Publication number: 20090264939Abstract: A nuclectomy method for creating a nuclear cavity in an annulus located in an intervertebral disc space and for preparing the nuclear cavity to receive an intervertebral prosthesis. The method involves identifying a plurality of regions in at least a portion of the nucleus. A sequence for removing the regions is also determined. At least one annulotomy is formed in the annulus along an annular axis to provide access to the nucleus. A guide system is positioned relative to the annulotomy. The guide system is configured to limit motion of at least one surgical tool relative to the guide system. A portion of the nucleus is removed from a first region using the surgical tool. At least one of the guide system and the surgical tool are configured to remove a portion of the nucleus from a second region. A portion of the nucleus is removed from a second region using the surgical tool.Type: ApplicationFiled: September 27, 2007Publication date: October 22, 2009Inventors: Erik O.
