Repair of Distal Biceps Tendon Ruptures Using a Suture Anchor and an Anterior Approach

Abstract

In a prospective study, eight consecutive patients with nine ruptures of the distal biceps tendon underwent repair through a single incision. All patients were satisfied with their clinical results and had full ranges of elbow and forearm motion. There were no radial nerve injuries and no radio-ulnar synostoses. Isokinetic testing, after correction for dominance, demonstrated a 6% strength deficit, but 7% higher endurance in the repaired extremity for the flexion-concentric test, and no strength deficit and 13% higher endurance for supination. The improved endurance is probably explained by initial reduced effort due to apprehension which minimized subsequent fatigue.
