SPINAL FACET CAGE IMPLANT

摘要

Implementations described and claimed herein provide a spinal facet cage implant for implantation in a spinal facet joint. In one implementation, the implant includes a distal leading end, a proximal trailing end, a first face, and a second face. The distal leading end has a distal surface generally opposite a proximal surface of the proximal trailing end. The first face has a first surface that is generally parallel with a second surface of the second face. The first and second faces extend between the distal leading end and the proximal trailing end. The first and second surfaces having one or more textured features adapted to provide friction with the spinal facet joint. One or more windows are defined in the first and/or second surfaces, and one or more side windows are defined in the first and/or second side surfaces.

主权项

1. An implant for implantation in a spinal facet joint, the implant comprising:
a distal leading portion having a distal end surface generally opposite a proximal end surface of a proximal trailing end; a first face having a first surface that is generally parallel with a second surface of a second face, the first and second faces extending between a portion of the distal leading portion and the proximal trailing end, the first and second surfaces having one or more textured features; a first side having a first side surface generally opposite a second side having a second side surface, the first side surface and the second side surface; one or more windows defined in the first surface generally opposing one or more windows defined in the second surface; and one or more side windows defined in the first side surface generally opposing one or more windows defined in the second side surface, the windows and side windows providing access to a hollow interior of the implant.
