Distal biceps tendon reconstruction with tendoachilles allograft: a modification of the endobutton technique utilizing an ACL reconstruction system.

Abstract

Distal biceps tendon ruptures typically occur with biceps contraction against resistance with the elbow flexed at 90 degrees. Anatomic repair is the gold standard in active patients. Numerous surgical techniques are available; however, the Endobutton might offer several advantages. We describe a novel technique for chronic distal biceps reconstruction using a modification of the Endobutton technique with an anterior cruciate ligament (ACL) drill guide as well as tendoachilles allograft. The Endobutton technique might offer several advantages, including direct tendon-to-bone healing, less bony debris to limit heterotopic ossification, less heating of the bone, ease of use, a biomechanical superiority, and excellent clinical outcomes.
