Efficacy of one-stage posterior hemivertebrectomy and short segment fusion for congenital hemivertebra malformations:a multicenter clinical study
摘要
Abstract
Objective To evaluate the efficacy of one-stage posterior hemivertebrectomy and short seg-ment fusion for congenital hemivertebra deformity in children at multiple medical centers.Methods This ret-rospective study included 35 children with single-level thoracic or lumbar hemivertebra who undergoing one-stage posterior hemivertebrectomy and short segment fusion at six medical centers between May 2016 and March 2021.The follow-up period was at least 2 years.General profiles,measurements of coronal main curve Cobb an-gle,proximal compensatory curve,distal compensatory curve,coronal balance,sagittal segmental kyphosis angle and complications were recorded at preoperation,postoperation and final follow-up visits for evaluating surgical outcomes.Results There were 18 boys and 17 girls with hemivertebra in T2-10(n=10),T11-L2(n=17)andL3-5(n=8).Average number of fused segments was 2.4.Operative age was(4.5±2.6)year and follow-up period(42.6±17.6)month.Preoperative coronal main curve Cobb angle was(37.6°±9.0°),post-operative angle(9.0°±6.4°)and final follow-up angle(13.3°±11.1°).Correction rates at postoperation and final follow-up were 76.1％and 64.6％.Correction rates of proximal compensatory curve and distal com-pensatory curve were 44.4％and 57.1％.Correction rate of segmental kyphosis was 37.2％.Significant differ-ences existed in postoperation and final follow-up coronal main curve Cobb angles,proximal compensatory curve,distal compensatory curve and sagittal segmental kyphosis angle as compared with preoperative values(P＜0.05).Complications included pedicle cutting(11.4％,4/35),deformity progression(8.6％,3/35)and infection(2.9％,1/35).No neurological complication was reported.Conclusions One-stage posterior hemivertebrectomy and short segment fusion are both safe and effective for treating single-level thoracic or lum-bar hemivertebra deformities in children.This surgical approach directly addresses the underlying cause of de-formity and preserves spinal growth and function.Nevertheless,meticulous cares and proactive preventions of postoperative complications,such as pedicle cutting and deformity progression,are necessary.关键词
