Cervical dysplasia is a general term for a group of cervical spine disorders, including atlantoaxial dislocation, atlantoaxial subluxation and cervical subluxation, which in severe cases can lead to tetraplegia and even death from respiratory failure.
Because of its high rate of disability and death, it must be diagnosed and managed promptly. Atlantoaxial screw fixation needs to be considered in cases where the quality of life is seriously affected.
