Vertebral strength prediction from Bi-Planar dual energy x-ray absorptiometry under anterior compressive force using a finite element model: An in vitro study
Autor: Jean-Marc Valiadis, Sami Kolta, Julie Choisne, Wafa Skalli, Christophe Travert, Christian Roux
Publikováno v: Journal of the Mechanical Behavior of Biomedical Materials. 87:190-196
Finite element models (FEM) derived from qCT-scans were developed as a clinical tool to evaluate vertebral strength. However, the high dose, time and cost of qCT-scanner are limitations for routine osteoporotic diagnosis. A new approach considers usi

Publikováno v: Bone. 50:777-783
Bone size and shape play an important role in bone strength, as shown by biomechanical testing and clinical studies. Vertebral body dimensions determine vertebral body strength even after adjustment for bone mineral density. We have recently proposed

Publikováno v: Medical & Biological Engineering & Computing. 49:1355-1361
Patient-specific modeling could help in predicting vertebral osteoporotic fracture. The accuracy requirement for input data available in clinical routine is related to the model sensitivity. The objective of this study is to assess the relative impac
