FRACTURE OF THE TROCHLEA

Isolated fracture of the humeral trochlea is rare. Recent fracture cla ssification schemes do not specifically address this injury in regards to treatment. This case report describes an isolated fracture of the humeral trochlea treated with open reduction internal fixation. Radiog raphic union was present at 13 weeks, and at 20 weeks post-op, the pat ient had regained full elbow range of motion minus 5 degrees of termin al flexion. Open reduction and internal fixation can be performed with success if the trochlear fragment is large enough.
