Arthroscopic Reduction and Percutaneous Fixation of Scaphoid Fracture and Nonunion / 대한정형외과학회잡지

ABSTRACT

PURPOSE: To analyze the results of an arthroscopic reduction and percutaneous fixation of scaphoid fracture and nonunion. MATERIALS AND METHODS: Fourteen scaphoid fractures or nonunion patients were analyzed clinically. There were 13 men and 1 woman, with a mean age of 30 (14-45) years. The average follow-up time was 13 months (12-18). Three cases had delayed union, 5 cases had nonunion and 6 cases had a fracture. After fluoroscopic reduction and an arthroscopic examination, the scaphoid was fixed with an Acutrak screw or K-wire percutaneously. The serial radiographs were checked by 2 weeks to confirm the bony union. The Mayo wrist score and DASH were used to assess the functional result at the final follow up. RESULTS: Bony union was acquired in 13 cases in a mean time of 8 weeks. The mean Mayo wrist score was 86 points (60-100) with 7 excellent, 4 good, 2 fair and 1 poor case. The mean DASH was 11.1 points (0-63.3). CONCLUSION: In scaphoid fracture and delayed union, good results could be obtained by an arthroscopic reduction and percutaneous fixation. However, in scaphoid nonunion, this technique should only be used in selected cases.
