Sacrospinous ligament Sacrospinous ligament The sacrospinous ligament (small or anterior sacrosciatic ligament) is a thin, triangular ligament in the human pelvis. The base of the ligament is attached to the outer edge of the sacrum and coccyx, and the tip of the ligament attaches to the spine of the ischium, a bone in the human pelvis. Its fibres are intermingled with the sacrotuberous ligament. The sacrotuberous ligament passes behind the sacrospinous ligament. In its entire length it covers the equally triangular coccygeus muscle, to which its closely connected. The presence of the ligament in the greater sciatic notch creates an opening (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. According to Jewish law, the sciatic nerve (Hebrew: Gid hanasheh) cannot be eaten, to commemorate Jacob's hurt in his struggle with an Angel. Sciatic nerve The sciatic nerve (also called "ischiadic nerve", "ischiatic nerve") is a large nerve in humans and other animals.
