New polymer nano-biomaterials in rehabilitation nursing of orthopedic surgery injuries

Abstract

Changes in nano-bio materials’ surface electronic structure and crystal structure produce small-size effects that macroscopic objects do not have. This makes it have a series of excellent macroscopic properties such as force, magnetism, electricity, optics, chemistry, and biology that traditional materials do not have. This article studies the application of new polymer nano-bio materials in orthopedic trauma. We study the effect of nanolevel hydroxyapatite gradient coating on the expression of osteoblast phenotypic factors. The shear strength of the implant-bone interface is better than the titanium alloy group and the titanium alloy group. So we can conclude that the nano-grade hydroxyapatite gradient coating material has good biological characteristics. It can promote the early healing of the bone trauma interface. This material is worthy of clinical application.
