Novel Triple-Loop Technique for Suturing TFCC Injuries without Transosseous Tunnel.

Abstract

Injuries to the triangular fibrocartilage complex (TFCC) are the most common cause of ulnar-sided wrist pain. As deepening of the research on the function and role of the TFCC, various treatment methods have emerged. Surgical treatment is often required for TFCC injuries that do not respond to conservative therapy. Currently, suturing techniques for TFCC injuries primarily include intra-capsular and transosseous tunnel suture techniques. However, traditional intra-capsular suturing has limited effectiveness for deep tears with a foveal footprint contact, while transosseous tunnel techniques pose problems such as difficulty in locating tunnels and ulna fracture. We have developed an improved triple-loop technique for treating Palmer IB-type TFCC injuries. This technique allows for suturing of both the deep and superficial layers of the TFCC without the need for a transosseous tunnel. Clinical follow-up results show that this is a safe, effective, and simple surgical method for treating TFCC injuries. In this article, we also discussed the comparison between the triple-loop surgical approach and other commonly used surgical approaches.
