目的 对国人踝关节三角韧带深层胫距后韧带的远端止点进行观测，掌握更为详细的解剖学资料，为临床缝合锚钉修补或重建断裂的深层胫距后韧带提供解剖学参考。方法 30例成人尸体踝关节标本，对深层胫距后韧带的远端止点进行标记和解剖学观测。 结果 深层胫距后韧带是恒定存在的，而且是三角韧带中最为宽厚的1束，其近端止点在内踝后丘部及丘间沟，远端止点位于距骨内侧面后半部分，呈类圆形的不规则图形，远端止点附丽区面积为（111.74±19.97）mm²。 结论揭示了深层胫距后韧带的远端止点解剖学特点，为临床应用提供解剖学基础。

Objective To provide an anatomic evidence for the suture anchors treatment and reconstruction of deep posterior tibiotalar ligament ,the distal insertions of deep posterior tibiotalar ligament were measured. Methods We studied 30 cadaveric ankles. The insertions of deep posterior tibiotalar ligament were exposed, and their sizes and locations were measured and localized. Results Deep posterior tibiotalar ligament was a constant,and the widest and thickest deltoid ligament. It originated from posterior colliculus and,intercollicular groove of medial ankle, and inserted onto the postermedial talus.The distal insertions were not quadrangular. The areas of distal insertions were（111.74±19.97）mm². ConclusionThe anatomic characteristic of the distal insertion of the deep posterior tibiotalar ligament was revealed, which provides anatomical basis for surgery.
