Traumatic laceration of the radial nerve following supracondylar fracture of the elbow. A case report.

Traumatic laceration of the median, ulnar, or radial nerve is an extremely rare complication of supracondylar fracture of the humerus in children. A recent review of the literature disclosed only two reported cases of a laceration involving the radial nerve; a third such injury in an 8-year-old boy is reported in the present paper. Traumatic neuropraxia of one or more of the three adjacent peripheral nerves is a more common complication of supracondylar fracture, with the great majority of these lesions responding to conservative treatment. Vascular compromise secondary to traumatic laceration of the brachial artery is a more frequently observed injury, with an incidence in some series as high as 10%. Clinical findings that suggest vascular injury, therefore, warrant a more aggressive approach, either by arteriography or surgical exploration.
