摘　　要：目的阐明前臂骨间膜韧带复合体结构的组成及精确的附着位置。方法解剖32具成人尸体前臂标本,辨认骨间膜所有的韧带,测量其附着部位与桡骨茎突或尺骨头尖端的距离,用该长度占整个尺桡骨长度的百分比来表示韧带的附着位置。结果前臂骨间膜包含五种韧带成分:中央带、附属带、远侧斜束、近侧斜索及背侧附属斜索。中央带桡骨起始处的远近端位置分别是桡骨总长度的55%和66%,尺骨是30%和42%。附属带桡尺骨附着处中心点的位置是桡骨38%及尺骨24%。远侧斜束尺桡骨附着处中心点的位置是尺骨16%、桡骨10%;近侧斜索是尺骨82%、桡骨78%;背侧附属斜索是尺骨65%、桡骨63%。结论本研究阐明了所有典型的前臂骨间膜韧带精确的附着位置,这些信息对骨间膜韧带的生物力学研究及骨间膜重建手术计划适当的移植位置是非常有用的。Objective To elucidate the composition and precise attachment location of the forearm interosseous membrane ligament complex. Methods Thirty-two adult cadaveric forearm specimens were dissected to identify all ligaments of the interosseous membrane, measure the distance between the attachment site and the radius styloid process or the tip of the ulna head, and express the attachment location of the ligament by the percentage of the length to the length of the whole ulna and radius. Results The forearm interosseous membrane consists of five ligament components: central ligament, accessory ligament, distal oblique tract, proximal oblique cord and dorsal accessory oblique cord. The distal and proximal positions of the radius origin of the central ligament were 55% and 66% of the total radius length, respectively, and 30% and 42% of the total ulna length. The central points of the radius and ulna attachment location were 38% of the radius and 24% of the ulna for the accessory ligament, 10% of the radius and 16% of the ulna for the distal oblique tract, 78% of the radius and 82% of the ulna for the proximal oblique cord, and 63% of the radius and 65% of the ulna for the dorsal accessory oblique cord. Conclusion This study elucidates the precise attachment location of all the typical forearm interosseous membrane ligaments. This information is very useful for the biomechanical study of the interosseous membrane ligaments and the appropriate transplantation location of the interosseous membrane reconstruction surgery.
