Tuberculous altantoaxial subluxation: a case report with review of literature.

Involvement of upper cervical and craniovertebral junction is rare but might lead to lethal consequences if the diagnosis is delayed. We present a case of atlantoaxial joint tuberculosis, resulting in gross instability of the joint. The patient was treated with antitubercular medication combined with posterior decompression and transarticular screw fixation. Patient improved neurologically, and clinical and radiological improvements were maintained at the latest follow-up of 2 years.
