FIELD: medicine.SUBSTANCE: method involves using calcium-phosphate coated (CPC) implants with the coating formed of calcium phosphate globules 0.8-150 mcm in diameter and consisting of spherolith-like crystals forming a coating surface macrorelief with a pore size falling within the range of 5-100 mcm. The used CPC is characterised by porosity 50-60%, thickness 10-40 mcm. The CPC composition contains, vol %: hydroxyapatite - 66-72, titanium - 1.3-1.8, titanium dioxide - 2.0-2.4, the rest - an amorphous phase. The amorphous phase of the CPC consists of at least one compound specified in a group including calcium dihydrophosphates, calcium hydroxyphosphates, calcium titanate, calcium titanium diphosphate.EFFECT: method provides stable tension fixation of bone fragments, and durable fixation of an implant and bone, adequate blood supply and functional load, high ability of implant integration with minimising a negative body reaction to a foreign matter.3 dwg, 2 tbl |
