Distal biceps tendon rupture: a new repair technique in 14 patients using the biotenodesis screw.

BACKGROUND: Distal biceps tendon ruptures are uncommon injuries. Operative treatment has been shown to improve functional outcomes. A variety of surgical repair techniques have been described for distal biceps ruptures.

PURPOSE: The authors present their experience with a new technique to anatomically repair distal biceps tendon ruptures through a single-incision approach that they believe is a safe and reliable method of achieving repair.

STUDY DESIGN: Case series; Level of evidence, 4.

MATERIALS AND METHODS: Fourteen patients with 14 biceps tendon ruptures underwent a repair with a bioabsorbable Biotenodesis screw. All 14 patients underwent clinical assessment using the Mayo Elbow Performance Score, measurement of range of motion, and flexion strength testing. Mean follow-up was 29.1 months.

RESULTS: Three patients had a good result and 11 patients had an excellent result. The mean elbow flexion arc was 141.4 degrees (range, 125 degrees -155 degrees ; standard deviation, 7.19 degrees ) with no flexion contractures in the operated side compared with the unaffected elbow. All patients achieved an equal range of pronation/supination to the unaffected side. The mean flexion strength in the injured arm was 25.7 kg, compared with 26.9 kg in the uninjured side. No complications were noted about the elbow.

CONCLUSION: The authors believe this new technique gives a good functional outcome with reproducible results.
