Abstract
Triangular fibrocartilage complex (TFCC) injuries are a common cause of ulnar-sided wrist pain and may progress to persistent pain, instability of the distal radioulnar joint, and arthritis if left untreated. Diagnosis and management of these injuries requires a nuanced understanding of features pertinent to the clinical presentation, imaging, and arthroscopic findings for accurate management. Arthroscopic-assisted repair techniques have revolutionized surgical management, providing detailed visualization and facilitating the repair of TFCC injuries and associated pathologies with minimally invasive techniques. In this review, we discuss the anatomy of the TFCC, history and examination of ulnar-sided pathology, imaging findings, classification schemes, and surgical techniques for treatment of TFCC injuries. We also touch on pearls and pitfalls of the techniques, complications, and results of treatment.
