REASONS FOR PERFORMING STUDY: Previous olecranon fracture reports contain a small proportion of type 1b fractures, with only a few repaired by tension band plate fixation. OBJECTIVES: To evaluate subject details, history, clinical findings and outcome of type 1b olecranon fractures in a large group of horses treated by tension band plate fixation. METHODS: Medical records of 77 horses diagnosed with an olecranon fracture were reviewed. Twenty-four horses (31%) were classified as having type 1b olecranon fractures. Clinical details and follow-up results (4-128 months post operatively) were recorded. RESULTS: Treatment included open reduction and internal fixation using a narrow dynamic compression plate (n = 20), conservative therapy (n = 2) and euthanasia (n = 2). Long-term follow-up was available for 16 plated horses. Four were sound and in training and 9 were sound and performing athletically. Articular surface involvement, comminution, open status or removal of anconeal process fragments did not appear to affect prognosis or soundness. CONCLUSIONS: Internal plate fixation provides an excellent prognosis for an animal capable of athletic performance. POTENTIAL RELEVANCE: Describing tension band plate fixation and results offers a method of fracture repair that will improve the treatment and prognosis for type 1b olecranon fractures.
