ANT. ASPECT OF TIBIA & FIBULA
POSTERIOR ASPECT OF TIBIA & FIBULA
LIGAMENTS SACROTUBEROUS LIGAMENT SACROSPINOUS LIGAMENT EXTENDS bw med. Margin of ischial tuberosity and post.iliac spines Forms posterolateral boundary of outlet of pelvis SACROSPINOUS LIGAMENT Short thick band deep to sacrotuberous ligament. Attached to ischial spine laterally Sacrococcygeal juntion medially ISHIOFEMORAL LIGAMENT THESE LIGAMENTS CONVERT GREATER N LESSER NOTCHES INTO FORAMINA OF HIP BONE
STRUCTURES PASSING THROUGH GREATER SHIATIC FORAMEN FORMED By greater sciatic notch of hip bone and Sacrotuberous & sacrospinous ligaments. PROVIDES an exit from pelvis into gluteal region. The piriformis fills the foramen almost completely. Above the piriformis Sup. Gluteal nerve Sup. Gluteal vessels Below the piriformis Inf. Gluteal nerves Inf. Gluteal vessels Sciatic verve Post.Cutaneous nerve of thigh Nerve to quadratus femoris Pudendal nerve Internal pudendal vessels Nerve to obturator internus
STRUCTURES PASSING THROUGH LESSER SCIATIC FORAMEN PROVIDES an enterance into perineum from gluteal region. presence enables nerves n blood vesels that have left the pelvic through the greater sciatic foramen above the pelvic floor to enter the perineum below the pelvic floor.. Tendon of obturator internus Pudendal nerve Internal pudendal vessels Nerve obturator internus Origin of two gemelli muscles
