You spot them immediately by the pectineus which is attached to them.
Branches supply the stifle and the adductor and pectineus muscles.
-- The obturator nerve, situated at first under the peritoneum, accompanies the obturator artery through the obturator foramen and gaining the muscles on the internal face of the thigh, terminates in the obturator externus, adductors, pectineus and gracilis, also giving twigs to the obturator internus (Strangeways).
From the femoral ring the canal extends down the thigh for an inch and a-half or two inches in a tapering form, supported by the pectineus muscle, and covered by the iliac part of the fascia lata.
The femoral vessels, K I, contained in their proper sheath, lie immediately beneath the iliac part of the fascia lata, in that angle which is expressed by Poupart's ligament, along the line C D above; by the sartorius muscle in the line C M externally; and by a line drawn from D to N, corresponding to the pectineus muscle internally.
An incision over the tumour, sufficient to allow the pectineus muscle to be exposed and divided, is necessary.
In this space the artery is crossed in front by the crural branch of the genito crural nerve, and behind by the branch to the pectineus from the anterior crural nerve; while the anterior crural nerve lies about half an inch to the outer side, imbedded between the iliacus and psoas muscles.
-- The upper fragment is carried forwards by the action of the psoas and iliacus internus, and at the same time everted and drawn outwards by the external rotator and glutei muscles, causing a marked prominence at the outer side of the thigh and great pain from the laceration of the muscles; the lower fragment is drawn upwards, by the rectus, biceps, semi-membranosus and semitendinous muscles, whilst its upper end is thrown outwards and its lower end inwards by the pectineus and adductor muscles; crepitation, preternatural
