Outpatient use of low molecular weight heparin (Dalteparin) for the treatment of deep vein thrombosis of the upper extremity.

Upper extremity deep vein thrombosis (DVT) is now recognized as a major cause of morbidity and mortality. There is little information regarding the most effective treatment of this condition. We report a prospective cohort study of the use of low molecular weight heparin (LMWH) in the outpatient management of upper extremity DVT. Forty-six patients were managed as outpatients for objectively documented upper extremity DVT with dalteparin (200 aXa u/kg), for a minimum of five days. Warfarin was usually initiated on the first day with a target INR of 2.0-3.0. Most patients had an underlying malignancy or a history of a central line. All patients were followed for 12 weeks from diagnosis. Only one patient had a major bleed. No patients developed pulmonary emboli. One patient had a recurrence of DVT during the treatment with LMWH with extension of the existing thrombus. Seven patients died, all due to their underlying disease. This study supports the safety and effectiveness of dalteparin in the treatment of upper extremity DVT. Given that these patients were treated as outpatients, there is a potential for huge cost savings.

Electrodiagnostic approach to the patient with suspected mononeuropathy of the upper extremity.

Upper extremity mononeuropathies are common. Most are due to compression, whereas others occur in the setting of systemic disorders (e.g., diabetes) or with coexistent polyneuropathies. Electrophysiologic studies are essential in most cases, and provide critical information regarding localization, severity, activity, chronicity, and underlying pathophysiological mechanisms. Insights gleaned from the electrodiagnostic report guide clinicians in the optimal management of mononeuropathies of the upper extremity.

Compartment syndromes of the upper extremity.

Upper extremity compartment syndromes are difficult conditions that are manifest in a myriad of ways. Careful attention to the details of the history and physical examination can assist in the development of a useful working diagnosis. Testing ITPs is the best method available to help confirm the diagnosis. Prompt fasciotomy is effective for diminishing compartment pressure and limiting additional tissue necrosis due to pressure elevation. Unfortunately, a number of characteristics specific to compartment syndrome affect ultimate outcome. Other variables, such as the amount of muscle damage from the initial injury, problems originating from any associated fracture, and soft tissue injury, also significantly affect overall patient outcome.

Volkmann's ischemic contracture of the upper extremity.

Upper extremity deformity of ischemic contracture usually includes elbow flexion, forearm pronation, wrist flexion, thumb flexion and adduction, digital metacarpophalangeal joint extension, and interphalangeal joint flexion. Treatment of mild contractures consists of either nonoperative management with a comprehensive rehabilitation program (to increase range of motion and strenght) or operative management consisting of infarct excision or tendon lengthening. Treatment of moderate-to-severe contractures consists of release of secondary nerve compression, treatment of contractures (with tendon lengthening or recession), tendon or free-tissue transfers to restore lost function, and/or salvage procedures for the severely contracted or neglected extremity.

The effect of upper extremity support on upper extremity posture and muscle activity during keyboard use.

Forearm support during keyboard use has been reported to reduce neck and shoulder muscle activity and discomfort. However, the effect of forearm support on wrist posture has not been examined. The aim of this study was to examine the effect of 3 different postures during keyboard use: forearm support, wrist support and "floating". The floating posture (no support) was used as the reference condition. A wrist rest was present in all test conditions. Thirteen participants completed 20 min wordprocessing tasks in each of the test conditions. Electromyography was used to monitor neck, shoulder and forearm muscle activity. Bilateral and overhead video cameras recorded left and right wrist extension, shoulder and elbow flexion and radial and ulnar deviation. The forearm support condition resulted in significantly less ulnar deviation (p < or = 0.007), less time spent in extreme ulnar deviation (p = 0.002) and less reports of discomfort than the "floating" condition (p = 0.002). The wrist support but not the forearm support condition resulted in less trapezius and anterior deltoid muscular activity (p < 0.007). These findings indicate that typing with upper extremity support in conjunction with a wrist rest may be preferable to the "floating" posture implicit in current guidelines.

Measuring functional outcomes in work-related upper extremity disorders. Development and validation of the Upper Extremity Function Scale.

Questionnaire-based measures of function have been validated extensively in studies of chronic illness and work-related low back pain. These measures have only recently been developed for upper extremity disorders (UEDs), and there is little information on their utility in evaluation of injured workers. We developed the Upper Extremity Function Scale (UEFS), an eight-item, self-administered questionnaire, to measure the impacts of UEDs on function. This instrument was tested in a cohort of 108 patients with work-related UEDs and 165 patients with the carpal tunnel syndrome (CTS); both groups were enrolled in prospective follow-up studies. The UEFS demonstrated excellent psychometric properties, including good internal consistency (Cronbach's alpha > 0.83), relative absence of floor effects, and excellent convergent and discriminant validity, compared with measures of symptom severity and clinical findings. In the CTS group, the UEFS was more responsive to significant improvements over time than clinical measures such as grip and pinch strength. These data support the use of a self-reported functional scale as a measure of outcome in studies of work-related UEDs. Further investigations in working populations are needed to substantiate its utility in workers with UEDs who have not yet sought medical care.

"Think nerve" in upper extremity reconstruction.

Upper extremity reconstruction may be greatly facilitated by "thinking nerve" in the initial evaluation. Frequently, the obvious soft tissue deformity or bone or joint pathology distracts the reconstructive surgeon from an underlying nerve problem. When pain is a portion of the presenting complaints, thinking nerve becomes more obvious. This article attempts to direct the reconstructive surgeon approaching the upper extremity to look for underlying nerve injury in the region of a damaged wrist capsule, neuromas of the cutaneous nerve, and sites of nerve entrapment.

Upper extremity bursitis.

Upper extremity bursae are injured through a number of processes, including overuse, hemorrhage, crystal deposition, autoimmune diseases and infection. These injuries may be disabling and can pose significant diagnostic and therapeutic challenges for the clinician. Treatment of the most common forms is directed at pain management and functional rehabilitation through a structured exercise program. Early recognition of infectious bursitis, followed by appropriate surgical and antibiotic treatment, is critical to prevent severe sequelae in these cases. This article reviews the pathophysiology, evaluation and treatment of the three most commonly involved upper extremity bursae: the subacromial, the olecranon and the subscapular bursae.

The Prosthetic Upper Extremity Functional Index: development and reliability testing of a new functional status questionnaire for children who use upper extremity prostheses.

The Prosthetic Upper Extremity Functional Index (PUFI) was developed by the authors' clinical research group to evaluate the extent to which a child actually uses a prosthetic limb for daily activities, the comparative ease of task performance with and without the prosthesis, and its perceived usefulness. The PUFI's test-retest and interrater reliability were evaluated with 24 children. Intraclass coefficients (ICCs) were calculated for each of four subscales of the PUFI--specifically, method of performance, ease of prosthetic use, usefulness of the prosthesis, and ease of performance without the prosthesis. The ICCs were greater than 0.65, indicating good test-retest reliability for the older-child respondents (n = 10) and fair to good reliability (ICCs, 0.40 to 0.84) for the parent respondents overall (n= 21). Interrater (child-parent) reliability was lower, with ICCs from 0.30 to 0.77. This finding was not unexpected, since a child and parent may rate in the context of different functional environments. The prosthesis was used 53% of the time by older children and more than 75% of the time by younger children. The results provide evidence that the PUFI has good test-retest reliability overall as a measure of a child's ability to perform upper extremity activities with a prosthesis.

A longitudinal study of industrial and clerical workers: predictors of upper extremity tendonitis.

Upper extremity tendonitis (UET) associated with work activity is common but the true incidence and risk factors can best be determined by a prospective cohort study. This study followed a cohort of 501 active workers for an average of 5.4 years. Incident cases were defined as workers who were asymptomatic at baseline testing and had no prior history of UET and went on to be diagnosed with an UET during the follow-up period or at the follow-up evaluation. The incident cases were compared to the subset of the cohort who also had no history of an UET and did not develop tendonitis during the study. The cumulative incidence in this cohort was 24.3% or 4.5% annually. The factors found to have the highest predictive value for identifying a person who is likely to develop an UET in the near future included age over 40, a BMI over 30, a complaint at baseline of a shoulder or neck discomfort, a history of CTS and a job with a higher shoulder posture rating. The risk profile identifies both ergonomic and personal health factors as risks and both categories of factors may be amenable to prevention strategies.

Development of an upper extremity outcome measure: the DASH (disabilities of the arm, shoulder and hand) [corrected]. The Upper Extremity Collaborative Group (UECG)

This paper describes the development of an evaluative outcome measure for patients with upper extremity musculoskeletal conditions. The goal is to produce a brief, self-administered measure of symptoms and functional status, with a focus on physical function, to be used by clinicians in daily practice and as a research tool. This is a joint initiative of the American Academy of Orthopedic Surgeons (AAOS), the Council of Musculoskeletal Specialty Societies (COMSS), and the Institute for Work and Health (Toronto, Ontario). Our approach is consistent with previously described strategies for scale development. In Stage 1, Item Generation, a group of methodologists and clinical experts reviewed 13 outcome measurement scales currently in use and generated a list of 821 items. In Stage 2a, Initial Item Reduction, these 821 items were reduced to 78 items using various strategies including removal of items which were generic, repetitive, not reflective of disability, or not relevant to the upper extremity or to one of the targeted concepts of symptoms and functional status. Items not highly endorsed in a survey of content experts were also eliminated. Stage 2b, Further Item Reduction, will be based on results of field testing in which patients complete the 78-item questionnaire. This field testing, which is currently underway in 20 centers in the United States, Canada, and Australia, will generate the final format and content of the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. Future work includes plans for validity and reliability testing.

Biobehavioral mechanisms of work-related upper extremity disorders: a new agenda for research and practice.

BACKGROUND: Epidemiological studies provide support for the role of organizational and individual psychosocial stressors in work-related upper extremity disorders (WRUEDs). Despite this evidence, the biological plausibility of a relationship between exposure to various psychosocial and work organizational stressors and WRUEDs remains unclear METHODS: The Georgetown Symposium on Biobehavioral Mechanisms of Work-Related Upper Extremity Disorders was held in Washington D.C. on November 6-7, 2000 to improve the understanding of potential biobehavioral mechanisms, identify future areas for research and discuss the implications of this body of knowledge for intervention. This meeting involved presentations and discussions by researchers and clinicians from a number of disciplines (epidemiology, occupational medicine, rheumatology, orthopedics, surgery, internal medicine, psychoneuroimmunology, occupational health psychology, behavioral medicine, psychophysiology and experimental and organizational psychology). RESULTS: The symposium generated several papers addressing the following topics: definitions and job stress models; epidemiological foundations; musculoskeletal and biomechanical models; central nervous system models of recurrent and persistent clinical pain; psychophysiology of work; and implications for intervention. These papers comprise this special issue. DISCUSSION: The present paper summarizes the various contributions to this special issue and provides direction for future research on potential biobehavioral pathways.

Composite in situ vein bypass for upper extremity revascularization.

Chronic upper extremity arterial insufficiency is rare. Consequently, major reports specifically limited to the topic are scarce, and the clinical experience is small. In addition, symptomatology, diagnostic criteria, and guidelines for surgical management remain ill-defined. In the lower extremities, however, in situ vein bypass has been attempted for nearly three decades. This technique offers many advantages over traditional revascularization methods. Although the procedure has become popular for the lower extremity, no report of its use in the upper extremity is found in the literature. We report what may be the first case in which in situ bypass was used in the upper extremity for a threatened limb secondary to diabetic occlusive vascular disease complicated by a previous shunt used for hemodialysis. Revascularization of the upper extremity using the in situ vein bypass technique may offer a new alternative to traditional methods of revascularization.

Imaging of upper extremity stress fractures in the athlete.

Although it is much less common than injuries in the lower extremities, an upper extremity stress injury can have a significant impact on an athlete. If an accurate and timely diagnosis is to be made, the clinician must have a high index of suspicion of a stress fracture in any athlete who is involved in a throwing, weightlifting, or upper extremity weight-bearing sport and presents with chronic pain in the upper extremity. Imaging should play an integral role in the work-up of these patients; if initial radiographs are unrevealing, further cross-sectional imaging should be strongly considered. Although a three-phase bone scan is highly sensitive in this regard, MRI has become the study of choice at most centers.

'Kissing lesions' of the thorax and upper extremity.

An upper extremity compressed beneath the body of a comatose individual can contribute to the development of a compartmental syndrome. Crushing injuries such as these can result in skin necrosis at the sites of contact between the chest wall and the compressed limb. These "kissing lesions" must be recognized as indicators of a severe crush injury and impending compartmental syndrome, as fasciotomy is urgently required.
