[Treatment of idiopathic scoliosis in children].

This is an update on the surgical and orthopedic management of scoliosis in children. After a review of the biomechanical factors underlying the scoliotic deformity in the three dimensions, methods and indications of conservative treatment combining physiotherapy and full-time or part-time bracing are discussed. Development of new segmental spinal instrumentation devices has modified the surgical treatment of scoliosis by allowing three-dimensional correction of deformities and obviating the need for postoperative immobilization in a cast or corset. Results of conservative treatment are analyzed in an original series of 56 children with progressive scoliosis treated when the angulation was still under 30 degrees. Mean follow-up since the end of treatment is 14 years. Results show that proper conservative treatment arrests progression and modifies the natural history of scoliosis. Outcome after surgical treatment is analyzed in an original and recent series composed of the 50 first children who had posterior surgery with the new Cotrel-Dubousset instrumentation. Results of anterior surgery (V.D.S. instrumentation), which is still indicated in some cases, are analyzed in an older series of 18 cases. When the deformities are too severe to allow conservative treatment, short segment fusion effectively corrects the scoliosis and reliably provides good cosmetic and functional results.
