Fracture of humerus during armwrestling: report of 5 cases.

Five cases of fracture of the humerus, including two types were treated over a period of twelve months. Three of these were simple spiral fractures of the lower third of the shaft. The other two were fractures of the medial epicondyle of the humerus. Two of the spiral fractures were complicated by radial nerve paresis and delayed union, and were operatively treated. The remaining three fractures were treated conservatively. These fractures are the result of a number of factors giving rise to violent torsional forces or avulsion forces. All five patients recovered well with respective treatment.
