Photo Quiz: Cervical Spine Anomaly

摘要

A 32-year-old man presented for an evaluation of his cervical spine to determine whether he had the same congenital anomaly that had been diagnosed in his three-year-old daughter; his daughter required surgery. Approximately one half of patients with atlantooccipital fusion develop instability. 4 Affected patients may have headache, neck pain, limb numbness and pain, weakness, tinnitus, visual disturbances, and dysphagia or dysarthria from cranial nerve palsies.5 A flexion teardrop fracture is a fracture- dislocation and one of the most unstable types of cervical spine fractures.
