Avoiding the foraminal stenosis – the role of core bearing geometry in cervical TDR: CAD simulation analysis

Richard Bostelmann, Mario Leimert, Jan Frederick Cornelius & Hans Jakob Steiger
Objective: There is a need for accommodation of the foraminae during physiological movement of the cervical spinal motion segment. If their volume is decreased too much, there will be irritation of the nerve root. By implanting artificial disc replacements the segmental motion could be preserved.
