Limitations of the present study include that we arbitrarily selected the NEP of the adductor magnus muscle branch as an example, and we did not describe NEPs for the obturator and femoral muscle nerve branches of our two cadavers.
1 = gracilis muscle branch of the obturator nerve; 2 = adductor longus muscle branch; 3 = adductor brevis muscle branch; 4 = adductor magnus muscle branch; 5 = pectineus muscle branch; 6 = femoral nerve trunk.
Then it passes anterior to the adductor magnus muscle, dividing into branches to adductor magnus and occasionally the adductor brevis.
1,2,23) In our study, we have described the possible sites of entrapment of the posterior division by the branches of the obturator and medial circumflex femoral vessels as they cross the posterior division of the obturator nerve at the obturator foramen and anterior to the proximal part of the adductor magnus muscle.
