AI Technical Summary

Problems solved by technology

In such femoral fractures, bone screws are sometimes required to fix the bone plate on the proximal femoral bone. However, because the replaced femoral condyle has an intercondylar box, it is difficult for the bone screw to penetrate the proximal femur to fix the bone plate.

Abstract

The invention provides a femoral condyle prosthesis and a knee joint prosthesis. The femoral condyle prosthesis comprises a femoral condyle body, a semi-open intercondylar box is arranged on the femoral condyle body, a groove is arranged on the intercondylar box, and a groove is arranged on the femoral condyle body. The body is provided with planes on both sides of the intercondylar box, and positioning columns are provided on the planes. Knee prostheses include femoral condyle prostheses. The femoral condyle prosthesis and knee joint prosthesis have a semi-open intercondylar box, which can improve microbial sealing, have better connection strength, strong stability, and patients are not prone to fractures. The groove of the intercondylar box is designed to reserve the position of the bone nail. After the bone nail passes through the bottom of the groove, the bone nail penetrates into the proximal femur to fix the bone plate.

Description

technical field [0001] The invention relates to the technical field of orthopedic medicine, in particular to a femoral condyle prosthesis and a knee joint prosthesis. Background technique [0002] In recent years, artificial femoral condyle replacement has developed rapidly and matured, and more and more patients choose artificial femoral condyle replacement. The existing artificial femoral condyle prosthesis has the following problems. Patients will experience various unexpected situations after surgery, especially cases of femoral fractures caused by limited mobility and osteoporosis occur from time to time. In this femoral fracture situation, bone nails are sometimes required to fix the bone plate on the proximal femur bone, but because the replaced existing femoral condyle has an intercondylar box, it is difficult for the bone nails to penetrate into the proximal femur to fix the bone plate. Contents of the invention [0003] The present invention provides a femoral c...
