Abstract
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.
Claims20
A method of preparing a proximal femur of a patient for implantation of a femoral implant as part of a total hip arthroplasty procedure, the method comprising:
- a) preoperatively planning the total hip arthroplasty procedure on the proximal femur of the patient, the preoperative planning including:
- i) causing a first center and a second center to positionally correspond in a computer coordinate system, wherein the first center is a center of a femoral head of a three dimensional computer model of the proximal femur and the second center is a center of a femoral head of a three dimensional computer model of the femoral implant;
- and
- ii) computer defining a resection of the proximal femur in the computer coordinate system when the first and second centers positionally correspond in the computer coordinate system;
- and
- b) resecting the proximal femur of the patient according to the computer defined resection.
