A new intramedullary fixation method for distal biceps tendon ruptures: a biomechanical study

Abstract

Various techniques have been described for distal biceps tendon reinsertion. Although high success rates have been reported, all current techniques have specific shortcomings, with complications such as heterotopic ossification, nerve damage, and gap formation. The purpose of the present study was to biomechanically evaluate a new intramedullary fixation device that might reduce the risk of posterior interosseous nerve lesions. We therefore compared the fixation strength of this new intramedullary button with an extramedullary placed classic extracortical button.
