Distal biceps tendon tears in women.

HYPOTHESIS: Is the presentation and outcome of surgical treatment of distal biceps tendon tears different in women than men?

MATERIALS AND METHODS: From 1999 to 2008, 15 cases of distal biceps tendon tears in 13 female patients were treated surgically at a single institution. Mean age was 63 years (range, 48-79 years). A retrospective review evaluated patient presentation, diagnosis, and treatment. Postoperative outcomes were assessed by physical examination, a patient satisfaction survey, the American Shoulder and Elbow Surgeons (ASES) elbow assessment form, and the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire.

RESULTS: Two-thirds of the tears were in the dominant arm, of which 7 resulted from a single injury, and 8 reported insidious onset of symptoms. All patients presented with pain in the antecubital fossa. A distinct cystic mass was palpable in 6. Of the 15 cases, 13 were partially detached, 1 was completely detached, and 1 was weakly attached. Fourteen regained full strength, and all had nearly complete range of motion. Mean follow-up was 46 months (range, 2-117 months). Eleven completed a postoperative patient satisfaction survey, ASES elbow, and DASH questionnaire. Mean scores were 95 (range, 58-100) for ASES and 7 (range, 0-43) for DASH. The only complication was a transient lateral antebrachial cutaneous nerve sensory palsy.

DISCUSSION: Distal biceps tendon tears in women present at an advanced age with no history of an acute injury. They are frequently associated with a cystic mass and have a predominance of partial tears.

CONCLUSIONS: Distal biceps tendon tears in women present differently than in men. The tears are rarely complete and they respond well to surgical repair.
