A mild and severe collapse of T10 treated with vertebroplasty or kyphoplasty was studied. Stresses on the endplates and intradiscal pressures were extrapolated to determine the stress distribution in the adjacent structures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The validation ensured a correct stiffness and a proper kinematic of each functional spinal unit. The results demonstrated that a consolidation following vertebroplasty caused slight variations of intradiscal pressures and stresses. If a kyphoplasty was performed after a mild collapse of the vertebral body, a 25% stress reduction on endplates was found. In cases of severe collapse, when a partial height restoration was achieved, a 15% stress reduction was obtained, while with a full recovery of the anterior wall of the collapsed vertebra, there was a further reduction of 40%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>To reduce the stresses on the adjacent endplates and the risk of fracture, the results suggest a kyphoplasty is to be preferred, trying to restore the initial vertebral body height.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.5301\/jabfm.5000287","type":"journal-article","created":{"date-parts":[[2016,4,4]],"date-time":"2016-04-04T05:55:16Z","timestamp":1459749316000},"page":"197-204","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":17,"title":["Vertebroplasty and Kyphoplasty for the Treatment of Thoracic Fractures in Osteoporotic Patients: A Finite Element Comparative Analysis"],"prefix":"10.1177","volume":"14","author":[{"given":"Claudia","family":"Ottardi","sequence":"first","affiliation":[{"name":"Laboratory of Biological Structure Mechanics, Department of Chemistry, Materials and Chemical Engineering \u201cGiulio Natta\u201d, Politecnico di Milano, Milan -
