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.

doi : 10.1007/s00586-020-06652-9
Volume 30, issue 3, March 2021, Pages: 628 - 633
Adolescent idiopathic scoliosis (AIS) patients are exposed to 9–10 times more radiation and a fivefold increased lifetime cancer risk. Radiation-free imaging alternatives are needed. Ultrasound imaging of spinal curvature was shown to be accurate, however, systematically underestimating the Cobb angle. The purpose of this study is to create and cross-validate an equation that calculates the expected Cobb angle using ultrasound spinal measurements of AIS patients.

Comparison of different strategies on three-dimensional correction of AIS: which plane will suffer?
Tom P. Schl?sserKariman Abelin-GenevoisRené M. Castelein
doi : 10.1007/s00586-020-06659-2
Volume 30, issue 3, March 2021, Pages: 645 - 652
There are distinct differences in strategy amongst experienced surgeons from different ‘scoliosis schools’ around the world. This study aims to test the hypothesis that, due to the 3-D nature of AIS, different strategies can lead to different coronal, axial and sagittal curve correction.

Volume 30, issue 3, March 2021, Pages: 653 - 660
Knowledge on the factors affecting the correction rate (CR) aids in the surgical planning among severe idiopathic scoliosis (IS) patients. This study aimed to investigate the independent factors affecting CR among patients with severe IS (Cobb angle???90°) who underwent single-staged posterior spinal fusion (PSF).

Volume 30, issue 3, March 2021, Pages: 661 - 667
Preoperative shoulder balance is an important factor in determining the upper instrumented vertebrae (UIV). In adolescent and adult idiopathic scoliosis (AIS/AdIS) patients, we studied the intraobserver and interobserver reliability of spinal surgeons’ assessment of preoperative shoulder balance using X-rays (XR) and anterior/posterior photographs.
Estimation of plane of maximum curvature for the patients with adolescent idiopathic scoliosis via a purpose-design computational method
Hui-Dong WuChen HeMan-Sang Wong
doi : 10.1007/s00586-020-06557-7
Volume 30, issue 3, March 2021, Pages: 668 - 675
The coronal Cobb angle is commonly used for assessing the adolescent idiopathic scoliosis (AIS); however, it may underestimate the severity of AIS while the plane of maximum curvature (PMC) could be a promising descriptor for three-dimensional assessment of AIS. This study aimed to develop a computational method (CM) for estimating the PMC based on the coronal and sagittal images of the spine, and to verify the results with computed tomography (CT).
Radiographic scoliosis angle estimation: spline-based measurement reveals superior reliability compared to traditional COBB method
Peter BernsteinJohannes MetzlerMarkus Wacker
doi : 10.1007/s00586-020-06577-3
Volume 30, issue 3, March 2021, Pages: 676 - 685
Although being standard for scoliosis curve size estimation, COBB angle measurement is well known to be inaccurate, due to a high interobserver variance in end vertebra selection and end plate contour delineation. We propose a stepwise improvement by using a spline constructed from vertebra centroids to resemble spinal curve characteristics more closely. To enhance precision even further, a neural net was trained to detect the centroids automatically.
Deformity correction using proximal hooks and distal screws (PHDSs) improves radiological metrics in adolescent idiopathic scoliosis

doi : 10.1007/s00586-020-06529-x
Volume 30, issue 3, March 2021, Pages: 692 - 697
Adolescent idiopathic scoliosis (AIS) is a common type of idiopathic scoliosis. Previous studies reported that the incidence of intraspinal abnormalities among the presumed idiopathic scoliosis was 13–43%. Intraspinal abnormalities were also considered increasing the risks of progressing of scoliosis and neurological complications following scoliosis corrective surgery. The surgical strategy of presumed adolescent idiopathic scoliosis (PAIS) associated with intraspinal abnormalities remains controversial. The purpose of this study was to investigate whether one-stage posterior surgery safe and effective for the PAIS patients associated with intraspinal abnormalities.

The potential of spring distraction to dynamically correct complex spinal deformities in the growing child
Sebastiaan P. J. WijdicksJustin V. C. LemansMoyo C. Kruyt
doi : 10.1007/s00586-020-06612-3
Volume 30, issue 3, March 2021, Pages: 714 - 723
Current treatment of progressive early onset scoliosis involves growth-friendly instrumentation if conservative treatment fails. These implants guide growth by passive sliding or repeated lengthenings. None of these techniques provide dynamic correction after implantation. We developed the spring distraction system (SDS), by using one or multiple compressed springs positioned around a standard sliding rod, to provide active continuous distraction of the spine to stimulate growth and further correction. The purpose of this study was to determine feasibility and proof of concept of the SDS.
Long-term experience with simultaneous prone video-assisted thoracoscopic anterior spinal release and posterior spinal fusion in severe rigid pediatric spinal deformities
Chirag A. BerryViral V. JainAlvin H. Crawford
doi : 10.1007/s00586-020-06711-1
Volume 30, issue 3, March 2021, Pages: 724 - 732
While posterior-alone techniques have been successful for most pediatric spinal deformities, anterior spinal release may be useful for severe rigid deformities. Traditional lateral-positioned video-assisted thoracoscopic surgical release (VATSR) followed by prone posterior spinal fusion (PSF) has been criticized for adding extensive operative morbidity. We aimed to reduce its disadvantages by performing prone VATSR and PSF simultaneously and evaluate its long-term outcomes.

doi : 10.1007/s00586-021-06717-3
Volume 30, issue 3, March 2021, Pages: 740 - 748
Corrective surgery for scoliosis is a complex and challenging prospect for experienced spine surgeons due to the prolonged duration of surgery and the significant level of technical skill and expertise required. Traditionally, shorter operative time and lower blood loss have correlated well with improved outcomes and as such, efforts have been made to affect these metrics including the use of two attending surgeons for major cases in preference to one. This systematic review and meta-analysis assessed the available literature to further clarify the potential benefit that adopting a dual-surgeon approach offers over single-surgeon operations.

Progressive early-onset scoliosis raises major challenges for surgeons, as growth must be preserved. With traditional growing rods, the need for repeated surgery is associated with numerous complications, high costs, and heavy psychosocial burden on the patient and family. We assessed the safety and efficacy of a new one-way self-expanding rod (OWSER).

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.

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).
