Long-term results after the one-stage posterior-only surgical correction of thoraco-lumbar kyphoscoliosis in congenital spine deformity caused by two ipsilateral hemi-vertebrae

摘要

A 8 years old girl with kyphoscoliosis due to T6, 11 and L1 HV. Radiographs images and CT images were obtained preoperatively, which shows T11 and L1 full segmentation HV caused kyphoscoliosis (a, b, e), less flexibility and very rigid curve (c,d). Postoperative PA and lateral radiograph, she was treated with posterior L11, L1 HV resection with unilateral fusion (f,g). PA and lateral radiograph at 46 months follow-up show that correction and trunk balance are well maintained (h,i). Implants removal was required in 6 years after surgery. Final PA and lateral radiograph at 84 months follow-up show that residual curve and trunk balance are stable (j,k)
