Abstract

Transforaminal lumbar interbody fusion (TLIF) cages are employed in lumbosacral spine surgery. These implants are made in Titanium and offer biocompatibility, high resistance to corrosion and a good mechanical performance. In the last years, Additive Manufacturing (AM) has been introduced in many biomedical applications, thanks to the possibility of improving complex geometry and customization for specific patient. In this regard, compensation of real mechanical behaviour is a critical issue to be investigated. The present work is focused on the evaluation of stress distribution for a 3D printed TLIF cage by means of non-contact measurements as Thermoelastic Stress Analysis (TSA). A suitable setup has been adopted to guarantee the correct loading application and an optical access to the sample.
