Abstract:
A disc prosthesis for insertion between vertebrae of the spin has upper and lower members and a pivot ball retained in a socket to prevent the ball from becoming removed from the socket. Also, a shock absorbing member is fitted between the upper and lower member of the prosthesis. The upper and lower members are also vertically movable to compress the shock absorbing member and absorb shock in the spine.
