Abstract:
AIM:Spondylolisthesis is a common spinal disease for adults but rarely found in children.In this study,the treatment effect of spondylolisthesis in 7 children with posterior pedicle screw system after 1 year was explored.METHODS:①Eight children patients with spondylolisthesis treated in Shengjing Hospital of China Medical University between January 1996 and December 2006 were selected including 4 males and 4 females.The average age was 12.25 years(range,8-14 years).According to Meyerding classification,7 cases were of stage Ⅰand one of Ⅳ.②Texas Scottish Rite Hospital(TSRH) posterior pedicle screw system was provided by Wego Ortho Co.,Ltd.,GB1Z type,titanium,No.200511028009.Of the 8 cases,4 were treated by TSRH posterior pedicle screw system,3 were treated via a Wiltse paraspinal approach with autogenous bone graft placed between the transverse processes of L5 and sacral ala in situ fusion,and 1 was not treated by operation.The informed consent of treatment was obtained from the patients.③The changes in the spinal radioactive imaging before and after operation,and the material and host biocompatibility were observed.RESULTS:①Seven of 8 cases were followed up.The mean time of follow-up was 56.6 months with a range from 13 to 111 months.②Three of 4 cases treated by TSRH were vertebral completely reduction with the stability of instrumentation about 75%(3/4),and the other one was partly reduction(about 85%).One person developed the progress again in the X-ray films at three weeks after operation.Three cases treated by Wiltse paraspinal approach with autogenous bone graft placed between the transverse processes of L5 and sacral ala in situ fusion healed well without the recurrence of lumbosacral spondylolisthesis and nonunion.CONCLUSION:TSRH is an efficient and safety option for the treatment of spondylolisthesis in children.
