Total hip replacement surgical guide tool

摘要

Disclosed herein is a surgical guide tool for use in total hip replacement surgery. The surgical guide tool may include a customized mating region and a resection guide. The customized mating region and the resection guide are referenced to each other such that, when the customized mating region matingly engages a surface area of a proximal femur, the resection guide will be aligned to guide a resectioning of the proximal femur along a preoperatively planned resection plane.

1. A surgical guide tool for use in the preparation of a proximal portion of a femur for the implantation of a total hip replacement prosthetic implant, the implant including a feature configured to abut against a resection surface of the proximal femur when the implant is fully implanted in the proximal femur in a manner that generally replicates a preoperatively planned implantation for the implant, the tool comprising: a mating region including a customized surface contour that is generally a negative of the proximal portion of the femur, the surface contour of the mating region being configured to matingly contact the proximal portion in a generally matching or interdigitating manner when the proximal portion is matingly received by the mating region and a saw guide, wherein, when the mating region matingly contacts the proximal portion, the saw guide is aligned with a resection plane generally corresponding to the resection surface.
