Survival of the patient with traumatic occipito-atlantal dislocation is rare, only 3 reports of patients who recovered from this injury were found in a review of the literature (Corner 1970, Blackwood 1908, Farthing 1948, Wholey et al. 1958, Garbielsen and Maxwell 1966, Yajnik and Doshi 1977). Most injuries of this type are instantly fatal but autopsy information on the anatomical lesion is sparse. In these cases either the medulla oblongata or the spinomedullary junction may be served. The occipito-atlanto-axial ligaments are strong, and fracture usually precedes ligamentous rupture. Spontaneous non-traumatic occipito-atlantal dislocations have been reported secondary to inflammatory diseases that include rheumatoid arthritis, ankylosing spondylitis, and acute tonsillitis and in these the atlantoid joints and synovial tissue are affected by the inflammation, and periariticular bone is resorbed causing occipito-atlantal instability. Here too, if the instability is severe, dislocation and death may occur. A case of traumatic occipito-atlantal subluxation is presented here.
