<p>An intervertebral disc prosthesis (50) that comprises a deformable flexure (100) with an axial cavity (105), the axial cavity (105) extending along the axis of the flexure (100); a slit (101) defined in the perimeter surface of the flexure (100) to provide flexibility to the disc member, the slit (101) having a slit thickness. The slit (101) may be in the form of a coil to impart a spring-like appearance and function. The intervertebral disc prosthesis (50) further comprises a lower disc support (102) housed in the axial cavity and an upper disc support (104) housed in the axial cavity; with the lower and upper disk supports (102, 104) communicating with one another to provide support to the disc. The lower or upper disc support (102, 104) may alternatively be incorporated into the flexure.</p> |
