3D correction of AIS in braces designed using CAD/CAM and FEM: a randomized controlled trial
BACKGROUND Recent studies showed that finite element model (FEM) combined to CAD/CAM improves the design of braces for the conservative treatment of adolescent idiopathic scoliosis (AIS), using 2D measurements from in-brace radiographs. We aim to assess the immediate effectiveness on curve correction in all three planes of braces designed using CAD/CAM and numerical simulation compared to brace...
متن کاملCAD/CAM and biomechanical simulations vs. standard technique for the design of braces in adolescent idiopathic scoliosis: first results
Methods So far, 4 AIS patients were recruited. Two braces were built for each patient: 1) a standard TLSO designed using the plaster-cast method (Std Brace), and 2) a brace designed and fabricated using a biomechanical 3D finite element model personalized to the patient’s geometry, and a CAD/CAM software (NewBrace). NewBrace was optimized using a computational brace simulator that allows virtua...
متن کاملConservative treatment results of 39 patients with adolescent idiopathic scoliosis
Materials and methods 39 patients with AIS who did received a conservative treatment method included in the study allocated into three groups. 35 of our patients were female and 4 were male. 4 patients with 20°≥ Cobb angle enrolled into first group (exercise group). 24 patients did not want to receive an exercise programme so they included in 2. group (brace group). All of the patients worn CAD...
متن کاملEvaluation of Patient Outcome and Satisfaction after Surgical Treatment of Adolescent Idiopathic Scoliosis Using Scoliosis Research Society-30
Background: Adolescent idiopathic scoliosis (AIS) may lead to physical and mental problems. It also can adversely affect patient satisfaction and the quality of life. In this study, we assessed the outcomes and satisfaction rate after surgical treatment of AIS using scoliosis research society-30 questionnaire (SRS-30). Methods: We enrolled 135 patients with AIS undergoing corrective surgery...
متن کاملDevelopment of CAD/CAM Based Brace Models for the Treatment of Patients with Scoliosis-Classification Based Approach versus Finite Element Modelling
STUDY DESIGN Retrospective controlled cohort study comparing the in-brace correction of two samples of scoliosis patients with braces of different computer aided design (CAD). PURPOSE In-brace correction and compliance correlate with outcome. The more standardized CAD braces that are available should enable improved in-brace correction and outcome. This study compared recent CAD brace develop...
