Humerus Fractures After Open Subpectoral Biceps Tenodesis: Three Cases with 2-year Functional Outcome Data and Review of the Literature

CASE: The authors present 3 cases of humerus fracture after biceps tenodesis performed by 3 different surgeons with radiographs and outcome scores with a minimum of 30 months follow-up. Fractures occurred between 7 days and 4 months postoperatively and include 2 fractures where tenodesis had been performed with interference screw fixation and one fracture where tenodesis had been performed with a bicortical endobutton technique. CONCLUSIONS: These case reports highlight the risk of this complication in biceps tenodesis with bony fixation. The authors review the previously reported cases and relevant biomechanical studies that elucidate risk factors for humerus fracture and discuss alternative means to treat biceps tendon pathology.
