A biomechanical study was performed on fresh cadaver forearms to investigate the role of the scapholunate interosseous ligament in carpal stability. Scaphoid and lunate motion and radiocarpal and ulnocarpal pressure patterns were continually monitored while the wrist was moved physiologically. Prior to ligament sectioning, it was found that the position of the scaphoid and lunate were dependent on both the wrist position and the direction of wrist motion. Sectioning the scapholunate interosseous ligament caused increased scaphoid flexion, scaphoid pronation, and lunate extension. Pressure in the radiocarpal and ulnocarpal joint was redistributed following ligament sectioning. These findings support the clinical impression that the scapholunate interosseous ligament is an important stabilizer of the scaphoid and lunate.
对新鲜尸体的前臂进行了一项生物力学研究，以探讨舟月骨间韧带在腕关节稳定性中的作用。在腕关节进行生理性活动时，持续监测舟骨和月骨的运动以及桡腕关节和尺腕关节的压力模式。在切断韧带之前，发现舟骨和月骨的位置既取决于腕关节的位置，也取决于腕关节运动的方向。切断舟月骨间韧带会导致舟骨屈曲增加、舟骨旋前和月骨伸展。切断韧带后，桡腕关节和尺腕关节的压力重新分布。这些发现支持了临床印象，即舟月骨间韧带是舟骨和月骨的重要稳定器。
