Distal biceps tendon rupture operated on with the Boyd-Anderson technique: follow-up of 9 patients with isokinetic examination after 1 year.

We operated on 9 patients for distal biceps tendon rupture using the Boyd-Anderson technique. All patients were re-examined after at least 1 year using a questionnaire, radiographs, motion measurements and isokinetic testing. 2 patients had temporary radial nerve dysfunction and 7 patients had diminished forearm rotation. Elbow flexion strength was reduced by median 13% and supination strength by 19%. We think the Boyd-Anderson technique can be recommended, but slightly reduced strength and forearm rotation must be expected.
