Abstract
Interbody cages for spinal stabilization having a frame that surrounds a central compartment suitable for retaining biological material, such as bone graft material. The central compartment acts as a spill-free bone and biologic compartment that allows a surgeon to introduce the interbody cage into the body in an effective manner without spilling the biological material. Methods for introducing the interbody cages are disclosed.
