Abstract:
Objective To compare the modified expanding suspended laminoplasty and posterior pedicle screw fixation applied in lumbar intraspinal tumors and evaluate operation,complications,postoperative neurofunctional improvement and lumbar lumbar stability in the two groups.Methods We made a retrospective analysis of the clinical data of 1 14 cases of lumbar intraspinal tumors, including 66 cases of modified expanding suspended laminoplasty and 48 cases of posterior pedicle screw fixation.We compared the operation time,operation bleeding volume,and incidence of postoperative cerebrospinal fluid leakage in the two groups.We also analyzed the lumbar instability and spinal cord injury score standard by the Japanese Orthopedic Association (JOA)between the two groups at 3,6, 12,and 24 months after operation.Results The results of modified expanding suspended laminoplasty group were significantly better than those of posterior pedicle screw fixation group in operation time, operation bleeding volume and incidence of postoperative cerebrospinal fluid leakage (P < 0.01 ).The lumbar instability did not significantly differ between the two groups (P >0.05).At 3,6 or 12 months after the operation, changes in the increase of JOA score of the two groups had no significant difference (P > 0.05 ).However,24 mouths after the operation,the group of posterior pedicle screw fixation had significantly improved JOA score compared with that in the modified expanding suspended laminoplasty group.Conclusion Both the modified expanding suspended laminoplasty and posterior pedicle screw fixation have a favorable outcome of postoperative lumbar instability and neurofunction.And posterior pedicle screw fixation is superior to modified expanding suspended laminoplasty in improving neurofunction.
