隐神经收肌管段的应用解剖学

Anatomical study of adductor canal segment of saphenous nerve

在80侧成人下肢标本上观察了隐神经及其髌下支穿Hunter's管(收肌管)前壁的类型。其中隐神经除有93.8％穿该管前壁腱板浅出外,尚有6.3％未穿该管前壁腱板。神经穿出处之裂孔按形态分为3种:裂隙形(隐神经为74.7％;髌下支为65.0％)、近圆孔形(隐神经为14.7％;髌下支为20.0％)、狭窄形(隐神经为为10.7％;髌下支为15.0％。并测量了神经穿出点的位置距Hunter's管前壁腱板上缘的长度、裂孔的长度和横径,为临床探讨隐神经卡压症的病因和治疗提供应用解剖学资料。

On 80 adult lower limbs the saphenous nerve and its infrapatellar branch were found to pass tnrough the aponeurotic lamina of anterior wall of the adductor canal in 75 cases ( 93.8% ). The orifice at the lamina is classified into 3 types by its shape: the hiatus type(saphenous nerve 56 cases and infrapatellar branch 13 cases) ; the round type(11 and 4 respectively) and the slit type(8 and 3). Morphologic measurements of the orifice may provide anatomical basis for etiology and treatment of saphenous nerve entrapment.
