Hip bone portion. The inferior pubic ramus is thin and flat. It passes laterally and downward from the medial end of the superior ramus. It becomes narrower as it descends and joins with the inferior ramus of the ischium below the obturator foramen.

Sciatic nerve with sciatic nerve decompression by resection of fibrovascular scar bands, piriformis tendon release, obturator internus, or quadratus femoris or by hamstring tendon scarring." Signals from the sciatic nerve and its branches can be blocked, in order to interrupt transmission of pain signal from the innervation area, by performing a regional nerve blockade called a sciatic nerve block.
