ORIENTATION OF THE FEMORAL COMPONENT IN SURFACE ARTHROPLASTY OF THE HIP

Abstract

Optimizing the femoral stem-shaft angle toward a valgus orientation during the preparation of the femoral head is important when a hip is being reconstructed with a surface arthroplasty because the resurfaced hip transmits the load through a narrow critical zone in the femoral head-neck region and the valgus angulation may reduce these stresses.
