Abstract
Transforaminal lumbar interbody fusion(TLIF)cages are employedin lumbosacral spinesurgery. These implants are madein Titanium and offerbiocompatibility,high resistance to corrosionand a good mechanical performance. In the last years, Additive Manufacturing (AM) has been introducedin many biomedical applications, thankstothe possibility ofimprovingcomplex geometry and customization for specific patient. In this regard, compensation of real mechanical behaviour is a critical issueto be investigated. The present work is focused on the evaluationof stress distribution for a 3D printed TLIF cage by means of non-contact measurementsas Thermoelastic Stress Analysis (TSA). A suitable setup has been adopted to guarantee the correct loading applicationand an optical access to the sample| File | Dimensione | Formato | |
