Title:
FEMORAL STEM DESIGN METHOD
Document Type and Number:
WIPO Patent Application WO/2022/145814
Kind Code:
A1
Abstract:
The present invention relates to a femoral stem design method and, more specifically, to a femoral stem design method comprising: a data collection step of collecting femur data from a plurality of patients; a measurement standard setting step of setting a standard for designing a femoral stem with respect to the femur data of the plurality of patients collected in the data collection step; a measurement step of measuring a predetermined part of a femur from the plurality of femur data; a dimension determination step of determining dimensions of each part of a plurality of implants to be inserted into the femur; and a shape determination step of determining shapes of the plurality of implants according to the dimensions of the plurality of implants determined in the dimension determination step, wherein the measurement standard setting step includes a boundary setting step of setting a boundary that distinguishes cortical bone and cancellous bone from the femur data of the plurality of patients, and an axis setting step of setting an axis extending from the proximal part to the distal part of the femur. Accordingly, during the design of an artificial femoral stem to be inserted into a femur in surgical procedures such as hip arthroplasty, data analysis is quickly carried out by using minimal anatomical data through a patient's 2D-based human anatomical information, and implants are designed to have regular shapes corresponding to the anatomical shape of a patient's femur.
