Fig. 31.7. Lateral X-ray of a patient following a cervical laminectomy supplemented by a posterior fusion with fixation. The lateral mass screws have been placed into the lateral masses of C3, C4, C6 and C7. The facet joints are obliterated from C3-C4 to C5-C6, but remain patent at C6-C7, suggesting a non-union at the latter.

graft migration and fixation failure [24]. Evaluation of the results of anterior fusion have indicated that there is an incidence of collapse across the grafted segment, referred to as subsidence, and an incidence of graft extrusions. Obviously, the extrusion of a graft can result in a non-union and esophageal obstruction. Subsidence can produce a kyphotic cervical deformity, which predisposes to axial pain and, in more extreme circumstances, neurological complications. Many factors are involved in the likelihood of graft subsidence and/or extrusion, including the type of graft, its length and cross-sectional size and its positioning. Patient factors, including the configuration of the spine, the segment of spine involved in the fusion and the bone quality, also can influence the likelihood of subsidence. The use of a plate and the characteristics of the given plate utilized can
