摘要
目的探讨产生腘窝囊肿的解剖因素。方法对25侧成人膝关节标本进行解剖:a)观察半膜肌与腓肠肌内侧头滑液囊(gastrocnemius-semimembranosus bursa,GSB)是否存在,GSB与膝关节滑膜囊的关系;b)是否存在GSB与膝关节滑膜囊的通道口;c)向关节腔内注射生理盐水,观察当关节腔内压力增大后,生理盐水是否向GSB内外流。结果 a)所有标本均存在GSB,与膝关节滑膜腔相通占40%(10/25),其他均存在与膝关节滑膜腔的薄弱区;b)膝关节腔内压力增大时关节液向GSB内外流。结论正常人膝关节存在形成腘窝囊肿的解剖基础。
Objective To explore the anatomical factor of the producing the popliteal cysts.Methods 25 adult knee-specimens were dissected and measured.a）To observe whether there is the gastrocnemius semimembranosus bursa（GSB）,and the relationship of GSB and knee articular cavity;b）whether there is a channel between GSB and knee articular cavity;c）inject physiological saline into joint,and observe whether physiological saline flowing to GSB as articular cavity pressure rising.Results a）There is GSB in every specimen,40%specimens（10/25） Communicates with knee articular cavity by a channel,and there is a weak area in every other specimen;b）Joint fluid flowing to GSB as articular cavity pressure rising.Conclusion There is anatomical basis forming popliteal cyst in normal knee.
