Subpectoral Biceps Tenodesis Using an Expanding PEEK Device.

In this Technical Note, we describe a method of mini-open long head biceps subpectoral tenodesis. The implant used is a threadless expanding PEEK (polyether ether ketone) interference device that fixes the biceps tendon in a drill hole in the humerus under the inferior border of the pectoralis major tendon. The diameter of the drill hole varies between 6 and 8 mm depending on the width of the tendon. The procedure can be performed through a 3-cm incision centered on the inferior border of the pectoralis tendon. Based on our experience, it is a quick, safe, and reliable tenodesis procedure.
