Long-Term Follow-up Of CDI Transpe Dicular Fixer, Single FSU Fusion And Three Column Bone Grafting In Lumbar Spo Spondylolysis And Spondylolisthesis

OBJECTIVE: There are lots of surgical methods to treat the Lumbar Spondylolysis and spondylolisthesis . So far , only short - term results are available in the titerature . we make a long-term fouow-up of CDI transpedicular fixer and three-column bone grafting in lumbar spondylolysis and spondylolisthesis , to investigate it's Long term clinical outcome and influence at the odjacent FSU.METHODS : We have used short -rod CDI to treat the patients suffered from the lumbar spondylolysis and spondylolisthesis and make a follow - up over five years. The changes in the Japanese Orthopedic Association scoreandradiographic finding (AS , PS, DI , traction spur) were enaluated between preoperation , one year after operation and 5.3 years after operation.RESULTS: By statistical analysis, the AS, PS, DI and JOA score of the fusion segment are no difference between 1 year and 5.3 years after opevation , but they porfect remarkably than preoperation . the DI of adja-cent segment are no difference betweem preoperootion , 1 year afrter operation and 5.3 years affer operation.CONCLUSIONS: This study demonstrated that three-column fusion and CDI fixation had remarkable advantage in the treatment of lumbar spondylolysis and spandylolisthesis , and should be recommended extensively in the clinical works.
