26 A 47-year-old woman underwent a previous C4 corpectomy for cervicomyeloradiculopathy. Her extant swan neck deformity and symptoms worsened postoperatively. Preoperatively, the patient had cervical stenosis and kyphosis (Fig. 26-1). After a C4 corpectomy, her kyphosis increased, as exhibited on T2-weighted sagittal cervical magnetic resonance imaging (MRI) and sagittal cervical computed tomography (CT) reconstruction (Figs. 26-2 and 26-3). FIGURE 26-1 Preoperative cervical MRI with severe cervical spondylosis. Iatrogenic instability Revision and extension of her previous anterior cervical corpectomy and fusion with lateral mass plating posteriorly was undertaken (Fig. 26-4).
