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.

Rupture of a flexor tendon in the nonrheumatoid population is rare. Localizing the level of the tendon rupture can be a difficult task. We describe an individual who presented with the sudden inability to flex the index finger of the hand, which had been subjected to a severe electrical injury. Physical exam demonstrated lack of index finger flexion at the distal joint. The patient denied any pain or history of recent trauma. Preoperative magnetic resonance imaging (MRI) successfully located the proximal and distal ends of the ruptured flexor digitorum profundus tendon in the forearm. MRI allows for accurate preoperative assessment of tendon position and degree of retraction, thereby facilitating surgical planning and approach. Accurate localization of tendon pathology preoperatively minimizes unnecessary dissection, shortens the operative procedure, and clarifies operative planning.
