The Short Term Efficacy Of One-stage Posterior Hemivertebra Resection For Congenital Scoliosis

Objective: This is a study to discuss the short term efficacy ofone-stage posterior hemivertebra resection and causes of complications inperioperative period, to improve the efficacy of surgical treatment forchildren’s congenital scoliosis.Method: In this study,20cases diagnosed with congenital scoliosisdue to hemivertebra between October2008and October2012wereinvestigated retrospectively. There were9males and11females, mean agewas9years. All the cases underwent one-stage posterior hemivertebraresection.21hemivertebras were removed by surgery,11thoracic,9lumbarand1sacral. We compared the Cobb’s angle of pre-operation andpost-operation to discuss the causes of complications in perioperativeperiod by summarizing the medical records.Result: Each of the cases was followed up once a month for firsttrimester, then followed up for a march, at last followed up six months toone year at a time until adulthood. Taken anterior–posterior and lateralX-ray radiographs of total length of the spine while following up. All casesobtained8~48months of follow-up, an average of18.4months. The meanCobb’s angle was35.47°before surgery, was corrected to13.67°aftersurgery. The mean rate of correction was63.2%. In all cases, there were4appeared abdominal distension,3abdominal pain,1appeared local pain in back skin and positive Babinski sign,1appeared pulmonary atelectasis,1appeared numbness of lower limbs, and1appeared bedsore. No othercomplications appeared.Conclusions: One-stage posterior hemivertebra resection providesreliable short-term outcomes in children’s congenital scoliosis. Comparedwith anterior and posterior approaches, it can obtain excellent correctioneffect with less trauma, less blood loss and no lateral incision. Itscomplications are in the controllable scope and require less time forrecovery. We recommend that it could be carried out as early as2years old,as for the secondary deformities are relatively light, needing fixed shortersegment, and can obtain better effect of correction in early time.
