In this article the results of surgical treatment of 150 patients with adult idiopathic scoliosis are presented. We used a rod instrumentation LSZ-3 of full and selective fusion of primary curve. Application of the core endocorrector LSZ-3 allowed to reduce the traumatism of surgical treat- ment and the risk of fatigue fractures of endocorrector components. This method improved both the physical adaptation of the patients after the operation and their quality of life.
