====== Interbody graft ====== Involves adding bone graft to an area of the spine to set up a biological response that causes the bone to grow between the two vertebral elements and thereby stop the motion at that segment. [[Lumbar interbody fusion]] is a common treatment for a variety of spinal pathologies. It has been hypothesized that insufficient mechanical loading of the interbody graft can prevent proper fusion of the joint. ---- ===== Cervical titanium cage ===== [[Cervical titanium cage]] ===== Cervical PEEK cage ===== [[Cervical PEEK cage]]
