Abstract：
Several studies have indicated that Camitz transfer for severe carpal tunnel does not adequately restore thumb opposition. The aim of this study was to determine whether modification of the distal insertion of the transferred palmaris longus tendon could provide more effective opposition. We used 12 fresh-frozen upper extremity specimens. For spatial analysis, we used a three-dimensional motion-tracking device. At 0 N and 5 N of traction force, the pronation angle was significantly larger for the modified procedure than for the conventional procedure. There was no significant difference in the palmar abduction angle between the two groups. The modified palmaris longus tendon insertion on the ulnar side of the thumb metacarpophalangeal joint provides more effective thumb pronation than conventional Camitz opponensplasty in a cadaver model. .
摘要：
多项研究表明，卡米兹转移治疗严重的腕管并不能充分恢复拇指相对。这项研究的目的是确定是否改变转移的掌长肌腱的远端插入可以提供更有效的反对。我们使用了12个新鲜冷冻的上肢标本。对于空间分析，我们使用了三维运动跟踪装置。在0N和5N的牵引力下，改良手术的内旋角度明显大于传统手术。两组手掌外展角度无明显差别。在尸体模型中，在拇指掌指关节的尺侧插入改良的掌长肌腱比常规的Camitz人工成形术提供了更有效的拇指内旋。.
