Overview

Pott's disease may be complicated by severe vertebral deformity and collapse resulting in kyphosis, cord compression, sinus formation, and paraplegia. However, it responds well to treatment, if it is not complicated by severe deformity or established neurologic deficit.

Complications

The destruction of the intervertebral disc, body of the vertebra and spread of the infection can result the following complications:

• Vertebral collapse resulting in kyphosis
• Spinal cord compression
• Paraplegia (so called Pott's paraplegia)
• Formation of a cold abscess
• Infection can spread down the sheath of the psoas muscle to the femoral trigone to form a sinus .

Prognosis

Pott's disease responds well to treatment, if it is not complicated by severe deformity or established neurologic deficit.
