Hip resurfacing is a popular procedure among patients and surgeons. The principal concepts of hip resurfacing are simple, yet demanding, as the procedure has limited tolerance to placement errors, especially for the femoral component. In current technical manuals, the placement of a guide wire seated in the neck is crucial. This guide wire is usually applied by the use of jigs that are intended to align to the neck axis. After evaluating the position of the guide wire, it is necessary to reposition it in many cases. We propose the use of a specially designed readjustment jig that takes advantage of the first guide wire, and gives defined offset and angulations for the placement of a second guide wire. A simple set of disks with different offsets and angulations in relation to a central hole has been developed to serve as a tool to readjust the positioning of the central guide wire in hip resurfacing.
