Palpation of soft tissue

Place the palpating finger a few centimetres distal to the anterior superior iliac spine and ask the patient to lift and abduct the extended leg.

Two structures can be felt and I or seen, one at each side of the finger, forming an inverted V (the lateral femoral triangle). The sartorius is the medial and the tensor fasciae latae the lateral muscle. Notice also the belly of the rectus femoris a few centimetres distal to the inverted V.The origin of the latter is felt deeply in the lateral femoral triangle, about 5 cm distal to the anterior superior iliac spine. Ask the patient to extend the knee, bend the hip to 60′ and add some resistance. This movement makes the belly of the muscle better visible. Palpate a bony prominence

– the inferior iliac spine
– from which the muscle originates.
