Background: The development of handicraft industry and increase of various such works that need a large amount of repeated wrist ulnar deviation strength, the incidence of ulnar impaction syndrome (UIS) is increasing, but the traditional simple ulnar shortening osteotomy has more complications. This study aimed to explore the early diagnostic criteria of UIS and its wrist arthroscopic treatment experience. Materials and Methods: 9 UIS patients were enrolled in this study. According to magnetic resonance imaging, X-ray and endoscopic features, the diagnostic criteria of UIS were summarized and the individualized treatment schedule was made. If the ulnar positive variance was less than 4 mm, the arthroscopic wafer resection was performed. If the ulnar positive variance was more than 4 mm, the arthroscopic resection of injury and degenerative triangular fibrocartilage complex and ulnar osteotomy were conducted. Results: In all patients, the wound healed without any complications. All patients returned to normal life and work, with no ulnar wrist pain again. One patient had wrist weakness. There was a significant difference of the wrist activity between the last followup and before operation (P < 0.05). According to the modified wrist function scoring system of Green and O'Brien, there were 6 cases of excellent, 2 cases of good and 1 case of appropriate and the overall excellent and good rate was 92.3%. Conclusion: In the treatment of UIS, the arthroscopy can improve the diagnosis rate, optimize the treatment plan, shorten the treatment cycle, with good treatment results.
