FIELD: medicine.SUBSTANCE: ablation of nucleus pulposus and sequestrectomy are carried out; implant is introduced into enucleated disc. As implant applied is nitinol thread, folded in form of spherical ball, diameter of which is 4-6 mm larger than height of disc cavity. Preliminarily cooled implant is pressed, and after its placement into disc, work spherical shape is given by heating to 40-45°C.EFFECT: method makes it possible to reduce complications, which is reached due to elasticity of nitinol, providing protection of over- and underlying vertebrae from increased load from implant, with nitinol shape-memory effect ensuring support of given shape of intervertebral disc.1 ex |
