摘要：
Group The invention relates to the field of medicine, in particular, to medical devices used in traumatology and orthopedics. The tibial component is made from bone cement with antimicrobial chemotherapies and is flattened longitudinally elongated rounded base with front, rear and side surfaces of the cavity in the central part of the rear side surface. On the outer surface of the base of the tibial component recesses in the form of two elongated parallel grooves arranged transverse to the longitudinal axis of the base ensuring their sliding contact with the articular surface of the femoral component of the spacer. From the side of the back surface of the base of the tibial component in its central part there is a fastening element of the intramedullary stem type as a projection shape of a truncated cone. On the back surface of the tibial base component formed by at least two elongated protrusion disposed on both sides of the intramedullary attachment element and on one side oriented from the base center to the periphery towards its front and rear side surfaces indented 3-5 mm from them at an angle of 30-45 ° to the longitudinal axis of the base, on the other hand, smoothly passing into the indentations on the type of ribs disposed on the outer surface of the intramedullary attachment element. Mold for manufacturing the intraoperative tibial component articulating knee spacer is made of silicone and is a split housing comprised of longitudinally flattened elongated laths and a base in the form of a rectangular parallelepiped with a back, a front end longitudinally extended and lateral, top, bottom walls. The top parallelepipedic zone formed two-stage depression forming a cavity of complex shape, consisting of a lower chamber frustoconical shape facing the small base to the bottom wall of the housing base, and a longitudinally elongated upper chamber rounded with kidney-shaped longitudinal section facing the rear longitudinally elongated side wall of the base .
