A spinal implant configured to connect to a vertebra. The spinal implant comprises a ball and socket joint allowing poly-axial movement. The ball and socket joint includes a socket having a multiple radius tear drop geometry with a larger radius and a smaller radius, so that the ball can move freely within the larger radius of the socket until it is seated into the smaller radius of the socket upon locking of the ball and socket joint.

A spinal fusion clamp implant that connects two vertebra, preferably the C1 and C2 vertebra. The clamp implant includes a clamp assembly that connects to the C1 vertebra. The clamp assembly includes at least one superior jaw and at least one inferior jaw. The superior jaw and the inferior jaw are opposedly arranged and clamp onto posterior arch of the C1 vertebra. The clamp implant also includes an implant assembly that connects to the implant used in C2, and a connection system that connects the clamp assembly with said C2 implant assembly.
