Early Hemivertebra Resection of Congenital Hemivertebra in Very Young Children: A Randomized Clinical Study

Early diagnosis and early effective treatment of congenital hemivertebrae can correct the deformities.Therefore, traditionally, children with a clear diagnosis should be fixed with a brace to delay the aggravation of scoliosis and then undergo surgery after 5 years of age. The design of this study is to conduct a single-center randomized controlled study. Children aged 3-5 years old diagnosed as congenital hemivertebrae will be randomly divided into the early operation group and the control group. The early operation group will undergo posterior hemivertebra resection. The control group received brace plaster fixation to reduce the progression of scoliosis, and posterior scoliosis correction will be performed after the age was over 5 years old. The primary outcome measures are the length of spine surgery for the two groups of children. The secondary outcome measures are change of scoliosis cobb angle, by comparing preoperative and postoperative cobb angle changes. It is expected that the early treatment group will shorten the length of surgery due to the smaller degree of scoliosis. Our research is expected to broaden the age-adaptation of classic spinal surgery in the field of pediatric spine.
