Which of the following is incorrect regarding spinal tuberculosis?
ExplanationSpinal tuberculosis (TB) originates in the metaphysis of the vertebral body and spreads under the anterior longitudinal ligament causing destruction of several contiguous levels and skip lesions in 15% of the cases. The disc spaces are preserved in the early stages of the infection, which differentiates TB of the spine from pyogenic infection. Contrary to a spinal cord injury occurring as a result of meningomyelitis, a cord injury secondary to direct pressure from the TB abscess or the bony sequestra carries a good prognosis.
