Abstract Background A retrospective study of staged surgery for severe rigid scoliosis. The purpose of this study was to evaluate the result of staged surgery in treatment of severe rigid scoliosis and to discuss the indications. Methods From 1998 to 2006 21 cases of severe rigid scoliosis with coronal Cobb angle more than 80 were treated by staged surgeries including anterior release and halo-pelvic traction as first stage surgery and posterior instrumentation and spinal fusion as second stage. Pedicle subtraction osteotomy PSO was added in second stage according to spine rigidity. Among the 21 patients 8 were male and 13 female with an average age of years rang from 4 to 23 years . The mean pre-operative Cobb angle was 80 -l45 with a mean spine flexibility of I 3 . Radiological parameters at different operative time points were analyzed mean time of follow-up 5I months .
