Abstract
Ninety-six wrists (56 right and 40 left) in 96 patients (36 males and 60 females, mean age 38, range 15-77 years) underwent repair of ulnotriquetral ligament split tears between 2007 and 2016. Mayo wrist scores, visual analogue scale pain scores, and objective measures including grip strength and range of motion were obtained. Patients were assessed after a mean follow-up of 21 months (range 6-112 months). Ulnotriquetral split tear repair resulted in substantial improvements in pain and function. The mean Mayo wrist score improved from 57 preoperatively to 81 postoperatively, with 84% of patients achieving a good or excellent outcome. Pain scores decreased from 5.8 to 1.2. Grip improved from 25 kg to 29 kg. There was no significant change in range of motion of the wrist. Complications were noted in eight patients, with three experiencing continued pain, four with dysaesthesia of the dorsal sensory ulnar nerve, and one superficial infection. Arthroscopic ulnotriquetral split tear repair significantly reduced pain and improved Mayo wrist scores. Level of evidence: IV.
