A total of 20 patients scheduled for wrist arthroscopy, all with clinical signs of rupture to the triangular fibrocartilage complex and distal radioulnar joint instability, were tested pre-operatively by an independent observer for strength of forearm rotation. During surgery, the intra-articular pathology was documented by photography and also subsequently individually analysed by another independent hand surgeon. Arthroscopy revealed a type 1-B injury to the triangular fibrocartilage complex in 18 of 20 patients. Inter-rater reliability between the operating surgeon and the independent reviewer showed absolute agreement in all but one patient (95%) in terms of the injury to the triangular fibrocartilage complex and its classification. The average pre-operative torque strength was 71% of the strength of the non-injured contralateral side in pronation and supination. Distal radioulnar joint instability with an arthroscopically verified injury to the triangular fibrocartilage complex is associated with a significant loss of both pronation and supination torque.

共有20例计划进行腕关节镜检查的患者，均有三角纤维软骨复合体破裂及桡尺远侧关节不稳定的临床体征，术前由一名独立观察者测试前臂旋转力量。手术过程中，关节内病变通过摄影记录，并随后由另一名独立的手外科医生进行单独分析。关节镜检查显示，20例患者中有18例为三角纤维软骨复合体1-B型损伤。手术医生与独立评估者之间的评分者间可靠性显示，除1例患者外，在三角纤维软骨复合体损伤及其分类方面完全一致（95%）。术前平均扭矩力量在旋前和旋后时为未受伤对侧力量的71%。经关节镜证实的三角纤维软骨复合体损伤导致的桡尺远侧关节不稳定与旋前和旋后扭矩的显著丧失相关。
病例系列，IV级。
