what does coxa vara cause
knee valga
what are the 2 conditions if you have an abnormal angle of inclination
coxa valga
coxa vara
explain coxa vara
Line through fovea and interscretion with line of the shaft of the humerus
If that angle is decreased (less than 120), femur will shift inward and cause a knee valga (knee goes in to compensate)
causes knock knees

true or false: vara means decreased angle/caving in
true
explain coxa valga
if angle is increased, femur will move outward
causing knee vara
bowlegged
explain the 2 cases of femoral anterversion
looking from a superior view, the angle through the hum and down the femur
1) if this angle is small, shaft has a medial roation causing toes to move inward (HED OF THE FEMUR STILL CENTRALZIEDO
2) if the angle is small AND THE HEAD OF THE FEMUR IS SITTING ANTERIORLY , toes will appear straight howver there will be uneven wear of the labrum
explain 2 cases of femoral retroversion
looking at angle superiorly
1) Angle is too big, shaft will have a lateral rotation causing toes to toe out
BUT HEAD IS STILL CENTRALIZED IN FOSSA
2) angle is still big but the HEAD IS POSISTIONED POSTERIORLY, no toe out will occur but there will be a posterior wear of the labrium
