11- Hip joint, Gluteal region, Posterior thigh Flashcards
What type of joint is the hip joint?
Synovial ball and socket joint
Where does the head of the femur sit?
In the Acetabulum
What deepens the acetabulum and acts as a vacuum for the head of the femur?
The acetabular labrum and the femoral ligament
What is the function of the joint capsule?
Connects the acetabulum and the neck of the femur helping to strengthen the joint.
How do the ligaments help to increase the stability and strengthen the joint?
They tighten in extension and loosen in flexion
What are the 3 ligaments that join the femur to the pelvic girdle?
Iliofemoral ligament
Pubofemoral ligament
ishiofemoral ligament
Iliofemoral Ligament (articulation/what does it do?)
Comes from the anterior-inferior ileac spine.
The strongest of the 3 ligaments.
Prevent hyperextension.
Pubofemoral ligament (articulation/what does it do?)
Comes form the pubis
Prevents overabduction
Ishiofemoral ligament (articulation/what does it do?)
Comes from the ishium
Weakest of the 2 ligaments
What causes osteoarthritis of the hip?
Wear and tear of the articulate cartilage
What are some symptoms of osteoarthritis of the hip?
Stiffness of the hip and limited range of movement
How many muscle are in the gluteal region?
4
What are the muscles of the gluteal region?
Gluteus Maximus
Gluteus Medius
Gluteus Minimus
Tensor Facia Lata
Gluteus Maximus (articulation/what does it do?)
Powerful extensor of the hip
Originates form the posterior third of the ileum and inserts onto the iliotibial tract and the gluteal tuberosity.
Gluteus Medius and Minimus (articulation/what does it do?)
Abduct at the hip and also medially rotates the thigh.
Both originate from the ileum and insert onto the greater trochanter
