title: [The mechanisms for the loss of correction in the surgical treatment of severe forms of scoliosis].
abstract: Of the 2719 patients presenting with grave forms of scoliosis who had undergone 4377 correction operations, 85 patients demonstrated serious complications in respect of loss of correction, with six of these having developed myelopathy in the long-term follow-up. Causes of the above problem included failure of internal fixation with distractors through the breakage of the construction or supporting structures of vertebrae and disturbances in external immobilization. As to its mechanism, loss of correction occurred because of transplant incapsulation or rearrangement of bone and plastic material, with the Loozer's zones, pseudarthroses, or defects in spondylodesis being developed.
