Long Biceps Subpectoral Tenodesis With Suspensory Button and Bicortical Fixation.

Abstract

Tenodesis of the long head of the biceps (LHB) tendon has long been recognized as a valid alternative to address pathologic conditions of this tendon. However, the location and type of fixation is still a matter of discussion, because common complications associated with this procedure include failure of the repair, persistent pain, reaction to the fixation device, cosmetic deformity, and fracture. The authors describe a method of subpectoral LHB tenodesis that aims to preserve bone stock and allows a strong, easy, and reproducible type of fixation with a minimal approach. LHB tenotomy is performed arthroscopically in a standard fashion, and the tenodesis is completed with bicortical fixation in the humerus using a knotless suspensory button with an appropriate pusher originally developed for another purpose. Magnetic resonance imaging showed a safe distance between the implant and important vasculonervous structures. In the cases where subpectoral fixation is chosen, this method seems to offer additional safety as a result of the minimal amount of bone removed and the very small size of the implant.
