Question 1

What are the effects that Coxa Valga has on the Hip?

Answer 1

• Alters the orientation of joint reaction forces
• Hip Abductors are shortened, putting them at a disadvantage and causes them to contract more vigoroously to stabilize the pelvis, increaseing JRF
• Increases overall length of the LE, impacting the kinetic chain

Question 2

What are the effects that Coxa Vara has on the Hip?

Answer 2

• Increases downward shear forces on femoral head
• JRF are decreased as the greater trochanter is displaced laterally and superiorly, increasing the pull angle and the hip abductor lever arm
• There may be an increase of incidence of epiphyseal plate damage with the increased shearing and torsional forces
