The hip joint receives sensory innervation from branches of the femoral, obturator, superior gluteal, and sciatic nerves, as well as the nerve to quadratus femoris
(49) Generally, the anteriormedial portion of the capsule is innervated by the branches of the obturator nerve, anterolateral capsule branches of the femoral nerve, posteromedial joint from branches of the sciatic nerve, and/or nerve to quadratus femoris
, superolateral (posterior and anterior) from branches of the superior gluteal nerve.
From an anatomical point of view, HVLIA should be particularly useful for THA because the articular and cutaneous sensory supply of the hip region is complex and may extend from T12 (subcostal nerve) to S1 (proximal sciatic branches including the nerve to quadratus femoris
and superior gluteal nerve).
