Abstract
A prosthesis includes: two pairs of elongated joint elements forming disc joint surfaces and facet joint surfaces; one pair of elements able to be positioned relative to each other. Each disc joint surface is in the shape of a hemisphere portion; positioning surfaces including posterior positioning surfaces; the prosthesis is associated with at least one rigid transverse element comprising positioning surfaces designed to be placed against the posterior positioning surfaces. Such placement permits one pair of joint elements to be positioned relative to the other pair of joint elements such that the disc joint surfaces are situated in a same geometric hemisphere.
