Hip Flashcards
Type of joint is the hip joint
Synovial, multi axial, ball and socket
Ligaments in anterior and posterior hip joint.
Anterior = iliofemoral + pubofemoral
Posterior = ischiofemoral + inguinal ligament
Origin and insertion of inguinal ligament
Origin = ASIS
Insertion = pubic tubercle
Role of pubofemoral ligament
Limit extension and adduction of hip
Role of ischiofemoral ligament
Stabilise hip + limit hip extension and medial rotation
Role of labrum
Fibrocartilaginous collar surrounding acetabulum, Increases stability by increasing articulation area with head of femur
Muscles of anterior hip and nerve supply + vascular supply
Iliopsoas (iliacus + psoas major)
Femoral nerve and artery
Iliacus origin, insertion and action
O = iliac fossa
I = lesser trochanter of femur
A = hip flexion
Psoas major origin, insertion and action
O = t12-L4 bodies and costal processes of L1-5
I = lesser trochanter of femur
A = hip flexion
Muscles of posterior hip and nerve and vascular supply
(Superficial) = Gluteus medius, Gluteus maximus, Tensor Fascia Latae
Deep = superior gemellus,piriformis, inferior gemellus, obturator interns, Quadratus femoris
Superior gemellus O,I,A
O = ischial spine
I= Greater trochanter
A = lateral hip rotation
Piriformis O,I,A
O = Pelvis surface of sacrum
I = greater trochanter of femur
A = lateral rotation of hip
Inferior gemellus O,I,A
O = Ischial tuberosity
I = greater trochanter of femur
A = lateral rotation of hip
Obturator internus O,I,A
O = obturator membrane
I = greater trochanter of femur A
A = lateral rotation of hip
Glute medius O,I,A
O = gluteal surface of ileum
I = greater trochanter of femur
A = abduction of hip
