Internal fixation of the spine in the surgical treatment of scoliosis.
Progressive idiopathic scoliosis, despite the good effects of treatment by kinesitherapy and corrective corsets, continues to pose a complicated problem in planning surgical procedure. On the one hand, the steady growth and improvement of systems for three-plane correction and fixation of scoliosis improves the radiological and clinical outcome; on the other hand, three arises the necessity to choose the surgical procedure and system of implants appropriate for the given type, localization, and angular dimensions of the curvature. The problems faced by the operating surgeon include not only making the right choice of implants, but also arranging the transpedicular screws and hooks at the proper strategic points along the curvature of the spine.<br /> On the basis of clinical material from 200 patients surgically treated for idiopathic scoliosis, the authors present surgical solutions and analyze various implant systems (CD-HORIZON, DERO, STRYKER), made of steel or titanium, for three-plane correction and fixation of the spine. Attention is called to the application in the lumbar spine of transpedicular screws, which improve the correction and fixation of the spine and reduce the amount of instrumentation needed, while assuring the essential horizontal arrangement of the lower lumbar vertebrae.<br /> The authors' own experience shows that modern systems for three-plane correction and fixation of the spine in scoliosis exceeding 750, despite spondylodesis, do not assure the proper correction and biomechanical value, in comparison to the Wisconsin method, which combines BW distraction with Luque intersegmentary fixation.
