In the daily practice of family medicine, injuries to the upper extremity are frequently encountered. Most of these injuries can by easily treated by the primary care physician who has an understanding of the joint anatomy and treatment principles. Some injuries, however, may appear relatively minor, yet require prompt referral for surgical care. We reviewed the pathoanatomy, historical and physical examination findings, and treatment of the more common injuries to the hand, wrist, elbow, and shoulder.
Upper extremity (UE) dysfunction attributed to overuse is an increasingly prevalent problem managed with interdisciplinary rehabilitation. Outcome evaluation of these programs is limited by a number of factors. First, patients with UE dysfunction include a wide variety of pathophysiologic processes and diagnoses that are associated with multiple secondary impairments, disabilities, and handicaps that limit personal performance. Second, the particular experience of disablement and expectations each person brings to the rehabilitation process necessitates an individualized program with unique goals. Successful outcome measurement of the rehabilitation process must take into account the achievement of individual goals as well as objective scalar quantification of impairments, disabilities, and handicaps that are comparable between groups. Understanding of the relationships between UE impairments and given functional outcomes will come from controlled, dosed treatment studies in "pure" diagnostic patient groups. Outcomes research applied to UE rehabilitation as it is currently practiced should include individually devised patient assessments of accomplishment and satisfaction in addition to long-term quantitative reassessment of the person under all domains of disablement and work performance.
Upper extremity musculoskeletal disorders may occur as a result of work with keyboard-equipped video display terminals. Many studies of the associations between keyboard use and upper extremity disorders have appeared in both the human factors and occupational epidemiologic literature. Methodological limitations and inconsistent results have limited conclusions that can be made from these studies, however. Although exposure conditions can be carefully controlled, human factors studies are limited by relatively small sample sizes, short exposure durations, and reliance on outcome measures with unknown relevance to chronic adverse health effects. Epidemiologic studies have been limited by poor ascertainment of both exposure and health outcome. Many have failed to control for any potential confounding. An almost exclusive reliance on cross-sectional study designs has resulted in possible bias from selective survival, exposure-effect reversal, and poor estimates of exposures occurring prior to development of the disorder. Given the inconsistency in the literature and the growing controversy surrounding this issue, prospective study of this question using objective methods for assessment of exposure and health outcome is recommended. This design allows identification of incident cases and minimizes bias from selective survival. In addition, ergonomic and psychosocial variables prior to onset of symptoms can be ascertained periodically. Given estimates for up to 100 million video display terminals to be in use in the United States by the year 2000, clarification of the health effects of their use is critical.
