ABSTRACT:
A system for assembling two components of a prosthesis in a plurality of positions which are adjustable in orthogonal translation, and selectively in rotation and angularly. In the system, a projecting part integral with one of these components is engaged in a recess, forming a hollow part of the other component of the prosthesis, or of an intermediate connection element, while screws arranged transversely with respect to the lateral walls of the cell come into abutment, as in the prior art, against the lateral flanks of the projecting part, but without the base of the hollow part bearing directly against the facing surface of the projecting part. Outer edges of the recess forming the hollow part bear in such a way against sets of screw so as to be able to slide in a rectilinear manner in at least one direction relative to the extent of a surface of the component with which the projecting part is integral, this projecting part being spaced in any position thereof from the base of the recess forming the hollow part.
