摘要：
The present method includes the following steps: removing a portion of a previously implanted spinal arthroplasty device and attaching a revision component to a remaining portion of the previously implanted spinal arthroplasty device to alter a biomechanical characteristic of the implanted arthroplasty device. Another aspect of the invention provides a method of limiting motion between adjacent vertebrae including the steps of accessing an implanted spinal arthroplasty device comprising a cephalad component fixed to a first vertebra and a caudal component fixed to a second vertebra inferior to the first vertebra, the cephalad and caudal components having a range of motion between them, and attaching a revision component to the cephalad and caudal components to reduce the range of motion. The invention also includes revision devices for revising the biomechanics of implanted spinal arthroplasty devices.
