Module for filling and supporting femoral head necrosis area and manufacturing and using method thereof

Abstract

The invention provides a module for filling and supporting a femoral head necrosis area and a manufacturing method thereof. The module comprises a module body, the module body is a metal product whichis the same as or similar to a femoral head necrosis area of a patient in shape, bone ingrowth can be generated on the surface of the module body, the module body is of a hollow structure and is filled with a bone grafting material, the bone grafting material is autologous or allogenic or an artificial bone grafting material, and holes are formed in the surface of the module body, so that the module body can be in a sieve mesh shape or a honeycomb shape. The invention solves the problems that an existing femoral head necrosis early-stage and middle-stage supporting method is unreasonable, anexisting supporting structure has an inherent structure and is not matched with a femoral head necrosis area in form, consequently, the supporting local area is insufficient, the strength is inconsistent, part of the necrosis area cannot be effectively supported, and the treatment effect is affected. The invention belongs to the technical field of femoral head repair.

Description

technical field [0001] The invention provides a module for filling and supporting a femoral head necrosis area and a method for making and using the same, belonging to the field of femoral head repair. Background technique [0002] In the early and middle stages of femoral head necrosis, including traumatic and non-traumatic, the main manifestations are crescent-shaped and semi-circular cystic changes due to local blood circulation disturbance and necrosis, which reduce local strength, lack of support for the human body, and gradually Microfractures and local collapses occur, making the spherical femoral head uneven and not smooth, losing its matching with the acetabulum, and finally causing the wear and tear of articular cartilage. During this series of changes, the patient will experience pain and dysfunction . The purpose of early and mid-term surgical treatment is mainly to keep the femoral head from collapse and deformation; common methods include: 1) decompression of ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a module for filling and supporting the femoral head necrosis area and its production and use method, so as to solve the unreasonable support method in the early and middle stages of the existing femoral head necrosis, and the existing support structures all have inherent structures The shape does not match or match the shape of the femoral head necrosis area, resulting in insufficient local area of ​​support and inconsistent strength. Part of the necrosis area cannot be effectively supported, which affects the treatment effect.
