Screw fixation of the olecranon after fracture or osteotomy.

For 10 years prior to the availability of the Olecranon Screw described in this article, oblique fixation using a regular Sherman bone screw was employed for displaced fractures (with a suitable fragment) by engaging the anterior ulnar cortex. Internal fixation was supplemented by a split for 3 weeks. The reason for a special olecranon screw is to eliminate the necessity for additional fixation and permit early motion. No instance of non-union or important restriction of motion or serious complication has been encountered.
