There are several modifications of the open LHBT tenodesis. The primary difference between them is in surgical implants, sites and technique, which are used for LHBT fixation to a humerus. This can be an interference screw or a suture anchor. With the interference screw threads of the screw itself attach the tendon to the walls of a bone tunnel. With the suture anchor, the tendon is attached to the bone anchor (which is also a screw without a head) by a double-looped suture (figure).
