摘要
目的探讨腘窝囊肿形成的解剖因素。方法对30个成人膝关节标本进行解剖:(1)观察半膜肌与腓肠肌内侧头滑液囊(GSB)是否存在,GSB与膝关节滑膜囊的关系;(2)是否存在GSB与膝关节滑膜囊的通道口;(3)向膝关节腔内注射生理盐水,观察当关节腔内压力增大后,关节内液体是否向GSB内外流。结果 (1)所有标本均存在GSB,40%(12个)标本的GSB与膝关节滑膜腔相通,其余60%(18个)均存在与膝关节滑膜腔相关联的薄弱区;(2)当膝关节腔内压力增大时关节液流向GSB内。结论半膜肌与腓肠肌内侧头滑液囊(GSB)是形成腘窝囊肿的解剖基础。
Objective To explore the possible anatomic factors on forming the popliteal cysts.Methods 30 adult knee-specimens were dissected and measured.（1）To observe the occurrence of the gastrocnemius semimembranosus bursa（GSB）,and explore the relationship of GSB and knee articular cavity;（2） To dissect and observe the channel between GSB and knee articular cavity;（3）To inject physiological saline into joint,and observe whether physiological saline reached to GSB as the result of articular cavity pressure rising.Results （1） GSB was observed in all specimens,and 40%（12 specimens） GSB communicated with knee articular cavity by a channel.（2） Joint fluid appered in GSB following the increased articular cavity pressure.Conclusions The gastrocnemius semimembranosus bursa is anatomical basis for forming popliteal cyst.
