Abstract

Radiocarpal and intercarpal arthrodeses were simulated in 12 fresh cadaver wrists by means of external fixation. Range-of-motion measurements were made before and after simulated arthrodesis and used to calculate the contribution of the midcarpal and radiocarpal joints to wrist motion, as well as the residual wrist motion after limited intercarpal arthrodeses. Relative contributions to wrist motion were as follows: wrist flexion: radiocarpal (RC) joint 63%, midcarpal (MC) joint 36%; wrist extension: RC joint 53%, MC joint 46%. The wrist motion remaining after simulated arthrodeses was as follows: capitate-hamate: flexion (Flx) 98%, extension (Ext) 92%, ulnar deviation (UD) 96%, radial deviation (RD) 90%; scaphoid-lunate: Flx 97%, Ext 91%, UD 90%, RD 91%; scaphoid-trapezium-trapezoid: Flx 86%, Ext 88%, UD 67%, RD 69%; scaphoid-lunate-triquetrum: Flx 91%, Ext 82%, UD 86%, RD 70%; capitate-lunate: Flx 70%, Ext 59%, UD 89%, RD 79%; capitate-hamate-triquetrum: Flx 88%, Ext 79%, UD 88%, RD 81%; hamate-triquetrum: Flx 90%, Ext 85%, UD 89%, RD 94%; scaphoid-trapezium-trapezoid-capitate: Flx 85%, Ext 77%, UD 64%, RD 57%.

摘要

通过外固定在12个新鲜尸体腕关节上模拟桡腕关节和腕骨间关节融合术。在模拟关节融合术前和术后进行活动度测量，用于计算腕中关节和桡腕关节对腕关节活动的贡献，以及有限腕骨间关节融合术后的残余腕关节活动度。对腕关节活动的相对贡献如下：腕关节屈曲：桡腕（RC）关节占63%，腕中（MC）关节占36%；腕关节伸展：RC关节占53%，MC关节占46%。模拟关节融合术后剩余的腕关节活动度如下：头状骨-钩骨：屈曲（Flx）98%，伸展（Ext）92%，尺偏（UD）96%，桡偏（RD）90%；舟骨-月骨：Flx 97%，Ext 91%，UD 90%，RD 91%；舟骨-大多角骨-小多角骨：Flx 86%，Ext 88%，UD 67%，RD 69%；舟骨-月骨-三角骨：Flx 91%，Ext 82%，UD 86%，RD 70%；头状骨-月骨：Flx 70%，Ext 59%，UD 89%，RD 79%；头状骨-钩骨-三角骨：Flx 88%，Ext 79%，UD 88%，RD 81%；钩骨-三角骨：Flx 90%，Ext 85%，UD 89%，RD 94%；舟骨-大多角骨-小多角骨-头状骨：Flx 85%，Ext 77%，UD 64%，RD 57%。
