Few reports are found in the extant medical literature regarding the vastoadductor membrane. This membrane effectively creates a subcompartment within the subsartorial canal. The lower limbs of 16 embalmed adult cadavers were dissected to identify the vastoadductor membrane and note its measurements. A vastoadductor membrane was identified in all specimens and was derived from the medial intermuscular septum. This membrane connected the medial edge of the vastus medialis muscle to the lateral edge of the adductor magnus muscle. Membranes were all wider proximally and narrowed distally. The mean length of this structure was 7.6 cm. The mean width of the vastoadductor membrane at its proximal, midportion, and distal parts was 2.2, 1.7, and 0.5 cm, respectively. The mean distance from the anterior superior iliac spine to the proximal border of the vastoadductor membrane was 28 cm. The mean distance from the distal border of the membrane to the adductor tubercle was 10 cm. Seventy-five percent of specimens exhibited a fenestrated vastoadductor membrane. Branches of the saphenous nerve to the skin of the medial thigh pierced the vastoadductor membrane in 31% of specimens. Two specimens demonstrated branches derived from the branch of the obturator nerve that pierced this membrane en route to the skin of the medial thigh. Perforating venous branches from the great saphenous vein were identified in 22% of specimens. As compression of the femoral artery at the adductor hiatus is a well-recognized entity, the clinician may also try to explore potential compression of this vessel more proximally by an overlying vastoadductor membrane. The authors would also hypothesize that due to the interconnection between the adductor magnus and vastus medialis by the vastoadductor membrane that a potential synergy exists between the functions of these two muscles.
在现存的医学文献中，关于股收肌膜的报道很少。该膜有效地在收肌管内形成了一个子腔室。对16具防腐处理的成年尸体的下肢进行解剖，以识别股收肌膜并记录其尺寸。在所有标本中均识别出股收肌膜，其源自内侧肌间隔。该膜将股内侧肌的内侧边缘与大收肌的外侧边缘相连。膜在近端均较宽，在远端变窄。该结构的平均长度为7.6厘米。股收肌膜在其近端、中部和远端的平均宽度分别为2.2厘米、1.7厘米和0.5厘米。从髂前上棘到股收肌膜近端边界的平均距离为28厘米。从膜的远端边界到收肌结节的平均距离为10厘米。75%的标本显示股收肌膜有孔。隐神经至大腿内侧皮肤的分支在31%的标本中穿过股收肌膜。两个标本显示有源自闭孔神经分支的分支，该分支在通向大腿内侧皮肤的途中穿过此膜。在22%的标本中发现了大隐静脉的穿支静脉分支。由于收肌腱裂孔处的股动脉受压是一个公认的情况，临床医生也可以尝试探索该血管在更靠近近端处是否受到上方股收肌膜的潜在压迫。作者还推测，由于股收肌膜连接了大收肌和股内侧肌，这两块肌肉的功能之间可能存在协同作用。
