or in 1991. CONCLUSIONS: There seems to be no relation between work in potrooms with exposure to static magnetic fields and the occurrence of musculoskeletal symptoms.

Magnetic resonance imaging of the musculoskeletal system. Part 6. The Shoulder.

The role of magnetic resonance imaging in the diagnosis and treatment of patients with shoulder pain has increased remarkably in recent years, largely because of improved resolution of images and increased experience of musculoskeletal radiologists. In rotator cuff disease/impingement and instability, magnetic resonance imaging adds a new dimension to the clinical findings through the noninvasive visualization of either the pathology itself or frequently associated abnormalities. It is the associated abnormalities that are depicted in instability: glenoid irregularities, labral tears, capsular laxity, and Hill-Sachs deformities. Glenoid, labral, and Hill-Sachs abnormalities can be assessed with either magnetic resonance imaging or computed tomography arthrography. Magnetic resonance imaging has the advantages of noninvasiveness, multiplanar imaging capability and exquisite soft tissue contrast. In rotator cuff disease, magnetic resonance imaging depicts the status of the rotator cuff itself, revealing partial and full thickness tears, allowing an estimation of size and quality of tendon edges. Possible impingement sites can be identified. Primary instability with secondary impingement may be first suspected on magnetic resonance imaging. Postoperative complications, including recurrent tendon detachment, deltoid dehiscence, and infection, are clarified. Unsuspected but clinically important lesions, such as neoplasm, osteonecrosis, and ganglion with entrapment of the suprascapular nerve, each have characteristic magnetic resonance imaging appearances.
