Extra-articular low-velocity gunshot fractures of the radius and ulna.

Low-velocity gunshot fractures of the forearm are complex injuries and previously published studies have not emphasized the problems particular to these forearm lesions. Of the twenty-nine patients in this series, thirteen had peripheral nerve injuries, three had impending Voklmann's ischemia, and ten had delayed union or malunion of fractures after treatment by closed methods. Only thirteen had none of these problems. Eight patients had long-term disability resulting either from permanent nerve damage with loss of sensation or weakness of grip, or from significant loss of motion following delayed union or malunion. Although external fixation was adequate for undisplaced fractures, delayed (seven to fourteen days) primary internal fixation after the initial phase of wound healing had proved benign gave superior results in displaced fractures.
