REGULATED SPINAL PROSTHESIS Russian patent published in 2010 - IPC A61B17/70 

FIELD: medicine.

SUBSTANCE: spinal prosthesis contains first element of spinal prosthesis fastened to first spinal structure, and second element of spinal prosthesis, fastened to second spinal structure. First and second elements of spinal prosthesis are movably joined with each other by means of fastening device which has untight position, allowing spatial movement of first and second elements of spinal prosthesis relative to each other with obtaining desired orientation, and tight position, in which first and second elements of spinal prosthesis are fixed with relation to each other in desired orientation. First element of spinal prosthesis contains monolithic body which includes flexible knot located between first and second connecting elements. Hogging of flexible knot allows to move first connecting element relative to second connecting element. First connecting element has at least one connecting point for connection with first spinal structure. Second connecting element is movably connected with second element of spinal prosthesis by means of said fastening device.

EFFECT: invention has possibility of on-site regulation, for instance lordosis angle in prosthesis.
