title: [One-stage anteroposterior hemi-vertebra resection and segmental internal fixation for young children with congenital scoliosis].
abstract: OBJECTIVE
  to discuss the feasibility and efficacy of one-stage anteroposterior hemi-vertebra resection and segmental internal fixation for young children with congenital scoliosis.
  
  
  METHODS
  thirty-five patients undergoing one-stage anteroposterior hemi-vertebra resection and segmental internal fixation were retrospectively studied. The mean followed-up period was 5.3 years (range: 1.2 - 8.7). The Cobb's angle of scoliosis at pre and post-operation was compared.
  
  
  RESULTS
  all children's parents were satisfied with the outcome. The Cobb's angle of scoliosis was corrected from (42.5 ± 6.7)° to (16.2 ± 3.2)° at post-operation. The coronal correction rate was 64.7%. The angle of kyphosis improved from preoperative (33.5 ± 5.2)° to postoperative (13.3 ± 5.6)° in 14 cases. Operative duration was 210 - 280 minutes with an average of 240 minutes. The intra-operative blood loss was 80 - 200 ml with an average of 120 ml. There was no significant correction loss at follow-up. No neurological complication, infection or pedicular fracture was reported.
  
  
  CONCLUSIONS
  the procedure of one-stage anteroposterior hemi-vertebra resection and segmental internal fixation is a safe and effective treatment for scoliosis by congenital hemi-vertebra in young children. A satisfactory correction may be achieved with a short fusion segment.
