Abstract:
ObjectiveTo investigate the effects of the modified expanding suspended laminoplasty and posterior pedicle screw fixation on the perioperative indicators, postoperative neurological function and spinal stability in patients with spinal canal tumors.
MethodsThe clinical data of 128 patients with spinal canal tumors were retrospectively analyzed.Seventy-five were treated with the modified expanding suspended laminoplasty(group A), and 53 cases were treated with posterior pedicle screw fixation(group B).The operative time, intraoperative blood loss and incidence rate of postoperative cerebrospinal fluid leakage, and JOA score, JOA score improvement rate and spinal instability incidence after 3, 6 and 12 months of surgery were compared between two groups.
ResultsThe operative time, intraoperative blood loss and incidence rate of postoperative cerebrospinal fluid leakage in group A were significantly lower than those in group B(P < 0.05 to P < 0.01).After operation, the JOA scores in two groups significantly increased(P < 0.01).After 3, 6 and 12 of operation, the JOA score and JOA score improvement rate in group A were significantly lower than those in group B(P < 0.01), and the differences of the incidence rate of spinal instability were not statistically significant between two groups(P>0.05).
ConclusionsCompared with the posterior pedicle screw fixation, the modified expanding suspended laminoplasty can shorten the operation time, and reduce the amount of intraoperative bleeding and incidence rate of cerebrospinal fluid leakage of patients with spinal canal tumors.The two types of surgery have a good effect in stabilizing the spine after operation, but the posterior pedicle screw fixation has a large amount of trauma and bleeding, and affects the mobility of the spinal fixation segment.The best choice should be chosen according to the patient's specific situation.
