METHOD FOR PREPARING NON-TOXIC POROUS IMPLANT OF POLYLACTIC ACID FOR BUILDING OF LONG BONE DEFECTS

摘要

FIELD: medicine.;SUBSTANCE: invention refers to medicine, particularly traumatology and orthopedics, and can find application in treating false joints of long bones. What is described is a method for preparing a non-toxic porous implant of polylactic acid with controlled pore size for building of long bone defects involving melting the polylactic acid granules in a melting pot immersed in thermally stable oil with porogen presented by sodium chloride crystals 100-250 nm to be washed out by aqueous solutions of antiseptics. The implant is prepared with no toxic solvents added and has a pre-set pore diameter.;EFFECT: improved efficiency of the method.
