Management of type IIB and IIIB olecranon fractures. Case series.

Objectives: to report and evaluate the functional outcome of plate fixation in comminuted olecranon fractures (Mayo types IIB and IIIB).

Method: 23 consecutive patients with comminuted fractures of the olecranon presenting to our unit Between Feb 2011 and Jan 2015, at a mean follow-up of thirty-six months. Main outcome measurements include radiographic healing, post-operative range of motion, complications, outcome score and patient satisfaction.

Results: Our study included thirteen females and ten males with a mean age of 55(18-97). Fourteen were Mayo type IIB and nine were Mayo type IIIB. Eighteen patients had no complications post-operatively with good outcome with mean oxford score of 45, full rotational ROM and mean flexion arc of 20-130°. Five patients had range of motion between 40-90° with full rotational ROM and mean oxford score of 24. Two patients out of five required metal work removal. No non-unions were noted in our series.

Conclusion: Plate fixation of complex olecranon fracture is an effective, reliable method of treatment with low risk of non-union. Restoration of a functional flexion arc of movement can be expected with application of correct technique.
