Abstract

A spinal interbody distractor is provided that is configured to provide distraction of adjacent vertebrae after implantation within a spinal disc cavity through manual rotation of the distractor once implanted. Such implantation is preferably, but not necessarily, through minimally invasive surgical techniques. In one form, the distractor is configured to be rotated 90° to 180° after implantation to provide distraction of adjacent vertebrae. The distractor has a lateral side to lateral side height of a first length and a superior end to inferior end height of a second length that is greater than the first length. This configuration allows the distractor to be inserted into a spinal disc cavity having an opening with a height that is smaller than an end height of the spinal disc cavity after implantation thereof, thereby providing distraction of adjacent vertebrae. The spinal interbody distractor may have one or more cavities, areas, openings and/or bores for spinal fusion material when the distractor is used as a fusion body. The spinal interbody distractor is made from a biocompatible material such as a thermoplastic (e.g. PEEK), a polymer, metal, combination thereof or otherwise, such as desired and/or is appropriate.
