Core Tip

Core tip: The spontaneous cervical apophyseal joint fusion is rare and only seen in juvenile type rheumatoid arthritis, where spontaneous fusions of more than three cervical segments are extremely uncommon. We present a patient with fusion of all but C6-C7 level. The single mobile segment became highly unstable, producing mechanical pain with symptoms of myelopathy. Prior to the surgery, awake fiber-optic intubation was used. Surgical intervention began with the anterolateral approach to the cervical spine performing decompression, insertion of cage and anterior vertebral plate and screws, followed by posterior approach and fixation. Care was taken to restore sagittal balance.
