Treatment is a short arm cast for 3 weeks. In adults, the most common radial fracture is the Colles' fracture, which is extra-articular and occurs 2.5 to 3 cm proximal to the articular surface of the distal radius. Reduction by traction and manipulation can be performed. After reducing the fracture, a plaster short-arm cast is applied for 5 to 8 weeks. If nondisplaced, casting for 6 weeks without reduction is indicated.
Tenderness is localized to the injured metacarpal bone.
Radiographs reveal a fracture of the involved metacarpal or subluxation at the carpometacarpal joint. Nondisplaced fractures of the base of the metacarpals are treated with immobilization in a short arm cast. Displaced fractures are reduced by traction with local pressure over the prominent proximal end of the distal metacarpal fracture. A follow-up radiograph is necessary within 7 days. If any instability is noted after reduction or the fracture is comminuted, the patient should be referred to an orthopedist for open reduction and internal fixation.
