Fixation of Olecranon Fractures Using Plating System

ABSTRACT

PURPOSE: To evaluate the clinical and radiological outcomes of plate fixation for olecranon fractures which was difficult to be fixed firmly with tension band wiring alone. MATERIALS AND METHODS: From 1995 through 2008, 20 patients who underwent plate fixation of an olecranon fracture were included in this retrospective study. According to the Mayo classification, there were 3 type IIA fracture, 7 type IIB, and 10 type IIIB fractures. Clinical evaluation was done based on radiographic union of olecranon and measurements of range of motion at last follow-up. Disability of the arm, shoulder and hand (DASH) score and Mayo Elbow Performance score was used for evaluation of functional recovery. RESULTS: Union was achieved in 18 (90%) at an average of 5.6 months. The mean arc of elbow motion was 123degrees and the mean rotation arc was 81degrees. According to the MEPS, sixteen of twenty patients had a good or excellent outcome. The mean DASH score was 16.3. Most common complication was hardware irritation in 3 patients. CONCLUSION: Plate fixation is an effective treatment option for severe olecranon fracture pattern like comminuted fractures, Monteggia equivalent with unstable elbows and nonunions.
