Hybrid system for the surgical treatment of adolescent idiopathic scoliosis. Cienfuegos 2016-2017 (Preliminary study)

Background: adolescent idiopathic scoliosis is a three-dimensional deformity of the spine. Its surgical treatment is necessary to prevent the progression of the deformity, cardiorespiratory conditions and improve aesthetics. Objective: to characterize adolescent idiopathic scoliosis patients operated on Cienfuegos province, with a modified hybrid system Methods: a case series study of 15 patients operated on for adolescent idiopathic scoliosis with a hybrid instrumentation system modified by the author, taking into account the preoperative Cobb angle, immediate postoperative and one year after surgery, as well as its complications. Results: 14 girls and one boy were studied, with an average age of 13.9 years; Lenke's classification was used with eight patients of type 1, two of type 3, four of type 5 and one type 6 (there were no patients of types 2 and 4). The average preoperative curve was 59.1o at the immediate postoperative period, the average curve was 12.2o; with an average correction of 79.4%; the loss in degrees per year was 2.9o. The average surgical time was 190 minutes and a bleeding of 750ml. There were two complications, a radiculopathy and a superficial wound infection. Conclusions: the modified hybrid instrumentation system has a very good effectiveness in correcting the curve in adolescent idiopathic scoliosis.
