Cephalad and caudal vertebral facet joint prostheses and methods of use
are provided. The cephalad prostheses are adapted and configured to be
attached to a lamina portion of a vertebra without blocking a pedicle
portion of the cephalad vertebra. In some embodiments, the prosthesis is
attached with a non-invasive support member, such as a clamp. In other
embodiments, a translaminar screw may be used for additional fixation.
