Observational Study
Geometric morphometrics of adolescent idiopathic scoliosis: a prospective observational study.
Adolescent idiopathic scoliosis is the most prevalent type of scoliosis, and its consequences on the human torso have not been deeply studied. In spite of being a 3D condition, clinical management is circumscribed to 2D images among health-care professionals. GMM is a well-recognized tool in the study of 3D shape and symmetry. ⋯ The greater asymmetry observed in AIS was expectable, but the similarity of areas of asymmetry in both groups made us suspect of directional asymmetry in the human torso that could explain the high prevalence of right scoliosis observed in nature. The shape of the torso and the asymmetry should be considered as variables to study in AIS due to its correlation with Cobb angle. Progression of the deformities was not observed in our study, maybe due to short-term follow-up.

A cluster analysis describing spine and torso shape in Lenke type 1 adolescent idiopathic scoliosis.
The purpose of this work is to identify the variability and subtypes of the combined shape of the spine and torso in Lenke type 1 adolescent idiopathic scoliosis (AIS). ⋯ These clusters represent a new description of Lenke 1 AIS that comprises both coronal and sagittal measures of the spine combined with a measure of torso asymmetry. Automated identification of the clusters is accurate. The ability to identify subtypes of deformity, based on parameters that affect both the spine and the torso in AIS, leads to as better understanding of the totality of the deformity seen.

The purpose of this study was to utilize the National Readmission Database (NRD) to determine estimates for complication rates, 90-day readmission rates, and hospital costs associated with spinal fusion in pediatric patients with Marfan syndrome. ⋯ This study is the first to demonstrate on a national level the complications and potential risk factors for 90-day hospital readmission for patients with Marfan syndrome undergoing spinal fusion. Patients with Marfan syndrome undergoing spinal fusion often present with multiple medical comorbidities that must be managed carefully perioperatively to reduce inpatient complications and early hospital readmissions.

For fusion surgery in adolescent idiopathic scoliosis (AIS) consensus exists that a 2-year radiographic follow-up assessment is needed. This standard lacks empirical evidence. The purpose of this study was to investigate the radiographic follow-up after corrective surgery in AIS, from pre-until 2 years postoperative. ⋯ No statistically significant changes in major curve Cobb angle were found during postsurgical follow-up, or in adjacent non-fused segments. The findings of this study are not supportive for routine radiographs 2 years after fusion surgery in AIS patients.

Correction of severe idiopathic scoliosis poses surgical challenges. Treatment options entail anterior and/or posterior release, Halo-gravity traction (HGT) and three-column osteotomies (3CO). The authors report results with a novel technique of temporary short-term magnetically controlled growing rod (MCGR) as part of a posterior-only strategy to treat severe idiopathic major thoracic curves (MTC). ⋯ This is the first series of AIS patients that had temporary MCGR to treat severe thoracic scoliosis. A staged protocol including internal temporary distraction with MCGR after posterior release and definitive correction resulted in large MTC-correction and restoration of trunk height. Results indicate that technique has the potential to reduce the necessity for HGT and high-risk 3CO for the correction of severe scoliosis.
