Dose Reduction Protocol for Full Spine X-ray Examination Using Copper Filters in Patients With Adolescent Idiopathic Scoliosis

Conclusion. Whole spine radiographs using 0.2-mm Cu filters in patients with AIS could reduce radiation exposure more than 60% while preserving the image quality. Level of Evidence: 4

AbstractPurposeThe study aimed for unraveling the long-term health impact of cumulative radiation exposure from full-spine radiographs on children/adolescents with scoliosis.MethodsAll cohort, case –control or cross-sectional studies about radiation exposure to scoliosis patients with follow-up period as 20 years or more were included. Meta-analyses were performed for outcomes reported in two or more studies.ResultsA total of 9 eligible studies involving 35,641 participants between 1912 and 1990 fulfilled the inclusion criteria, including 18,873 patients with scoliosis and 16,768 controls as regional matched gen...

Adolescent idiopathic scoliosis (AIS) is a spinal deformity that causes the spine to bend laterally. Patients with AIS undergo frequent X-ray examinations to monitor the progression of the disorder by through the measurement of the Cobb angle. Frequent exposure of adolescents poses the risk of radiation-induced cancer. The aim of this research was to design and build a bespoke phantom representing a 10-year-old child with AIS to allow optimisation of imaging protocols for AIS assessment through the accuracy of Cobb angle measurements.

Adolescent idiopathic scoliosis (AIS) is a spinal deformity that can affect young children. It requires frequent exposure to X-rays to monitor the deformity, which can lead to the development of radiation-induced cancer later in life. The aim of this study is to test the accuracy of using scan projection radiography (SPR) in computed tomography (CT) scans for AIS assessment. This scanning mode delivers low radiation compared with conventional radiography.

AbstractAdolescent idiopathic scoliosis (AIS) is a three-dimensional (3D) spinal deformity. Current practice uses the Cobb method to measure spinal severity on postero-anterior (PA) radiographs. This method may underestimate spinal deformity and exposes patients to ionizing radiation, increasing the risk of cancer. This paper reports a new 3D ultrasound method using the voxel-based reconstruction technique with bilinear interpolation to reconstruct a 3D spinal image and measure true spinal curvature on the plane of maximal curvature (PMC). Axial vertebral rotation (AVR) was measured on the 3D image and utilized to estimate...

Study Design. Retrospective cohort study. Objective. Analyze risk factors associated with a non-home discharge following spinal fusions in adolescent idiopathic scoliosis (AIS). Summary of Background Data. Current evidence is limited with regard to which patient-level and provider/hospital-level factors predict a non-home discharge disposition following spinal fusions in AIS. Identifying these factors can allow providers to identify which patients would ultimately require facility care and can be discharged early to these facilities to reduce hospital costs. Methods. The 2012 to 2016 American College of Surgeons...

AbstractThe use of routine spinal X-rays within chiropractic has a contentious history. Elements of the profession advocate for the need for routine spinal X-rays to improve patient management, whereas other chiropractors advocate using spinal X-rays only when endorsed by current imaging guidelines. This review aims to summarise the current evidence for the use of spinal X-ray in chiropractic practice, with consideration of the related risks and benefits. Current evidence supports the use of spinal X-rays only in the diagnosis of trauma and spondyloarthropathy, and in the assessment of progressive spinal structural deformi...

Semin Hear 2018; 39: 321-333 DOI: 10.1055/s-0038-1666821This perspective explores common pediatric diagnoses that could present with central vestibular pathway dysfunction, leading to delays in motor development and postural control, and gaze instability. Specifically, the following diagnoses are considered: cerebral palsy, myelomeningocele, vestibular migraine, attention-deficit hyperactivity disorder, developmental coordination disorder, concussion, childhood cancer, congenital muscular torticollis, adolescent idiopathic scoliosis, and autism. Suggestions for clinical screening, vestibular function testing, and vestibula...

ConclusionsAn evaluation strategy with ATR measurements provides for a reliable, cost-effective and safety advantage in the monitoring of curve progression in both skeletally mature and immature patients with AIS. These findings suggest that stable ATR measurements are a safe and cost effective alternative to serial radiographs in the clinical monitoring of AIS. Recent evidence from 25 years of scoliosis treatment in Denmark noted a cancer rate 17 times that of an age-matched population. Thus, reducing radiation exposure during scoliosis monitoring using ATR measurements has important clinical significance for cancer risk reduction.

ConclusionsThe EOS system is efficient in limiting patient dose. The shielding of testes and the exclusion of eyes from the scan could allow to further reduce the dose.

[Image from]From Xtant Medical’s 510(k) extension to Varian Medical’s distribution deal, here are seven medtech stories we missed this week but thought were still worth a mention. 1. FDA extends Xtant Medical’s 510(k) for Calix C spinal implant Xtant Medical announced in an Aug. 9 press release that the FDA has cleared its product line extensions for the Calix-C cervical inter body cages. The clearance allows for two larger footprints to be added for use with allograft. The Calix-C Cervical Interbody Spacer is designed for spinal fusion procedures at level one in patients who are skeletally m...
