Comminuted Fracture Definition

A comminuted fracture is a break or splinter of the bone into more than two fragments. Since considerable force and energy is required to fragment bone, fractures of this degree occur after high-impact trauma such as in vehicular accidents.

External fixation devices such as splints and casts are usually inadequate in treating this type of fracture. Repairing a comminuted fracture often requires open surgery to restructure the bone to normal anatomy.
