Abstract
Several fusion techniques of the cervical spine have been well described. The use of cervical interfacet spacers as a method of subaxial fusion is relatively new with limited but promising results. Given its anatomic morphology, the cervical interfacet space has been advocated as a strategic location for fusion given its relatively large size and surface area, firmness, and biomechanical strength. Facet spacers can be placed rather easily, safely, and quickly. Cervical interfacet spacers can be utilized with or without supplemental fixation. The pathogenesis of cervical spondylosis, the anatomic morphology of the facet, initial cervical interfacet graft design, radiographic outcomes of the intervertebral foramina, clinical outcomes, and technical pearls of facet fusion using interfacet grafts are described in this chapter. A clinical scenario using cervical interfacet spacers as a fusion technique in a patient with symptomatic pseudoarthrosis from a prior anterior cervical discectomy and fusion is provided.
