Abstract
A device (3) used to fit a nucleus prosthesis made up of: a deformable elastic nucleus prosthesis (1) which can adapt to the shape of intervertebral cavities, the prosthesis consisting of two parts, namely a male part (11) and a female part (12); and an insertion assembly (2) which is connected to the nucleus prosthesis (1). The elastic deformation of the nucleus prosthesis (1) makes it possible for the prosthesis to be inserted into the intervertebral cavity. The prosthesis is inserted using the elasticity thereof and the insertion means (2) which form part of the device (3) before insertion, but which can be subsequently removed.
