Introduction
 The pelvic girdle provides a sturdy foundation for the trunk and spine.
 The hip joint, or acetabular femoral joint , performs free range of movement like the shoulder joint.
McGraw-Hill
 The lower extremities depend on the hip joint to be relatively stable.

Bones
McGraw-Hill
 The head of the femur connects with the cup-shaped acetabulum of the pelvic girdle.
 Bony landmarks, the greater and lesser trochanter, provide attachments for many muscles spanning from the pelvic bones and even the vertebrae anteriorly.

Bones (cont.)
McGraw-Hill
 The pelvic girdle consists of the right and left pelvic bone joined together posteriorly by the sacrum ; inferior to the sacrum is the coccyx.
 The pelvic bones consist of three bones: the ilium, the ischium , and the pubis .

 Additional important bony landmarks include the ischial tuberosity of the posterior ischium and the linea aspera on the posterior femur.
 Anterolaterally,
Gerdy’s tubercle provides the insertion point for the iliotibial tract .

Joints
McGraw-Hill
 The pelvic bones join in the front to form the symphysis pubis , an amphiarthrodial joint.
 The sacrum is located between two bones and form the sacroiliac joint made up of strong ligaments.

McGraw-Hill
Joints (cont.)
 The hip joint is classified as an enarthrodial-type joint with a dense ligamentous capsule.

Nerves (cont.)
McGraw-Hill
 The femoral nerve innervates the anterior muscles of the thigh and provides sensation to the anterior and lateral thigh and medial leg and foot.
 The obturator nerve innervates the adductor as well as the obturator externus and sensation to the medial thigh .

Nerves (cont.)
McGraw-Hill
 The sciatic nerve is composed of the tibial nerve and common peroneal nerves .
 The sciatic nerve tibial division innervates the hamstrings and adductor magnus. Both nerves continue down the lower extremity to function the muscles of the leg and foot.
