Resección de hemivértebra con técnica de eggshell en cifoescoliosis congénita: resultados en ni？os entre uno y siete a？os

introduction: hemivertebrae is associated with 50% of the congenital kyphoscoliosis and surgical treatment is usually required. objective: to evaluate clinical and radiographic results of hemivertebra resection with an eggshell procedure in children aged from one to seven years old. study design: retrospective review of patients who underwent hemivertebrae resection with an eggshell procedure. methods: from january 2006 to june 2008, seven hemivertebrae were resected in seven consecutive patients aged one to seven years old. a retrospective chart and a radiographic review were performed. the mean age at surgery was 3,2 years (range from one to seven years). the mean follow-up was 17 months (range from 7 to 35 months). cobb's angle in the coronal and sagittal planes preoperative and at follow-up, operating time, transfusion requirements and complications were analyzed. results: the mean pre-operative scoliosis cobb's angle was 35° and the average at follow-up was 19°. the mean correction at follow-up was 40%. the average of the pre-operative kyphosis cobb's angle was 42° and average at follow-up was 25°. rate of correction at follow-up was 33%. four patients required transfusion, with an average of 1,25 blood units. the average of operating time was 225 minutes. complications were encountered in two patients; one dural tear and one pedicular fracture. no neurological complications. all patients achieved solid fusion at follow-up. conclusion: hemivertebra resection with the eggshell procedure is a safe surgical technique and provides an excellent and immediate correction of congenital kyphoscoliosis at short term follow-up.
