| titleOfInvention | Hip fixation screw |
| abstract | PROBLEM TO BE SOLVED: To provide a strength and rigidity (elasticity) close to that of a living bone, and to maintain and maintain the high strength until the outer cup of the artificial hip joint is fixed to the femur. After that, it is rapidly hydrolyzed, the decomposed particles and the inorganic filler are absorbed into the living body without dispersing around, and the inner cup is not damaged by large bulk decomposed debris. An ideal screw for artificial hip joint fixation, in which the screw is not loosened due to bonding with the surrounding bone in 2 weeks, the bone is conductively formed in the screw hole as the hydrolysis proceeds, and the screw hole is filled while replacing the screw. I will provide a. SOLUTION: This is a screw 10 made of a biodegradable and absorbable polymer for fixing an outer cup of an artificial hip joint, wherein the polymer has a viscosity average molecular weight of 150,000 to 400,000, a compression bending elastic modulus of 7 GPa to 15 GPa, and a compression bending strength. Is 150 MPa or more, and the bioactive inorganic filler is 2 0 to 50% by weight and exposed on the screw surface. |
