Finite Element Investigation of Fracture Risk Under Postero-Anterior Mobilization on a Lumbar Bone in Elderly With and Without Osteoporosis

چکیده
Postero-anterior (PA) mobilization is widely used to manage low back pain by physiotherapists. The PA load applied through the spinous process of a vertebra. Low bone density counter-indication mobilization, whether may cause fractures in fragile vertebrae unclear. Therefore, aim this study was quantify role on fracture risk first lumbar vertebra subjected load. A finite element model lumbar (L1) an elderly female created predict mobilization. von Mises stress and minimum principal strain were as assessment indicators. Three different cases evaluated reflect healthy, osteoporotic, severe osteoporotic conditions assuming heterogeneous moduli based local converted from computed tomographic images. In condition under load, maximum largest compressive occurred pedicles process. These exceeded yield indicating high for failure. resulted also excessive healthy moderate conditions. can increase with osteoporosis. L1 are critical regions prone fracture. We recommend that it crucial be reduce force when applying
