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.
