Abstract
The treatment of osteoporotic vertebral compression fractures using transpedicular augmentation has grown significantly during the past two decades. Balloon Kyphoplasty allowed to restore vertebral height and to improve the deformity, but has several disadvantages related to the filler material used: the bio-cement. The aim of the current study is to investigate the mechanical behaviour of cadaveric fractured osteoporotic vertebral treated with a new filler material made by Spheres in Trabecular Titanium alloy (Ti6Al4V-ELI), under static loading conditions. The Strength of the VBs remain almost the same. So, the VBs maintain their physiological values after the kyphoplastic procedure with trabecular titanium sphere. The stiffness was instead significantly reduced in some VBs. This data can be affected to the limit of ex vivo study.
