Management of type IIB and IIIB olecranon fractures. Case series

Objectivesto report and evaluate the functional outcome of plate fixation in comminuted olecranon fractures (Mayo types IIB and IIIB).Method23 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.ResultsOur 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.ConclusionPlate 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.
