Introduction and Aims: Distal biceps ruptures are an uncommon injury. They represent approximately three percent of all biceps ruptures. Intervention was popularised by Boyd and Anderson who described a two-incision technique. Improved outcome has been achieved with stronger fixation allowing early mobilisation.

Method: All patients who underwent operative fixation of distal biceps ruptures by the senior two authors were identified. All patients were clinically reviewed at a minimum of six months from surgery. Functional outcomes scores in the form of Patient Rated Elbow Evaluation (PREE) and DASH scores were assessed. The operative technique utilised the Endobutton (Smith and Nephew) and is a substantial modification of that published by Bain,G et al.

Results: Thirty-one patients were identified. All patients were male with an average age of 47 years. Average delay to surgery was 24 days. There were no postoperative complications and no repeat ruptures. Thirty patients have returned Patient Rated Elbow Evaluation (PREE) forms with an average score of eight. Cybex testing demonstrates good return of strength when compared to the uninjured side.

Conclusion: Fixation of distal biceps ruptures using this modified Endobutton technique is a safe and effective method.
