Abstract
The vertebrae implant has a stabilizing element which is articulated to a pair of bone screws so as to accommodate skew positions of the bone screws relative to each other. A slotted clamp is provided to secure the stabilizing element to each bone screw. In addition, each clamp is disposed between a shoulder having a spherical surface and a clamping nut. A washer is also disposed between the clamping nut and the clamp. The clamping nut and/or washer is provided with a spherical surface to provide for pivoting of the clamp relative to the bone screw prior to tightening of the clamping nut.
