MATERIAL and METHODS: We retrospectively analyzed 23 children over 5 years old who were treated with spinal cord untethering in our hospital from January 2010 to January 2021 and who had complete medical data. X-rays were used to examine the child?s spine preoperatively, postoperatively, and at follow-up with frontal and lateral radiographs, and lumbosacral angle data were measured and analyzed.

RESULTS: A total of 23 children aged 5?14 years had their lumbosacral angles measured and analyzed with a postoperative followup of 12?48 months. The mean preoperative lumbosacral angle was 70.30 ± 9.04°, the mean postoperative lumbosacral angle was 63.34 ± 5.60°, and the mean lumbosacral angle at the last follow-up was 61.61 ± 9.14°. There was a statistically significant reduction in the lumbosacral angle in the children postoperatively and at the last follow-up compared to the preoperative period (p=0.002; p=0.001).

CONCLUSION: Spinal cord untethering can improve the inclination of the lumbosacral angle in children older than 5 years with tethered cord syndrome. Keywords : Children, Lumbosacral angle, Tethered cord syndrome, X-ray
