Two-step surgical correction of idiopatic scoliosis 3-4 of grade

We report the results of two-step surgical correction of 75 patients with scoliotic deformation of vertebral columns. The first step is surgical correction by expanding endocorrector. In the second step expanding endocorrector replaced by stable screwed system. Our method offered the possibility of primary surgical correction of scoliosis in the period of rapid growth without enbarrassing the growth of the vertebrum. Consequently, the method allowed escaping the disease progression, severe vertebral columns deformation and failure of compensation. By the second step we perform additional correction and reducing the intraoperative trauma.
