Kinesiology Of Hip Joint & Pelvic Girdle

15-2
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.

The SIJs are unique in that both the structure and function of these joints change significantly from birth through adulthood

What is the Symphysis Pubis? Secondary Cartilaginous Joint. A Thin Layer of Hyaline Cartilage Cover the Bone. This Cartilage is Joined to the Opposite Cartilage by a
Fibrocartilage Interpubic Disc. Two Ligaments Support the Joint:
1) Superior Pubic Ligament2) Arcuate Pubic Ligament
The anterior portion of the joint is reinforced by aponeurotic expansions from a number of muscles that cross the joint
No Normally Movement Pathology:
Slipping of one pubic Slipping of one pubic to other (Osteitis Pubis)to other (Osteitis Pubis)

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.

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.

The Hip Joint
Type: Synovial (Ball & Socket)Articular Surfaces: head of femur & acetabulum
15-29Articular surfaces: 1- Acetabulum has: - C- shaped articular surface = lunate surface, Acetabular fossa,- Acetabular notch -----► converted into acetabular foramen by
transverse ligament of the acetabulum- - Labrum acetabulare deepens the acetabular cavity.- 2- Head of femur
15-30
Capsule & Synovial Membrane:
15-31
Ligaments:
1- Ilio-femoral lig.: Y- shaped, strong, attached between AIIS and both ends of trochantric line. Prevents hyper-extension.
2- Pubo-femoral lig.:Triangular in shape, supports the inferomedial part of the joint, attached between ilio-pubic eminence and the capsule. Prevents hyper-abduction.
3- Iscio-femoral lig.: from ischium to the back of the capsule. It becomes tense in medial rotation.
4- round ligament of the head of femur: Inside the joint, between head of femur to acetabular notch and transverse lig., carries blood supply to head of femur.
15-32
Relations of the hip joint: Anteriorly:Pectineus, Iliopsoas, RF
(straight head), femoral vessels.
Laterally:Tensor fascia latae, gluteus
minimus & medius.
Posteriorly:Piriformis, obturator
internus, 2 gemelli, quadratus femoris, sciatic nerve.
Above:RF (reflected head), gluteus
minimus.
Below:Obturator externus.
15-33
Stability of the hip joint:
The hip joint is very stable joint due to:1- The head of femur fits accurately to the
acetablum.2- The three strong ligaments outside the capsule.3- The surrounding strong muscles.
Hip dislocation is usually posterior as in car accidents. It occurs with no fracture of the acetabulum (if the hip is flexed and adducted) or with fracture acetabulum (if the hip is flexed and abducted). The sciatic nerve may be injured in posterior hip dislocation.

15-55
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.
