What is the hip joint?
Synovial, polyaixal ball and socket joint
flexion and extension
abduction and adduction
medial and lateral rotation
Describe the acetabulum
Lunate surface of hyaline cartilage horseshoe shaped
thickest above and centrally for weight bearing
non articular region of actebular fossa and notch is covered with fat
Describe the head of the femur
spheroid in shape
covered in hyaline cartilage
thicker centrally than in the periphery
cartilage is deficiënt over the fossa
Limitation to range of motion
tension of antagonists
soft tissue apposition
tension of ligaments limit range
What is the sacro iliac joint?
synovial plane joint
nutation and counter nutation
What is the iliofemoral ligament
apex- AIIS
base- intertrochanteric line
limits extension and abduction
What is the pubofemoral ligament
from he pubic eminence to the capsule and the medial band of the iliofemoral ligament
limits extension and abduction
What is the ischiofemoral ligament?
from the inferior aspect of the ilium to the capsule and anterior part of the greater trochanter
limits extension and medial rotation
ligament teres
from a pit in the head of the femur
to the acetabular notch and transverse acetabular ligament
