Comparison of the DIERS Formetric 4D Scanner and Plain Radiographs in Terms of Accuracy in Idiopathic Scoliosis Patients

IntroductionComparison of the DIERS Formetric 4D Scanner and plain Radiographs in terms of accuracy in AdolIdiopathic Scoliosis (AIS) Patients. This project aims to determine the accuracy of the DIERS scanner and help decide whether it could be used instead of radiographs for some, or all, AIS patients.Material and MethodsTwo patient lists were combined; both patients who underwent an operation between 2011–2014 and patients on the Spinecor bracing program. Only preoperative radiographs were used of the operative group. Both DIERS Formetric scan and radiograph were be taken on the same day to prevent time related changes to scoliotic curve. Patients were excluded if they had had an operation to treat their scoliosis. Patients with braces were included so long as their X-ray was of them not wearing the brace. There was no restriction on BMI. Some patients had a double curve (thoracic and lumbar) and it was decided to only compare the greater curve. The radiographs were assessed to show the Cobb angle and t...
