Complications
Failure rates for both arthroscopic debridement and repair of TFCC tears are increased in the ulnar positive wrist. Failure has been attributed to underlying degenerative TFCC and ulnocarpal pathology. Ulnar shortening osteotomy remains a viable treatment option for those with persistent pain, even in the setting of ulnar neutral or ulnar negative variance. Recurrent DRUJ instability secondary to suture rupture or ligament detachment may result in failure for patients to improve. A recent systematic review of 895 total cases found a reported complication rate of 4.7%. Commonly reported complications include injury to the dorsal sensory branch of the ulnar nerve and tendon injuries. More rare complications include ganglion cyst development, arterial injury, de Quervain tenosynovitis, stiffness, equipment-related burns, and fistulae formation.
