Abstract: A distal biceps tendon repair device is disclosed. The device allows for anatomically correct biceps tendon repair using a single incision anterior approach without the risk associated with a double incision posterior approach. The distal biceps tendon repair device eliminates the necessity of cutting supinator muscle and greatly reduces the risk of contact or damage to vital structures such as arteries or nerves. The device has a bone drill guide mechanically coupled to a cannulated bone hook. A retrieval wire passes through the cannulated bone hook to grasp a suture or suture guide that has passed through a cannulated drill bit retained by the bone drill guide. The retrieval wire brings the suture through the cannulated bone hook, thus bringing the suture through and around the bone for subsequent anatomically correct attachment and placement of sutures used to reattach the distal biceps tendon to the bone.
