Fig. 3From: Finite element analysis of wedge and biconcave deformity in four different height restoration after augmentation of osteoporotic vertebral compression fracturesThe von Mises stress of the vertebral body, intervertebral disc, and facet joint under seven different postures of wedge fracture (a) and biconcave fracture (b). Note: neutral position (NP), flexion (FLEX), extension (EXT), left lateral bending (LLB), right lateral bending (RLB), left axial rotation (LAR), and right axial rotation (RAR)Back to article page
