These fi ndings indicate that resorption of spinous nonfusion interspinous device implantation. processes because of a result of implant loosening, inhibit the Summary of Background Data. Clinical effectiveness of the targeted load redistribution through the PEEK nonfusion interspinous PEEK nonfusion spine implant Wallis (Abbott, Bordeaux, France; device in the lumbar spinal segment of the rat. This leads to reduced now Zimmer, Warsaw, IN) is well documented. However, there is long-term stability of the implant in the animal model.
