Multilevel lumbar fusion usually requires a large quantity of iliaccrest bone graft but the supply is usually insufficient, so an alternative bone graft substitute for autograft isneeded. This prospective study investigated the efficacy of calcium sulfate bycomparing the fusion rates between the experimental material calcium sulfatepellets with bone chips from laminectomy and autologous iliac bone graft inlong segment three-or four-level lumbar and lumbosacral posterolateralfusion. Forty-five patients with degenerative scoliosis or spondylolisthesisreceived multilevel spine fusion and decompression. The experimental materialof calcium sulfate pellets with decompression bone chips was placed on theexperimental side and the iliac crest bone graft was placed on the controlside. The fusion status was assessed radiographically at three-month intervals,and solid fusion was defined as a clear continuous intertransverse bony bridgeat all levels. The average follow-up period was 34.4 months. Twenty-nine64.4% patients showed solid fusion on the experimental side and 39 86.7%patients on the control side. The overall fusion rate was 86.7%. A statisticallysignificant relation was found betweenthe two sides with the Kappa coefficient of agreement of 0.436. Compared to the control side, the fusion rate of experimental side issignificantly reduced p = 0.014. The fusion ability of autograftis higher than the experimental material in multilevel lumbar posterolateralfusion. However, the overall fusion rate of calcium sulfate pellets is improved,compared with previously reported rates, which suggested that such material maybe considered as an acceptable bone graft extender.
