Partial resection of the distal ulna (wafer resection) has been used to treat patients with symptomatic tears of the triangular fibrocartilage complex or mild ulna impaction syndrome. In this procedure, the distal 2 to 4 mm of the distal ulnar head is resected while preserving the ulnar styloid process and the ligaments attached to it. The triangular fibrocartilage is debrided, repaired, or partially excised as necessary. The procedure is contraindicated if there is more than 4 mm of positive ulnar variance. Thirteen wafer resections of the distal ulna were performed in 12 patients. All had good to excellent results after a minimum follow-up of 1 year. Wafer resection has specific advantages and avoids many of the potential complications of distal ulna recession and ulnar head resection for patients with the conditions described. The procedure is not indicated if instability or degenerative arthritis of the distal radioulnar joint is present or if there is carpal instability.
尺骨远端部分切除术（薄片切除术）已被用于治疗有症状的三角纤维软骨复合体撕裂或轻度尺骨撞击综合征的患者。在此手术中，切除尺骨远端头的远侧2至4毫米，同时保留尺骨茎突及其附着的韧带。必要时，对三角纤维软骨进行清创、修复或部分切除。如果尺骨正向变异超过4毫米，则该手术为禁忌。对12例患者进行了13次尺骨远端薄片切除术。所有患者在至少随访1年后均取得了良好至极佳的效果。对于所述病情的患者，薄片切除术具有特定优势，且避免了尺骨远端退缩和尺骨头切除术的许多潜在并发症。如果存在下尺桡关节不稳定或退行性关节炎，或存在腕关节不稳定，则不建议进行该手术。
