The medial approach to the hip gives excellent exposure to the insertion of the psoas tendon on the lesser trochanter

The medial approach to the hip gives excellent exposure to the insertion of the psoas tendon on the lesser trochanter. The medial femoral circumflex artery is at risk when performing a psoas release with this approach.
The medial approach to the hip involves utilizing the interval between adductor longus and gracilis, then adductor brevis and magnus in order to arrive at the lesser trochanter, psoas tendon, and hip capsule. The medial femoral circumflex artery branches off the profundus femoris (~85%) or femoral artery (15%) and then wraps posterior to the iliopsoas tendon before traveling posterior to the femoral neck to supply the femoral head.
