【Abstract】 Objective To investigate the curative effect of posterior osteotomy correction and internal fixation on the resting stage of spinal tuberculosis kyphosis and side convex deformity in children.Methods 44 children younger than 16 years with resting stage of spinal tuberculosis kyphosis were treated with posterior osteotomy correction and internal fixation. The sagittal kyphotic Cobb 's angles, coronal kyphotic Cobb 's angles, sagittal trunk shift and VAS scale were observed. Results 44 children successfully completed surgery and completely followedup. The followup period did not occur bone resorption, bone non-union and pseudarthrosis. The sagittal kyphotic Cobb′s bending angle, coronal kyphotic Cobb′s bending angle and sagittal trunk shift before and after treatment were different (P＜005). 95% confidence interval of VAS scale before operation (0573~0734) and that of after operation (0377~0497) and last followedup (0355~0465) had not repeated interval (P＜005). 95% confidence interval of VAS scale after operation and last followedup (0355~0465) had repeated interval (P>005). 95% confidence interval of VAS scale before operation (0573~0734) and that of last followedup (0355~0465) had not repeated interval.Conclusion It is effective and safe to treat quiescent stage of spinal tuberculosis kyphosis and side convex deformity in children with posterior osteotomy correction and internal fixation.
