|
When treating a Monteggia fracture, it would be ideal to achieve reduction of dislocation while preserving the radial head. But if preservation of radial head is impossible, radial head replacement may be performed after removing the head. However, in patients who require head resection because it was impossible to replace the radial head, the load applied on the elbow is concentrated on the ulnohumeral joint. If a metal plate is used in this area to fix an ulnar shaft fracture, the proximal screw may act as a stress riser to make the area vulnerable to a fracture. We experienced cases of stress fracture in the olecranon of along the screw insertion due to the proximal screw acting as a stress riser, used in open reduction and metal plate fixation for ulnar shaft fractures in osteoporotic patients with Monteggia fracture who had the radial head removed or had nonunion after previous radial neck fracture. |
