In addition to the obturator nerve and vessels a fat body in the obturator canal is found in the majority of cases investigated. The fat body, small and isolated in newborns, is part of the subperitoneal mass of fat and loose areolar tissue in adults. In the 2 cases of obturator hernia the fat body has no connection with the peritoneum which constitutes the sac of the hernia. A strong fibrous cord running from the urinary bladder to the fat body of the obturator canal is observed in 46 cases. In 5 of these the cord causes a small pouch in the wall of the bladder.
除闭孔神经和血管外，在大多数被研究的病例中，闭孔管内还发现有脂肪体。脂肪体在新生儿中较小且孤立，在成人中是腹膜下脂肪和疏松结缔组织团块的一部分。在2例闭孔疝病例中，脂肪体与构成疝囊的腹膜无连接。在46例病例中观察到一条从膀胱延伸至闭孔管脂肪体的坚韧纤维索。其中5例中，该纤维索在膀胱壁上形成一个小囊袋。
