WebSpinal interbody fusion is a standard and accepted method for spinal fusion. Interbody fusion devices include titanium (Ti) and polyetheretherketone (PEEK) cages with distinct biomechanical properties. Titanium and PEEK cages have been evaluated in the cervical and lumbar spine, with conflicting results in bony fusion and subsidence. WebSome fusion procedures involve the insertion of a spinal stabilization device that is performed in conjunction with the placement of an interbody fusion device. Spinal stabilization devices, pedicle based, include segmental and non-segmental spinal instrumentation which provide stabilization to the posterior spine via the pedicles. 2 …
