Abstract:
This article reviewed the literatures about degeneration at the segments adjacent to the fusional and instrumental segments. The hypertrophic degenerative arthritis of the facet joints, intervertebral instability and spinal stenosis were the common pathologic changes. The changes usually occurred at the upper segment of spinal fusion. The average time period for the development of adjacent segment degeneration might be shortened after spinal fusion with instrumentation. The main reason was stress and hypermobility increased at the adjacent segment and postoperative malalignment of the spine after spinal fusion.
