Arthroscopic repairs of triangular fibrocartilage complex tears.

Technical advancements in arthroscopic wrist procedures have improved our knowledge of normal and abnormal intraarticular wrist function. Triangular fibrocartilage complex (TFCC) tears from trauma injuries are a common source of ulnar-sided wrist pain. Fortunately, the TFCC is a structure that can be evaluated and treated arthroscopically with results that are comparable to open surgical procedures. Successful arthroscopic repairs of TFCC tears depend on a coordinated team effort between perioperative nurses, orthopedic surgeons, nurse practitioners, and occupational hand therapists, as well as cooperation from patients and family members. This article reviews the anatomy and physiology of the TFCC, the biomechanics of the wrist and mechanisms of injury, and arthroscopic repairs of TFCC tears.
