A Case of Successful Foraminotomy for Severe Bilateral C5 Palsy following Posterior Decompression and Fusion Surgery for Cervical Ossification of Posterior Longitudinal Ligament

Figure 1

Preoperative radiological findings. (a) and (b): mixed type ossification of the posterior longitudinal ligament was observed on the lateral view of the cervical spine radiograph and sagittal view on computed tomography (CT). Alignment was lordotic and ossification did not exceed the “K-line.” (c): Foraminal stenosis was detected at bilateral C4/5 (1.5 mm on the left side and 2.5 mm on the right side) on axial view CT. (d): high-intensity areas in the spinal cord were not evident on magnetic resonance imaging.
