Hand Injuries, Part 3: Fractures, Dislocations, Nail Bed Trauma, and Bites
March 1st 2005ABSTRACT: To determine the stability of the injury, examine phalangeal and metacarpal fractures for intra-articular involvement. Suspect carpal bone fracture in any patient with wrist pain and tenderness; proper splinting is essential to prevent avascular necrosis of the bone, arthritis, and chronic disability. After successful reduction of a distal or proximal interphalangeal joint dislocation, order follow-up x-ray films. Apply stress testing of the joint space to all injured joints to ensure ligamentous integrity. Carpal and carpometacarpal dislocations require immediate consultation with a hand specialist. Therapy for bite wounds includes copious irrigation, debridement (in the operating room if necessary), and antibiotic prophylaxis. A patient with an infected bite wound requires hospitalization and intravenous antibiotics.
