the approach used reduces the torque-to-failure (fracture) of the construct to less than 50% of the intact femur.

the technique of repair can return the reconstructed prosthesis/bone composite to nearly the strength of the intact femur.

there is no relationship between the density of the native bone and the strength of the prosthesis/bone composite.

the addition of bone graft substitute or autograft has been shown to lessen the time to complete healing.

there is a one in five chance of fracture with this technique; therefore, the surgeon must carefully weigh the potential benefits versus this risk.

The transfemoral approach, also known as the extended trochanteric osteotomy, is an important technique to master for revision hip surgery. When performed correctly, it allows excellent exposure of the femoral canal and aids in exposure of the acetabulum. As demonstrated in the study cited, however, it markedly reduces the torque that the composite can withstand without failure. This type of basic science study is important to guide postoperative rehabilitation.
