Bone suture anchors in hand surgery.
The recent development of small bone suture anchors has created potential applications in reconstructive surgery of the hand and wrist. A combined laboratory and clinical study was devised to evaluate their use. 16 paired fingers (32 in all) from eight cadaveric hands were disarticulated at the MP joint with a 10 cm tail of FDP tendon. The FDP insertion was released in all specimens. In 16 fingers reinsertion was performed with the classic Bunnell technique; in the paired 16 fingers, the repair utilized Acufex 2 mm anchors. There was no significant difference between the two groups regarding load-to-failure at approximately 40 Newtons. The mean stiffness of the anchor repairs was significantly greater than the Bunnell repairs. 19 consecutive patients were prospectively enrolled with a tendon or ligament repair of the hand or wrist using bone anchors. The average age was 41 years and the average length of follow-up was 24 months. All repairs were stable at the time of follow-up. Bone anchors were simple to insert, required less dissection and surgical time than the Bunnell technique and appeared to be reliable in both laboratory and clinical settings.
