Modeling method of necrotic femoral head repair model based on umbrella-shaped femoral head support

Abstract

The invention discloses a modeling method of a necrotic femoral head repair model based on an umbrella-shaped femoral head supporter. The bone is the femoral head that has femoral tissue necrosis area and is pre-repaired with the femoral head supporter; Necrotic femoral head model; 3. Establishment of femoral head support model; 4. Establishment of necrotic femoral head implant model: establishment of necrotic femoral head implant model with implant channel and 3D model of implanted bone; 5. Necrotic femoral head repair Model building. The method of the invention has simple steps, reasonable design, convenient implementation and good use effect, and can easily and rapidly establish a repair model for implanting a femoral head supporter into a necrotic femoral head, and the established repair model is of high quality.

Description

technical field

[0001] The invention relates to a modeling method, in particular to a modeling method of a necrotic femoral head repair model based on an umbrella-shaped femoral head supporter. Background technique

[0002] There are many studies abroad on the treatment of avascular necrosis of the femoral head. Castro et al. from the Department of Plastic Surgery, Tulane University School of Medicine analyzed the efficacy of core decompression in the treatment of avascular necrosis of the femoral head through Meta-analysis, and conducted a statistical study on the efficacy of single core decompression surgery. The analysis showed that the success rate of core decompression was statistically better than that of conservative treatment, but it was still not the best treatment method. Meta-analysis is a kind of statistical method that synthesizes the results of many researches on the same subject with specific conditions. This analysis method is often used in statistical resea...
