FIELD: medical engineering.
SUBSTANCE: device has neck and collar members and a rod. Self-jamming inserts manufactured from mesoporous plates of osteocompatible biosital material shaped as pyramid having trapezium-shaped cross-section are fixed on lateral sides of proximal rod part in parallel to endoprosthesis pedicle collar member in slots not more than 2 cm far from the collar member.
EFFECT: high strength and reliability in fixing prosthesis pedicle.
