Classification

Spinal Tuberculosis has no classification but the paraplegia as a result of the infection can be classified into early and late paraplegia based on the activity of the tuberculous infection:

Early Paraplegia

• It develops in the active stage of tuberculosis infection, commonly seen in adults with Pott's spine.
• The spinal compression is due to the pressure from the necrotic debris from the damaged bone and intervertebral disc, pus and the granulation tissue.
• Spinal compression in spinal tuberculosis can result from other causes causing compression such as subluxation and dislocation due to destruction of anterior column, compression fracture as a result of wide spread infection, spread of infection to the spinal cord, arterial thrombosis and formation of a intra or extramedullary tuberculoma of the spinal cord.

Late Paraplegia

• It is a complication that develops in a patient with healed tuberculosis. The timing of presentation is variable and can occur 2 or 3 decades after the active infection.
