Analysis of Results and Complications in Patients with Scheuermann Disease Treated with Posterior Fixation

Abstract

Introduction The selection of fusion levels in thoracic kyphosis been controversial, the incidence of juvenile kyphosis ranges from 1 to 8% being more common in males. Patients and Methods This study is a retrospective study case series type, level of evidence IV. We evaluated 15 patients with Scheuermann disease treated with posterior transpedicular fixation and osteotomies. Overall, two cases were excluded for not meeting the minimum monitoring time 2 years. The average age at time of surgery was 16.2 years. Patients were evaluated clinically and radiologically pre- and postsurgery to assess results and determine common factors of complications. Results In the series studied found that the percentage correction achieved was 49%, with a loss of correction 3 degrees at follow-up, the incidence of PJK was 23%, two of three patients presented the following factors in common: apex above T5, cervical hyperlordosis, SVA more than 4 cm, increased pelvic incidence, stiffness deformity, proximal fixation with hooks above T3, in the third case ended with pedicle screws. Conclusion Transpedicular fixation system and posterior spinal osteotomy is effective for the treatment of kyphosis by Scheuermann disease; the power of this type of correction techniques may arise in the pediatric population increased incidence of proximal junction kyphosis in patients with highest apex, curve stiffer, cervical hyperlordosis, and lower percentage of correction.
