Rubinstein-Taybi syndrome with scoliosis

<p>Abstract</p> <p>Study Design</p> <p>Case report.</p> <p>Objective</p> <p>The authors present the case of a 14-year-old boy with Rubinstein-Taybi syndrome (RSTS) presenting scoliosis.</p> <p>Summary of Background Data</p> <p>There have been no reports on surgery for RSTS presenting scoliosis.</p> <p>Methods</p> <p>The patient was referred to our hospital for evaluation of a progressive spinal curvature. A standing anteroposterior spine radiograph at presentation to our hospital revealed an 84-degree right thoracic curve from T6 to T12, along with a 63-degree left lumbar compensatory curve from T12 to L4. We planned a two-staged surgery and decided to fuse from T4 to L4. The first operation was front-back surgery because of the rigidity of the right thoracic curve. The second operation of lumbar anterior discectomy and fusion was arranged 9 months after the first surgery to prevent the crankshaft phenomenon due to his natural course of adolescent growth. To avoid respiratory complications, the patient was put on a respirator in the ICU for several days after both surgeries.</p> <p>Results</p> <p>Full-length spine radiographs after the first surgery revealed no instrumentation failure and showed that the right thoracic curve was corrected to 31 degrees and the left lumbar curve was corrected to 34 degrees. No postoperative complications occurred after both surgeries.</p> <p>Conclusions</p> <p>We succeeded in treating the patient without complications. Full-length spine standing radiographs at one year after the second operation demonstrated a stable bony arthrodesis with no loss of initial correction.</p

Clinical Characteristics and Thoracic factors in patients with Idiopathic and Syndromic Scoliosis Associated with Pectus Excavatum

Introduction: The purpose of this study is to demonstrate the clinical characteristics and thoracic factors such as sternal tilt angle and Haller index in patients with idiopathic or syndromic scoliosis associated with pectus excavatum. Methods: We performed a retrospective review on a cohort of 70 patients (37 males and 33 females) diagnosed with idiopathic and syndromic scoliosis associated with pectus excavatum between 1985 and 2014. We investigated age, location and Cobb angle of the main curve, and thoracic factors including sternal deviation and tilting angle and Haller index using radiographs and computed tomography of the chest. Results: Patients' mean age at the first visit to our hospital was 10.3 years (1-18 years old). There were 41 patients with idiopathic scoliosis and 29 with syndromic scoliosis. Main curve locations were thoracic in 52 patients, thoracolumbar in 10, and lumbar in 8. The mean Cobb angle of the main curve was 45.0 degrees (11-109 degrees). The sternum was displaced on the left side in 72% of patients, central in 23%, and right in 5%. Mean sternal tilt angle was 12.4 degrees (2.3-34 degrees), and mean Haller index score was 4.9 (2.9-9.2). There was no significant correlation between Cobb angle and sternal tilt angle/Haller index. However, a significant difference was found between sternal tilt angle and Haller index. Conclusion: Most patients with both scoliosis and pectus excavatum have left side deviated sternum and a higher Haller index score; therefore this can negatively impact cardiac function. Prone positioning and the corrective force applied during scoliosis surgery as well as thoracic compression during cast or brace treatment may have a negative effect on cardiac function in these patients
