Automated methods for Cobb angle estimation are of high demand scoliosis assessment. Existing typically calculate the from landmark estimation, or simply combine low-level task (e.g., detection and spine segmentation) with regression task, without fully exploring benefits each other. In this study, we propose a novel multi-task framework, named Seg4Reg+, which jointly optimizes segmentation net...

Methods Design: retrospective pre-post study. Protocol: in our database we searched for all patients who were prescribed a Sibilla, or Sforzesco Brace, 21h per day or more for AIS, 30-35° Cobb, more than 10 years old at first evaluation, and no previous brace treatment. We compared data from the last visit before beginning the brace, and the first visit after 6 months of brace treatment. Sforze...

Aim To evaluate the effectiveness of nighttime bracing in AIS. Methods: Inclusion criteria were patients diagnosed with AIS and skeletal immature. With an apex of the primary curve from TH7 and below and with a Cobb angel between 2045 degrees. The patients were asked to wear the brace at least 7-8 hours pr. night. No other previous treatments were accepted and a follow up at least 6 months out ...

BACKGROUND Numerous studies have attempted to quantify the correlation between the surface deformity and the Cobb angle without considering growth as an important factor that may influence this correlation. In our series, we noticed that in some younger referred children from the school-screening program there is a discrepancy between the thoracic scoliometer readings and the morphology of thei...

STUDY DESIGN A prospective longitudinal cohort. OBJECTIVE The objective of this study was to evaluate changes in caregivers' perceptions of health-related quality of life (HRQOL) and caregiver burden in children with severe cerebral palsy (CP) following spinal fusion. SUMMARY OF BACKGROUND DATA Progressive scoliosis is common in nonambulatory children with CP; the utility of spine fusion ha...

BACKGROUND Much attention has been paid to peak height velocity (PHV) as a possible predictor of curve progression in patients with idiopathic scoliosis (IS). The aim of this study was to analyze the relationship between the magnitude of the Cobb angle at PHV and scoliosis progression, defined as having surgery prior to skeletal maturity in female patients with IS. METHODS A retrospective rev...

BACKGROUND The shape of the torso in patients with idiopathic scoliosis is considered to reflect the shape of the vertebral column, however the direct correlation between parameters describing clinical deformity and those characterizing radiological curvature was reported to be weak. It is not clear if the management proposed for scoliosis (physiotherapy, brace, surgery) affects equally the sha...

BACKGROUND Patients with idiopathic scoliosis are exposed to approximately 25 radiographic examinations of their spine throughout the clinical follow-up using the Cobb angle. Several non-invasive and radiation-free methods have been proposed to measure scoliotic deformities, including the scoliometer. OBJECTIVES To measure the intra- and interrater reliability of the scoliometer measurements,...

OBJECTIVE A thoracolumbar burst fracture is usually unstable and can cause neurological deficits and angular deformity. Patients with unstable thoracolumbar burst fracture usually need surgery for decompression of the spinal canal, correction of the angular deformity, and stabilization of the spinal column. We compared two struts, titanium mesh cages (TMCs) and expandable cages. METHODS 33 pa...
