Abstract
The treatment of choice for proximal radial head fractures remains controversial. The goal of any treatment for an intra-articular fracture must be the complete restoration of the joint and its function. Nonoperative treatment leads to full motion in cases of less than 1-2 mm of fracture displacement. Resection of the radial head can be recommended only for very comminuted fractures. All other fracture types should be treated by open reduction and internal fixation. Our own personal follow-up observation of 19 patients who had surgical intervention demonstrated restoration of elbow function after an average follow-up time of 11.7 months. Five patients had a slightly restricted range of motion of less than 10 degrees extension and flexion as well as less than 8 degrees pronation and supination, without signs of arthritis. Because complications were minimal, we recommend internal fixation of displaced proximal radial head fractures to restore the anatomic function of the elbow. This is especially true in cases with accompanying proximal ulna fractures and/or ruptured collateral ligaments of the elbow joint and/or disruption of the distal radio-ulnar joint.
