Abstract:
Concomitant nonunion of an operatively treated fracture of the distal humerus and the olecranon osteotomy used for exposure is an unusual and complex situation which compromises ulnohumeral function on both sides of the joint. Operative treatment restored good elbow function in a series of six patients with this problem. An average of 110 degrees of ulnohumeral motion was restored, arthrosis was none (four patients) or mild (two patients) at an average follow-up of 50 months, and outcome measures documented good upper extremity specific (DASH) and general (SF-36) health status.
