METHOD FOR OBTAINING LOW-TEMPERATURE BIORESORBABLE COMPOSITE MATERIAL BASED ON HYDROXYAPATITE, REINFORCED WITH MAGNESIUM PARTICLES USING ELECTRO-PULSE COMPACTION METHOD FOR USE AS IMPLANT IN OSTEOSYNTHESIS Russian patent published in 2021 - IPC A61L27/42 A61L27/56 A61K6/838 A61K6/84 A61F2/28 A61P19/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to traumatology and orthopedics, and discloses a method for producing a bioresorbable composite material based on hydroxyapatite, reinforced with magnesium particles. The method is characterized in that it includes mixing and grinding of the starting powder materials, which are magnesium and hydroxyapatite, in an inert gas atmosphere in a planetary mill, followed by compaction of the mixture by the electric pulse method, while the content of the hydroxyapatite phase in the powder mixture is 70-90 wt.%, and the content of the magnesium phase is 10-30 wt.%.

EFFECT: obtained composite material based on hydroxyapatite reinforced with magnesium particles is characterized by a compressive strength of at least 250 MPa and an open porosity of at least 10% and can be used as a bioresorbable implant material in osteosynthesis after various injuries.
