FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to traumatology and orthopedics, to method of treating osteochondral injuries of talus block by method of mosaic autochondroplasty of affected sections with their further replacement with autotransplants. Blind holes are drilled in bone block, layer of granules of complex alloplastic apparatus, containing 50-60 wt % of collagen, is laid on their bottom. After that, cylindrical osteochondral autotransplants are pressed in with cartilage out. Joint is filled with gel-like platelet-enriched autoplasma. Medial ankle is repositioned and fixed. The remaining autoplasma is returned into patient's blood stream. Granules can additionally contain 0.08-2.8 wt % of colloid solution of zerovalent metal silver nanoparticles. Size of used colloid zerovalent silver nanoparticles is selected from 2 nm to 25 nm. Quantity of blind holes is selected depending on degree of block affection. Diameter of autotransplants and diameter of holes is selected from 4 to 8 mm. Length of autotransplants and depth of holes is selected from 8 to 25 mm. Thickness of layer of granules laid on the bottom of holes is from 0.2 to 1.0 mm.
EFFECT: method ensures movement and support of ankle joint.
