Sagittal (Fig. 2a) and transversal (Fig. 2b) T1- and T2-weighted magnetic resonance images showed a free herniated cervical disc severely compressing the spinal cord from central at C3/4 level and no bleeding of the retropharyngeal space.
Perioperative view and post-operative radiograph. Perioperative view (a) and lateral X-ray taken 3 years after surgery showing bone healing. The implants are in correct position (b).
