Abstract

A spinal vertebral implant includes a substantially rectangular shaped base section made from a solid piece of bone. A nose section extends integrally from the substantially rectangularly shaped base section and preferably has a generally tapering shape to foster entry between adjacent vertebrae. The nose section tapers distally and inwardly from the base section to form a generally pointed or rounded distal tip portion and comprises a solid piece of bone. Serrated sides assist the implant in gripping adjacent upper and lower vertebrae and in being maintained therebetween. The serrated sides are angled in a manner that encourages the implant to be placed between the vertebrae and locked therebetween upon such placement. First and second implants may be placed into respective left and right sides of an intervertebral space. A method for placing one or more implants between the adjacent vertebrae comprises forming a slot configured to receive an implant and inserting the implant into the slot. Each slot is preferably formed from an upper slot portion and a lower slot portion in the posterior portion of adjacent upper and lower vertebrae, respectively. Instruments for performing the method include osteotomes, impactors, and spacers.

Independent Claims | See all claims (23)

  1. 1. A method for placing an implant between first and second vertebrae pursuant to a spinal surgical procedure, the method comprising: providing a spinal vertebral implant configured to foster bone fusion between upper and lower adjacent spinal vertebrae between which the implant is placed pursuant to a spinal surgical procedure; forming at least one slot in at least one of the upper and lower vertebrae, wherein the slot extends through a posterior surface of at least one of the upper and lower vertebrae; and inserting the implant into the slot such that the implant is maintained between the upper and lower vertebrae.
  2. 15. A method for preparing upper and lower adjacent vertebrae to receive a spinal vertebral implant therebetween, the spinal vertebral implant configured to foster bone fusion between the upper and lower adjacent spinal vertebrae, the method comprising: removing a substantial portion of an intervertebral disk extending between the vertebrae; and forming upper and lower slot portions in respective upper and lower vertebrae by placing sequentially sized spacers between the upper and lower vertebrae to form a collective slot, the slot configured to receive an implant therein.
  3. 19. A method for placing first and second implants between first and second spinal vertebrae from which a substantial portion of an intervertebral disk extending between the vertebrae has been removed, the method comprising: providing first and second spinal vertebral implants, each implant having a height that is significantly greater than the thickness thereof and configured to foster bone fusion between upper and lower adjacent spinal vertebrae between which the implant is placed pursuant to a spinal surgical procedure; forming first and second slots in at least one of the upper and lower vertebrae, wherein each of the first and second slots extends through a posterior surface of each of the upper and lower vertebrae; and inserting the first and second implants into respective first and second slots, such that the implants are mounted between the upper and lower vertebrae with minimal nerve root distraction.
  4. 20. A method for placing an implant between first and second vertebrae from which a substantial portion of an intervertebral disk extending between the vertebrae has been removed, the method comprising: removing a substantial portion of an intervertebral disk extending between upper and lower adjacent spinal vertebrae, wherein at least the anterior and lateral portions of the intervertebral disk are not removed; providing a spinal vertebral implant configured to foster bone fusion between the upper and lower adjacent spinal vertebrae between which the implant is placed pursuant to a spinal surgical procedure, the spinal implant comprising a substantially rectangular shaped base; providing a first slot portion in an upper vertebrae and a second slot portion in a lower vertebrae to form a collective slot extending from the posterior ends of the vertebrae towards the anterior ends of the vertebrae, the collective slot configured to receive the implant therein; and inserting the implant into the collective slot between the upper and lower vertebrae.
