Long term evaluation of repaired distal biceps brachii tendon ruptures

A long term evaluation was performed on 8 patients who had rupture of the distal biceps tendon repaired using the 2-incision technique. The length of followup ranged from 1 to 11 years with an average of 6 years. Goniometric range of motion and isokinetic strength testing were performed on all patients. All patients attained a full arc of elbow flexion and extension. Supination was diminished more than 30 degrees in 3 patients and pronation was diminished more than 30 degrees in 1 patient. Subjectively, 6 of 8 patients were completely satisfied with the function of their involved arm. Strength and work performed during repetitive exercise were regained to the expected normal levels in elbow flexion. Six of 8 patients continued to have less strength in supination of the injured arm than the uninjured arm. All 8 patients performed less total work with repetitive supination of the injured arm than the uninjured arm.
