FIELD: medicine, traumatology, vertebrology. SUBSTANCE: proposed endoprosthesis is manufactured of material exhibiting thermomechanical shape memory effect over temperature range from +30 to +45 C, and constituted by single-turn spiral whose sharpened ends are directed in opposite directions along straight line parallel to spiral turn axis. Endoprosthesis can be used in surgical operations on spine involving removal of intervertebral disc. EFFECT: reliable fixation of vertebrae, lower traumatism, shorter operation duration, complete immobilization of vertebrae and device itself during operation, ruled-out possibility of compressing spinal cord, simpler manufacture and operation of proposed intervertebral disc endoprosthesis. 4 dwg
