and methods for attaching an implant to bone are disclosed. In one embodiment, the device 10 includes an elongated stud 15 defining an engaging surface 16 and a foot 20 projecting outwardly from an end 18 of the stud 15. The foot 20 is receivable through an opening O in the cortical layer R of the bone B and includes an upper surface 21 for contacting an internal surface R' of the cortical layer R. A fastener 25 is provided for engaging the engaging surface 16 of the stud 15, having a surface 29 for bearing against the implant I to clamp the implant I to the bone B when the fastener 25 is engaged to the engaging surface 16 of the stud 15 and the foot 20 is received in the opening O. In another embodiment, the apparatus 30 includes a number of additional studs 31 which are extendable together through the opening O. A wedge 36 can be provided to clamp the multiple studs within the bone opening.

The construction and manufacturing technique for a functional biocompatible intervertebral disc spacer is described. This device is useful for a replacement for a degenerated disc in certain treatments of back pain and spinal disease. The disc spacer possesses mechanical properties akin to those of the normal disc and will preserve normal functions of the spinal motion segment. The device achieves the desired properties by varying the hardness of the elastomeric material in its nucleus and annulus.
