HIP & THIGH MUSCLES ATTACHMENT(ANTERIOR VIEW)

HIP & THIGH MUSCLES ATTACHMENT(POSTERIOR VIEW)

ATTACHMENTS ON ILIAC CREST

MUSCLE ATTACHMENT OF FEMOR

MUSCLES OF GLUTEAL REGION

ANT. ASPECT OF TIBIA & FIBULA

POSTERIOR ASPECT OF TIBIA & FIBULA

LIGAMENTS

SACROTUBEROUS 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
