Abstract: Objectives: To report and evaluate the functional outcome of plate fixation in comminuted olecranon fractures (Mayo types IIB and IIIB).
Method: 16 patients with comminuted fractures of the olecranon presented to our unit, were operated on with a locking Olecranon plate. Main outcome measurements included radiographic healing, postoperative range of motion, complications, outcome score and patient satisfaction measured at 1 year follow up.
Results: Our study included six females and ten males with a mean age of 48(18–67). Nine were Mayo type IIB and seven were Mayo type IIIB. Fourteen patients had no complications post-operatively with good outcomes with a mean oxford score of 44, full rotational ROM and mean flexion arc of 20-130 deg. Two patients had a range of motion between 40-90 deg with full rotational ROM and a mean oxford score of 28. No patients required hardware removal. No non-unions were noted in our series.
Conclusion: Plate fixation of complex olecranon fracture is an effective, reliable treatment method with a low risk of non-union. Restoration of a functional flexion arc of movement can be expected with the use of correct technique and early post-op mobilization.
