Pelvic Girdle is?
ring-like bony structure, located in the lower part of the trunk and connects the axial skeleton to the
lower limbs.
what is the innominate made up of?
Ilium, Pubis, Ischium
What does the Labrum do?
increases the depth of acetabulum and enhances stability by acting as a seal
what percent is the ischium of acetabulum
40%
what percent is the illium of acetabulum
40%
what percent is the pubis of acetabulum
20%
what direction does the acetabulum face
laterally and inferiorly facing
what is the acetabular fossa
the non articular floor of hip
, what shape is the lunate/articular area and how is it connected
horseshoe shaped and connects inferiorly by transverse acetabular ligament
how is acetabular depth measured
measured by using center edge angle of wiberg (25 degrees)
Center edge angle is?
angle formed by a line drawn from the center of the femoral head to the outer edge of the
acetabular roof, and a verticle line drawn through the center of the femoral head
Acetabular dysplasia is?
abnormally shallow acetabulum
coxa profunda/acetabular protrusion is?
acetabulum excessively covers femoral head
Normal Angle of Inclination?
125 degrees normal
what is the normal alignment of hip at birth? greater than 125 degrees (usually 140)
Coxa Valga is what at birth?
Positives of Coxa Vara
increased moment arm for hip abductor force
alignment may improve joint stability
Negatives for Coxa Vara
increased bending moment arm increases bending moment.
increases shear force across femoral neck
Positives of Coxa Valga
decreased bending moment arm
decreases bending moment
decreases shear force across femoral neck
