STUDY DESIGN: A retrospective study. OBJECTIVE: To evaluate the surgical outcomes of posterior @entity24148 resection and short segment fusion with segmental pedicle screw fixation in @entity1635 in @entity1 younger than 10 years. SUMMARY OF BACKGROUND DATA: This is the first long-term follow-up on surgical outcomes of posterior @entity24148 resection and short segment fusion using segmental pedicle screw fixation in @entity1 younger than 10 years with @entity1635 . METHODS: @entity1 with @entity1635 (n = 18) younger than 10 years at the time of the surgery were treated by posterior @entity24148 resection and bilateral pedicle screw fixation. The mean age at the time of surgery was 6.6 years (range, 2.6-9.8 yr). They were retrospectively studied with a mean follow-up of 11.4 years (range, 7.1-17.3 yr). RESULTS: The mean Cobb angle of the main curve was 34.4   before surgery, 8.6   after surgery, and 12.9   at last follow-up. In the compensatory cranial curve, the preoperative Cobb angle of 14.5   was corrected to 5.9   postoperatively and was 8.4   at last follow-up. In the compensatory caudal curve, the preoperative Cobb angle of 17.4   improved to 4   postoperatively and 6.6   at last follow-up. There were no crankshaft phenomena and no clinical and radiographical features suggestive of @entity612 during follow-up. There were no major @entity16 related to the pedicle screws. CONCLUSION: Posterior @entity24148 resection after pedicle screw fixation in @entity1635 is a safe and effective procedure that can achieve rigid fixation and deformity correction and restore spinal balance. This study showed that early posterior @entity24148 resection of @entity1635 before structural changes occur above or below can reduce fusion length, prevent curve progression, and effectively achieve a more satisfactory correction without hazardous iatrogenic @entity612 , crankshaft phenomena, or @entity16 . LEVEL OF EVIDENCE: 3.
