Figure 7b. Resorption of nonunited graft material and hardware fracture. (a) Initial postoperative lateral radiograph demonstrates anterior plate and screw fixation of C4 to C5 with an intervertebral bone graft (*). Note the excellent graft incorporation at the levels of previous anterior fusion (C5 to C6 and C6 to C7); hardware was removed from those levels during surgical fusion of C4 to C5. (b) Extension radiograph obtained at 13-month follow-up demonstrates resorption of the graft material and fracture of the inferior screw (arrow).
