Post-laminectomy segmental hypermobility as well as appositional ossification were suggested by many authors to contribute to the unsatisfactory long-term results of laminectomy. The aim of this study was to find out whether segmental instability, among other factors, influences the degree of appositional ossification following laminectomy. ⋯ Simultaneous lumbar fusion with laminectomy is proved to be associated with less appositional ossification. Therefore lumbar fusion should be considered when planning surgery for spinal stenosis.
