Review Of Lower Extremity Packet - Hip

Front 1

hip joint

Back 1

articulation between the head of femur and acetabulum
synovial ball and socket joint

Front 2

acetabulum

Back 2

horseshoe shaped witeh acetabular notch at inferiority

Front 3

acetabular labrium

Back 3

a fibrocartilaginous rim that deepens the acetabulum
-bridges the acetabular notch at the transverse acetabular ligament

Front 4

hip capsule

Back 4

encloses the joint and is attached medially to the acetabular labrium.
attached laterally to the intertrochanteric line of the -femur anteriorally and halfway along the posterior aspect of the neck of the femur
-reinforced by the iliofemoral, pubofemoral and ischiofemoral ligaments

Front 5

iliofemoral ligament

Back 5

strongest/most imp ligament of hip joint
-shaped by inverted Y
-base is att. to anterioinferior iliac spine above
-two limbs of Y are att. to the upper and lower parts of the intertrochanteric line of the femur
-ligament resists hyperextension and lateral rotation of the hip joint

Front 6

pubofemoral ligament

Back 6

triangular shape
-base is att. superiorly to the superior ramus of the pubis
-apex is att below the lower end of the intertrochanteric line
-limits abduction and lateral rotation of the hip

Front 7

ishiofemoral ligament

Back 7

spiral in shape
-att. to body of the ischium and laterally to the greater trochanter of the femur
-limits medial rotation of the hip joint

Front 8

ligament of the head of femur

Back 8

flat and triangular shape
-att by the apex to the fovea capitis of the femur
-by its base to the transverse acetabular ligament
-by the margins to the acetabular notch
-limits adduction of the hip joint

Front 9

synovial membrane of hip joint

Back 9

lines capsule
covers portion of femoral neck that lies within the joint capsule
ensheathes the ligament of the head and the femur and covers the floow of the acetabular fossa
communicates w/ psoas bursa
