Postoperative neck tilt in Lenke 1 and 2 AIS patients after correction surgery: a novel predictive index

Postoperative neck tilt (PNT) is a phenomenon in adolescent idiopathic scoliosis (AIS) patients which is distinct form shoulder imbalance. There were scarce studies performed to explore the risk factors for PN...

The objective of this work was to evaluate whether tetracycline (TC) in environmentally relevant concentrations was able to induce alterations to embryonic development and teratogenic effects in oocytes and embryos of Cyprinus carpio. For this purpose, an embryolethality study was conducted and the lethal concentration 50 (LC50) and effective concentration 50 of malformations (EC50) were calculated, and with these data the teratogenic index (TI) was determined. The main alterations to embryonic development and the teratogenic effects produced by TC on embryos of C. carpio were determined using the Kimmel and Hersem sc...

Authors: Weigl DM Abstract BACKGROUND: In non-ambulatory patients with cerebral palsy, the presence of scoliosis has a major impact on health and quality of life. The aim of this review is to raise awareness of caregivers from various professions to the extent of the problem, to explain the natural history of neuromuscular scoliosis and its pathophysiology, and to describe up-to-date optional conservative and surgical treatments.

Conclusion. rs11190870 in LBX1, a strong susceptibility SNP for AIS, may also be a susceptibility SNP for ASD. Thus, ASD and AIS may share a common genetic background. Level of Evidence: 4

Study Design. Retrospective case series. Objectives. To analyze the outcomes at skeletal maturity of patients treated with a single traditional growing rod (GR). To compare results of patients according to whether posterior spinal fusion (PSF) was performed at treatment completion. Summary of Background Data. Few studies examined the end results of GRs at skeletal maturity. There is no agreement on requirement of PSF at GR treatment completion. Methods. Clinical and radiological analysis of consecutive patients with severe and/or progressive scoliosis treated initially with traditional single GR. Group compariso...

Study Design. Retrospective study. Objective. To describe the treatment results of patients with severe ankylosing spondylitis (AS) kyphosis who underwent two-level osteotomy and correction surgery. Summary of Background Data. The best solution for the fixed kyphotic deformity of AS is corrective osteotomy. Many osteotomy options are available: pedicle subtraction osteotomy (PSO), Smith-Peterson osteotomy (SPO), and vertical column resection (VCR). These procedures all provide multiplanar deformity correction. Nevertheless, when the AS deformity is severe, an additional osteotomy site to get more correction, achiev...

Conclusion. Anxiety and mood are potentially modifiable risk factors that have the greatest impact on pre- and postoperative pain. These results can be used to identify higher-risk patients and develop preoperative therapeutic protocols to improve postoperative outcomes. Level of Evidence: 3

Study Design. Retrospective study. Objective. To compare syrinx characteristics, scoliotic parameters, and neurological deficits between Chiari I malformation (CIM) and idiopathic syringomyelia (IS) in the scoliotic population. Summary of Background Data. CIM and IS are common in neuromuscular scoliosis patients; however, differences in syrinx characteristics, scoliotic parameters, and neurological deficits between CIM and IS are unclear. Methods. Thirty-six patients with scoliosis secondary to CIM were enrolled retrospectively and matched with 36 IS patients for sex, age, scoliosis classification, and Cobb angl...

Study Design. A retrospective cohort, radiographic study. Objective. The aim of this study was to compare the progression of scoliosis owing to single hemivertebra (HV) during early childhood, according to the anteroposterior discordance obtained from the three-dimensional computed tomography (3D-CT) studies. Summary of Background Data. Previous studies have utilized 3D-CT for the classification of congenital spinal deformities and have introduced the concept of two types of deformity: unison and discordant anomalies. However, there have been no further studies on the clinical significance of these discordant defor...

This study examines national trends in the surgical management of lumbar spinal stenosis (LSS) in patients with and without coexisting scoliosis between 2010 and 2014. The study also examines revision rates for LSS procedures. Summary of Background Data. There is wide variability in the surgical management of patients with LSS, with and without coexisting spinal deformity. Methods. Data were obtained from the Healthcare Cost and Utilization Project's National Inpatient Sample Database. International Classification of Diseases 9th revision- Clinical Modification codes were used to identify all patients with a primary ...
