Colles' wrist fracture   

Overview | Symptoms | Treatment | Prevention

Alternative names:

Buckle fracture; Transverse wrist fracture

Definition:

A break across the end of the main bone of the forearm (the radius), or both of the lower arm bones (the radius and ulna). A Colles' fracture results in a backward and outward position of the hand in relation to the forearm.

Considerations

The Colles' fracture is a common fracture in children and the elderly. It occurs when a person falls forward and then attempts to break the fall by throwing the hands forward. The impact of the hand on the ground and the sudden uptake of body weight by the wrist cause the ends of the radius and/or the ulna (the two bones in the forearm) to buckle just above the wrist.

The fracture may appear on an X-ray as a mild increase in density on the top side of the bone with a slight irregularity in the surface rather than a nice smooth line. Severe injuries will show evidence of a fracture through the entire bone.

Treatment may range from simple immobilization with a splint and sling to a lightweight fiberglass cast. If cast immobilization is insufficient to repair the fracture, surgical intervention with internal fixation with pins, or a plate and screws may be necessary.

Older people with Colles' fractures often fail to regain full mobility of the wrist joint. Carpal tunnel syndrome may occur as a late complication of the injury. Chronic pain may result from injury to the ligaments or the joint surface of the wrist. In addition, in older patients, the fracture is usually related to osteoporosis, so treatment for osteoporosis is advised.

Causes

This injury is usually the result of trauma from a fall in which the person attempts to break the fall using the hands and arms. It is frequently associated with such sports as rollerblading, skateboarding, running, or any other activity in which the hands may be called upon to prevent a foreword fall occurring at relatively high speed.
