Effective treatment of fracture-dislocations of the olecranon requires a stable trochlear notch.
Our goal with this study was to better define and characterize fracture-dislocations of the olecranon and to provide additional data regarding complications and elbow function after operative treatment. Twenty-six patients with fracture-dislocations of the elbow were reviewed retrospectively. Ten had anterior and 16 had posterior fracture-dislocations. Five of 10 patients with anterior injuries and all of the patients with posterior injuries had an associated fracture of the coronoid process of the ulna. One of 10 patients with anterior and 13 of 16 patients with posterior injuries had fracture of the radial head. Only one patient had a true dislocation of the ulnohumeral joint. In the other 25 patients the articular surfaces remained apposed. All 26 patients were treated operatively and followed up for at least 3 years (average, 6 years). The results were good or excellent in 21 of 26 patients according to the system of Broberg and Morrey. The five unsatisfactory results were related to inadequate fixation of the coronoid with subsequent arthrosis (three patients), proximal radioulnar synostosis (three patients), and a subsequent fracture of the distal humerus (one patient). Fracture-dislocations of the olecranon occur in anterior and posterior patterns with specific injury characteristics and pitfalls. The key to effective treatment is stable restoration of the trochlear notch.
