Primary care physicians must be able to recognize wrist and hand injuries that require immediate attention. A complete history and physical examination, including assessment of distal limb function, are essential. Hemorrhage control is necessary in patients with vessel lacerations and amputations. Amputations require an understanding of the indications and contraindications in the management of the amputated limb. High-pressure injection injuries and compartment syndromes require a high index of suspicion for early recognition. Infectious entities include 'fight bite,' open fractures, purulent tenosynovitis, animal bites, and retained foreign bodies. Tendon disruptions should be recognized early to optimize management.

Diagnosis of upper extremity injuries depends on knowledge of basic anatomy and biomechanics of the hand and wrist. The wrist is composed of two rows of carpal bones. Flexor and extensor tendons cross the wrist to allow function of the hand and digits. The ulnar, median, and radial nerves provide innervation of the hand and wrist. A systematic primary and secondary examination of the hand and wrist includes assessment of active and passive range of motion of the wrist and digits, and dynamic stability testing. The most commonly fractured bone of the wrist is the scaphoid, and the most common ligamentous instability involves the scaphoid and lunate. [ABSTRACT FROM AUTHOR]

Lumbosacral back pain is one of the most common reasons for patients with a work-related injury to present to a primary care physician. In most cases, low back pain has a good prognosis, but the condition is often the source of much frustration for clinicians, patients and employers. The family physician should be able to treat the patient's symptoms and address the psychosocial issues that frequently complicate recovery. Three decision points, based on the history and physical examination, allow the physician to determine the severity of illness and implement an appropriate treatment plan. These three points are as follows: Is it likely that systemic disease or bone pathology is the cause of pain? Has neurologic compromise occurred? Are social or psychologic stressors present that may prolong the clinical course? [ABSTRACT FROM AUTHOR]
