It is important to classify the type of fracture, because some fractures are more difficult to treat than others. Intra-articular fractures, open fractures, comminuted fractures, and displaced fractures (when the broken pieces of bone do not line up straight).are more difficult to treat, for example. Sometimes, the other bone of the forearm (the ulna) is also broken. This is called a distal ulna fracture.
Colles' fracture fracture of the lower end of the radius, the distal fragment being displaced backward. comminuted fracture one in which the bone is splintered or crushed, with three or more fragments. See illustration. complete fracture one involving the entire cross section of the bone. compound fracture open fracture.
