Valgus Deformity

What is it?

Valgus deformity of the femur is where the neck – shaft angle is increased, and where the femoral neck is unduly straight.

It is most commonly discovered in patients who have hip dislocation or hip dysplasia, and is frequently accompanied by increased femoral neck anteversion (see Rotational Deformities).

Valgus deformity of the femur is not always symptomatic and if it co-exists with a shallow hip socket or acetabular dysplasia, the operation likely to give the best outcome is treatment of the socket and not of the femur.

If the valgus deformity is severe it may be necessary to perform a Varus Osteotomy.
