目的：探讨跟腓韧带（calcaneofibular ligament ，CFL ）本体感受器的数量、分布及其在踝关节运动中发挥的作用。方法选取10例膝上截肢患者跟腓韧带，将韧带分为近、中、远三段，切成20μm厚切片进行免疫组织化学染色，观察本体感受器类型和数量。结果 CFL及周围组织均存在本体感受器，Ⅱ型和Ⅲ型本体感受器数量显著多于Ⅰ型本体感受器（ P ＜0．001），韧带各部分间的本体感受器数量无明显差异（ P ＞0．05）。结论 CFL上本体感受器以Ⅱ型和Ⅲ型小体为主，Ⅱ、Ⅲ型本体感受器与运动觉和过度活动觉密切相关，其数量较多与踝关节稳定性密切相关。

Objective To explore the number ,distribution and functions of proprioceptor in calcaneofibu-lar ligament(CFL) .Methods CFLs from ten amputation cases were divided intoproximal ,central and distal segments and were cut into slices of 20μm .The slices were stained by immunohistochemical method to ob-serve the number and types of proprioceptors .Results Proprioceptors were found in calcaneofibular liga-ments and peripheral tissues .TypeⅡ and Type Ⅲ proprioceptors were found much more than Type Ⅰ(p< 0 .001) .No significant difference in proprioceptor density in the different parts of ligaments were found ( P >0 .05) .Conclusion Proprioceptors in calcaneofibular ligaments are mostly composed of Type Ⅱ and Type Ⅲ .Type Ⅱ and Type Ⅲ are closely correlated with the sensation of movement and over-activity . The number of proprioceptors is closely related to the stability of ankles .
