- Discussion:
- abductor weakness:
- to improve abductor function when a femoral component is revised for
excessive leg lengthening;
- acetabular exposure:
- difficult acetabular reconstructions may require wide exposure afforded
by trochanteric osteotomy (
DDH, prior acetabular frx, and revisions
w/ substantial loss of bone stock);
- severe
protrusion
- on only will trochanteric osteotomy provide better exposure, but it
will also allow for proper soft tissue tension as the leg is restored
back to its proper length;
- conversion of arthrodesis to a total hip arthroplasty;
- removal of femoral component:
- if the femoral component has been placed in varus or if there is a
large overhanging trochanteric shoulder, then ostetomy is required;;
- sibsidence of femoral component;
- when leg length will be increased significantly (as in the case of
protrusio or femoral subsidence);
