Embodiment

[0094] The bone graft of bioactive glass is prepared according to the former Chinese patent technology (a degradable porous bioactive glass scaffold and its preparation method, patent publication number: CN1562834, 2005.1.12). However, according to the specific requirements of this clinical application, it is necessary to have a certain compressive strength to support the filling in this defect without breaking and collapsing after filling; in addition, the compressive strength should not be too high, as it will make the material Too hard to fuse with the body bone tissue.

[0095] Changes in the strength of bioactive glass-based bone grafts in biological environments or human tissue are also key to successful clinical use. If the strength decreases rapidly in the biological environment or human tissue, it will cause the bone graft to break and collapse and cannot play a supporting role in the filled defect. Experiment 1 is to use Simulated Body Fluid (SBF), which is commonly...

Abstract

The application relates to a bone grafting body and a bone grafting body of bioactive glass, a preparation method thereof, and a purpose of the bioactive glass for preparing the bone grafting body. The bone grafting body comprises a bone block for inserting into a hip joint to replace an autologous iliac bone and a fixing member for fixing the bone block to the hip joint. The bone grafting body is advantageous in that the structure is simple, the connection with the joint is firm after surgery, the stability of the area of bone grafting can be improved, and the joint shaping is good.

Description

technical field [0001] The present application relates to a bone graft body and a bioactive glass bone graft body, a preparation method thereof, and the use of the bioactive glass for preparing the bone graft body. Background technique [0002] Developmental Dislocation of the Hip (DDH) is one of the most common bone and joint deformities of the lower extremities in children. Long-term biomechanical abnormalities due to poor coverage of the acetabulum on the femoral head due to defective acetabular development. Early treatment is the basic principle for dealing with DDH at present. For children who are found late and whose age exceeds the range of conservative treatment, surgery is a routine treatment method, which can restore the normal correspondence between the femoral head and the acetabulum, and is conducive to the normal development of the hip joint. Conventional surgical methods require acetabular osteotomy, and the gap after osteotomy needs to be filled with bone gr...
