Abstract

An implant for use in spinal stabilization includes four generally linear thread segments. The thread segments are maintained and spaced apart alignment by rigid supports. The thread segments include a plurality of individual threads with the individual threads of the segments defining a thread pattern. The supports and the thread segments define a hollow implant interior exposed to an exterior of the implant.
