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.
 The lower extremities depend on the hip
joint to be relatively stable.

Bones
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.)
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.

Bones (cont.)
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.

15-12
Joints
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.


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

Muscles (cont.)
The hip flexor iliopsoas muscle is
composed of the iliacus, the psoas major,
and the psoas minor.
 The posterior gluteal region contain the
gluteal maximus, gluteus medius, and
gluteus minimus.

Muscles (cont.)

The deep six lateral rotators are the piriformis,
obturator externus, obturator internus,
gemellus superior, gemellus inferior, and
quadratus femoris.
 The tensor fasciae latae attaches anteriorly and
laterally to abduct and flex the hip.

Muscles (cont.)
The thigh has three compartments. The
anterior compartment houses the
quadriceps; the rectus femoris and the
knee extenders vastus medialis, vastus
intermedius, and vastus lateralis.
 The sartorius runs superficial to the
quadriceps.

Muscles (cont.)
The posterior compartment contains
the hamstrings consisting of the biceps
femoris, the semitendinosus, and the
semimembranosus.

Nerves
The hip and pelvic girdle muscles are all
innervated from the lumbar plexus and
sacral plexus known as the lumbosacral
plexus.

Nerves (cont.)

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.)

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.
