| Abstract | | Background. 33 patients were operated with delayed two-stage procedure because of severe scoliosis between 1994 and 2004 in Orthopaedic Hospital I/aldoltra. They represented 7,2% of our patients operated for scoliosis. The diagnoses ihcluded severe idiopathic scoliosis, neurofibromatosis, congenital and neuromuscular scoliosis. The mean age at operation time was 12 years (range Syears 1 month to 20 years). Follow up was 3 years 8 months (range 5 months to 10 years). Preoperatively the mean scoliosis angle was 70,6° (ranged 40°to 110°). All patients underwent first an anterior release, average number of intervertebral levels fused was 4,9. The second stage which took place 7 to 10 days later, consisted of posterior spinal fusion and instrumentation. Reduction of mean scoliosis angle was 31,6° (range 15° to 62°). Postoperative morbidity includes 3 complications, all of these resolved completly and well. Conclusions. To our opinion delayed two-stage procedure in selected patients an effective correction of scoliosis can be achived.
