IMPLANTABLE BONE PLATE SYSTEM AND RELATED METHOD FOR SPINAL REPAIR
First Claim
1. A system for establishing and securing adjacent vertebrae in a defined spacial relationship prior to the excision and repair of damaged tissue, said system comprising:
- at least one distraction device configured for temporary placement between adjacent vertebrae and engaging upon opposing inferior and superior end plate surfaces of the adjacent vertebral bodies for achieving a desired spatial relationship between the vertebrae;
at least one implantable vertebral frame configured to span between the adjacent vertebrae, the frame being configured to attach to each of the adjacent vertebra while the distraction device is in place to postoperatively maintain the desired spatial relationship between the vertebrae after the distraction device is removed, the frame having at least one internal operating aperture there-through for providing access to at least one intervertebral disk space, the aperture sized to fit over the distraction device;
at least one interbody repair implant sized in relationship to the aperture of the frame to fit there-through and into the intervertebral space to compressively engage opposing inferior and superior surfaces of the adjacent vertebral bodies as the implant is being inserted; and
at least one retention member attachable to the frame to cover at least a portion of the aperture.

Abstract
A system for performing surgical repair of the spine includes a distractor and a permanently implanted bone plate system. A surgical repair methodology is also disclosed that employs an implanted bone plate system with a substantially void internal volume which is attached to adjacent vertebrae subsequent to the distraction and/or adjustment of curvature of the vertebrae and prior to the excision of disc and/or end plate tissue through the bone plate. The device further facilitates the subsequent delivery of an interbody repair device for the purpose of either fusion or dynamic stabilization, such as by disc arthroplasty. The plate may be permanently implanted, such as when a fusion between the attached vertebral bodies is desired, but it need not be permanently implanted.
