Effect of Hydroxyapatite Composite Nano-Artificial Bone on Treatment and Rehabilitation of Patients with Ankle Joint Injury.

The formation of natural bone tissue is the result of the joint regulation of multiple template molecules. Although its complex hierarchical structure has been studied for many years, the mechanism of biomineralization of hard bone tissue has not been fully clarified. In this paper, the nanocomposites obtained by mineralization were characterized and analyzed, and the effect of the template on the crystal formation of hydroxyapatite was studied. The characterization results show that the main phase of the inorganic mineral obtained by template mineralization is the hydroxyapatite phase. The nano-apatite composite particles with an inorganic component content of 90.2% have the highest loading efficiency, reaching 67.9 mg/g. By statistical analysis of the pain scores at 5 days, 10 days, and 15 days after ankle injury, it was found that the average pain score of the treatment group was smaller than that of the control group. Two weeks later, the clinical efficacy judgment standard statistics show that the treatment group has a 22.5% improvement in healing rate, a significant increase in 3.18%, and a total effective rate of 8.71%, which is significantly better than the control group.
