- Abstract:
- Objective To explore the efficacy of ultrasonic bone curette (UBC) assisted osteotomy for congenital spinal hemivertebral deformity in children.Methods The clinical and imaging data were analyzed retrospectively for surgical children with single hemivertebral deformities from March 2015 to October 2017.The same operator recorded the pre and post-operative values of operative duration (min),scoliosis Cobb’s angle (DEG),red blood cell count and hemoglobin.Then the postoperative drop rates of red blood cell count and hemoglobin and correction rate of scoliosis were calculated.And the intraoperative injury extents of pleura,nerve root,dura and spinal cord were recorded.The eligible cases were divided into UBC (n=24) and non-UBC (n=22) groups based upon the intraoperative application of UBC or not.There were 14 boys and 10 girls with an average age of (36.0±7.7) (23-67) months in UBC group versus 13 boys and 9 girls with an average age of (40.2±8.2)(22-68) months in non-UBC group.Results No significant inter-group difference in operative duration (t=1.301,P>0.05).The drop rate of red blood cell count decreased significantly lower in group UBC than that in non-UBC group (t=2.279,P<0.05).And the drop rate of hemoglobin decreased significantly lower in UBC group than that in non-UBC group (t=2.367,P<0.05).No significant inter-group difference existed in correction rate of scoliosis (t=0.569,P>0.05).One case of pleural injury was present in each group.There was no occurrence of nerve root,spinal cord or epidural injury.Conclusion For children with congenital hemivertebrae deformity,no significant difference exists in corrective efficacy,operative duration and postoperative complications between UBC versus traditional osteotomy.However,there is less hemorrhage during UBC osteotomy.
