Extensor tendon repair in the emergency department.

Extensor tendon lacerations of the hand are commonly seen in the emergency department. These injuries can often be definitively managed by the emergency physician who has a working knowledge of the complex extensor mechanism anatomy plus basic surgical skills. A thorough initial assessment including a tourniquet examination for adequate exposure is the key to making the complete diagnosis. Surgical indications, materials, techniques, complications, and postoperative management involved in extensor tendon repair are reviewed. The emergency physician's decision to treat or refer these injuries will depend greatly on the clinical setting, familiarity with the procedure, and the availability of and relationship with appropriate consultants.
