MODULICS CAGE;Vertebral body replacement is: a common indication performed in most orthopedic neurosurgical surgeries, always associated to posterior with/or anterior support. ;The ModulICS is indicated in any of the following conditions : To replace a deseased or injured vertebral body in tumor patients. To restore the height of a collapse vertebral body due to burst fractures To achieve anterior decompression of the spinal cord and neural tissues. To provide anterior stabilization following severe disc degeneration ; Same concept, design, diameters compared to the main competitors. However, it comes with additionnal features. ;Optimized sizing through a limited range of components Accuracy and ease of use;FEATURES - Titanium : biocompatibility / Strengh - MRI compatible. - Height adjustable before implantation - Fits the anatomy - Strong anchorage in cortical bone - Large room for graft material - Must restore the natural lordosis and kyphosis ;Maximized surface area Better stability in the cortical bone Better stress behavior vs endplate strength;No in-situ distraction Maximized graft compaction Contact between graft and endplates;Anterior surgery;Anterior approach;Anterior approach: lumbar spine;Anterior approach: indications;Anterior approach: advantages;MODULICS;Indications;The Modul’ICS range;Features Benefits;Competition Analysis;Harms cage (DePuy) The implant has to be cut ?Material is wasted ?Operative time is increased ?Cut proper angulations is difficult ?Does not foregive mistakes ?Instruments wears out quickly ?Need of extra instrument : caliper;?
