RESUMEN
[Objective]To explore the experience of the correction of severe kyphosis and kyphoscoliosis by total spinal osteotomy.[Method]To correct kyphosis and kyphoscoliosis by total spinal osteotomy and screws-rods internal fixation apparatus,then graft the bone.[Result]From 1984 to 2005,50 patients were cured with the way above.There were no neural injury observed.The clinical symptom was improved in some extent.All patients were follow up from 2 months to 15 years,averaged 2.4 years,and the postoperative X ray and CT scans verifies all screws were in a proper position.No cases of implant failure were observed,and all the patients had a solid bone fusion on radiographs taken 3 months after surgery.[Conclusion]The operation to correct severe kyphosis and kyphoscoliosis by total spinal osteotomy with efficient screws-rods internal fixation apparatus,not only have a larger operate area which made opreation easier and more safe,but combine osteotomy with internal fixation and finished at the same time,it is an efficient way to correct kyphosis and kyphoscoliosis.
