Abstract

The functioning and survival of hip resurfacing arthroplasty depends on correct positioning and alignment of the implant. Correct positioning of the femoral alignment wire with respect to the femoral neck is the key to avoiding complications. Although the surgeon must align the wire in two planes, we can only control one plane at a time without changing position or relying on the indications of an assistant. Independent placement of two parallel alignment wires, one for varus-valgus orientation and another for version orientation, will help to determine two planes, the valgus sagittal plane and the version coronal plane, at the intersection of which both the optimum point of entry into the femoral head and the orientation line of the femoral alignment wire can be established. The marks on the neck and head and Kirschner wires following these marks define the planes. This simple technique allows us to reduce surgery time, minimize errors, and speed up the learning curve. It can be used with any type of resurfacing arthroplasty.
