【摘要】 目的 :观察手舟骨与月骨间的舟月骨间韧带的解剖学结构和分布特点 ,探讨其对舟月骨间关节稳定性的作用。方法 :采用 2 2只成人尸体标本 ,在解剖显微镜下观察舟月骨间韧带的大体形态、长度变化、与腕囊内韧带的关系和在舟月骨上的附着点的位置及宽度。结果 :舟月骨间韧带分成掌侧部、近侧部和背侧部 ,其掌背侧部以致密纤维结构为主 ,但近侧部显示有纤维软骨样成份。此韧带和桡舟头韧带、桡舟月韧带及腕背侧横韧带有联系 ,舟月骨间韧带对舟月骨间关节稳定性起作用 ,以掌背侧部的稳定作用为主。结论 :舟月骨间韧带结构特殊 ,对舟月骨间关节稳定性起决定性作用。更多还原

【Abstract】 Objective:To investigate morphologic features of scapholunate interosseous ligament (SLIL) of wrist and its role in scapholunate joint stabilization.Methods: Morphological features and attachment location and width of the ligament were studied on 22 adult cadaveric wrists under anatomic microscope.Results:The SLIL is composed of three parts: palmar part, proximal part and dorsal part.The palmar part and dorsal part mainly composed of compact connective tissue and fibrocartilage were found in proximal part.The SLIL connects with the radiocaphocapitate radioscapholunate and dorsal carpal ligaments.The palmar and dorsal parts of SLIL play an important role in stabilization of scapholunate joint.Conclusion:The SLIL has special structure and is the key structure for stability of scapholunate joint.更多还原
