Abstract:

BACKGROUND: Due to the lack of understanding of the pathogenesis, ulnar impaction syndrome often referred to as carpitis, which delays the treatment of patients and causes severe carpal dysfunction.

OBJECTIVE: To retrospectively analyze the effect of arthroscopy combined with 2.7 mm titanium osteotomy plate fixation for treating the ulnar impaction syndrome.

METHODS: From March 2017 to September 2019, 12 patients with ulnar impaction syndrome were treated in the Department of Wrist, Sichuan Provincial Orthopedics Hospital. All patients received arthroscopy combined with 2.7 mm titanium osteotomy plate fixation to repair the intercarpal ligament, articular cartilage damage, and trigonal fibrocartilage complex. Ulna variation value, visual analogue scale score, modified Mayo score were compared preoperatively and 1 year postoperatively.

RESULTS AND CONCLUSION: (1) All the 12 patients were followed up after the operation, and bone healing was achieved. The healing time was 5-11 months, with an average of 6 months. (2) The ulna variation was (3.3±1.3) mm preoperatively, and (-0.4±0.6) mm postoperatively. The modified Mayo score was (59.2±10.6) preoperatively and (78.3±11.6) 1 year postoperatively. The effect was excellent in seven patients, good in four patients and fair in one patient. Visual analogue scale score was (5.2±0.7) preoperatively and (3.2±2.5) 1 year postoperatively. The pain was completely relieved in nine patients after surgery and significantly relieved in two patients. There were significant differences in the above indexes before and after operation (P < 0.05). (3) It is confirmed that wrist arthroscopy can clearly diagnose the ulnar impaction syndrome and the combination with 2.7 mm titanium osteotomy plate can save the operation time, reduce the rate of bone nonunion, relieve the wrist pain and improve the function of the wrist, which is conducive to early functional exercise and satisfactory effect.
