Clinical and Radiological Outcomes of Posterior Cervical Fusion Supplemented With Interfacet Spacers

The use of Cervical Interfacet Spacers is a relatively novel technique shown to be useful for posterior fusion to address symptomatic pseudoarthrosis (fusion failure) after anterior cervical arthrodesis \[2\]. CIS have a relatively large osteoconductive surface area and are placed under tension in the interfacet space, which together favorably influence bony fusion \[2\].
