Excursions of tendons around the scaphoid were measured in 6 fresh cadaver forearms to evaluate the role of the scapholunate interosseous ligament (SLIL) in wrist joint motion. Excursions of the extensor carpi radialis longus (ECRL) and brevis (ECRB) tendons and the flexor carpi radialis (FCR) tendon were continuously recorded during wrist flexion, extension, and radial and ulnar deviation. Tendon excursions were measured in the intact wrists and after complete sectioning of the SLIL. Tendon excursions were altered significantly in the major ranges of wrist motion after SLIL sectioning. After ligament sectioning, excursions of the ECRL and ECRB tendons increased significantly in wrist flexion and extension. Excursions of the FCR tendon increased significantly during wrist extension and ulnar deviation. These findings support the concepts that integrity of the SLIL plays an important role in wrist function and that injury of the ligament may cause clinical problems.
在6具新鲜尸体的前臂中测量了绕舟骨的肌腱移位情况，以评估舟月骨间韧带（SLIL）在腕关节运动中的作用。在腕关节屈曲、伸展以及桡偏和尺偏过程中，连续记录桡侧腕长伸肌（ECRL）和桡侧腕短伸肌（ECRB）肌腱以及桡侧腕屈肌（FCR）肌腱的移位情况。在完整腕关节以及完全切断SLIL后测量肌腱移位。切断SLIL后，在腕关节运动的主要范围内肌腱移位发生了显著改变。韧带切断后，ECRL和ECRB肌腱在腕关节屈曲和伸展时的移位显著增加。FCR肌腱在腕关节伸展和尺偏时的移位显著增加。这些发现支持了以下观点：SLIL的完整性在腕关节功能中起重要作用，并且该韧带损伤可能导致临床问题。
