Abstract

Abstract:

Objective　To investigate the value of computer aided design (CAD) in spinal deformity surgery.　Method　CAD operation group:32 patients with scoliosis, kyphosis, and spine hemivertebrae were enrolled from January, 2009 to July, 2011, underwent surgery with the help of computer aided design combined with 3D printing , and followed up for 12 months to 60 months. Control group：at the same period, 27 cases with scoliosis were cured by the conventional surgical methods with the surgery performed by the same doctors.The patients were also followed up. Surgical duration and other indicators were compared between the same groups by statistical analysis to demonstrate the superiority of the CAD.　Result　Compared with the CAD group, the surgical operation, amount of bleeding , accuracy of the screw placement,exposure time of X-ray, rectified rate of cobb angle has significant difference（P＜0.05）.　Conclusion　Surgical correction of scoliosis and kyphosis with the help of CAD can increase the accuracy and security of these operations and reduce the surgical duration.
