As in this case, the linear probe demonstrated that the hypoechoic mass was, in fact, edematous intestine wall deep to the pectineus
muscle [Figure 1]b.
Nerve to pectineus arose from the femoral nerve within the abdomen in three plexuses.
When the branch to the pectineus nerve was present, it was the most medial branch off the femoral nerve in all but one specimen, where it was the second most medial branch to leave the compound femoral nerve after the sartorius nerve.
Distinct fascicles or groups of fascicles in each compound femoral nerve represented distal nerve branches of the femoral nerve (sartorius, pectineus, medial cutaneous, saphenous, vastus medialis, vastus intermedius, vastus lateralis, and rectus femoris).
We found fascicles from the pectineus nerve usually ventrally located but mixed with fascicles from vastus medialis and vastus lateralis nerves in specimen 2 (left side).
Ultrasound is useful in evaluating the following tendons about the hip: iliopsoas, rectus femoris, sartorius, tensor fasciae latae and iliotibial band, common adductor, pectineus
, distal rectus abdominis and conjoined tendon, gluteus medius, gluteus minimus, and common hamstring origin.
The femoral triangle is bounded superiorly by the inguinal ligament, medially by the adductor longus, laterally by the sartorius, and posteriorly by the iliopsoas, pectineus
and adductor longus muscles.
Pain was caused during palpation of the left pectineus, obturator externus, psoas and proximal rectus femoris.
The patient was diagnosed with left psoas contracture/ tendinopathy and a plan of management including active and passive stretching of left psoas and rectus femoris, manual facilitation of gluteus maximus, ART[R] of psoas, rectus femoris, obturator externus, sartorius and pectineus was proposed.

The sartorius muscle was detached from its proximal attachment, and the femoral triangle was dissected free to reveal the femoral vessels and their branches, the pectineus, and the adductor longus muscles.
The pectineus muscle was divided transversely 1 cm below its origin and turned toward the femur.
