[Distal biceps tendon ruptures--experiences with soft tissue preserving reinsertion by bone anchors]

The repair of the distal biceps tendon rupture with bone anchors achieves excellent results. The important function of the M. biceps brachii as a powerful supinator and flexor can be reestablished and the soft tissue can be protected. We describe the repair of the rupture of distal biceps tendon by an anatomic refixation of the tendon to the tuberositas radii with bone anchors through a single anterior incision. In a four year period we treated eight patients with this technique. All patients were men with a mean age of 50 years. In each case the mechanism of injury was a single traumatic event with a large load on the flexed elbow. In average surgery was performed within five days and the patients stayed in the hospital for two days. Clinical follow up after almost two years showed no nerve damage or heterotopic bone formation. The range of motion and isometric muscle testing were almost symmetrical. All patients were able to return to preinjury activity level without any limitations.
