Early decompression in Pott's paraplegia gives encouraging results. It produces speedy recovery from paraplegia and ensures rapid healing of the lesion. Lateral extrapleural decompression without fusion for lesions of thoracic vertebrae is safe and satisfactory. It gives adequate exposure of the anterior and posterior parts of the vertebral bodies and of the theca, without endangering the stability of the spine. Age, sex and site of the lesion have no influence on the prognosis, whereas paraplegia of longer duration, paraplegia in flexion, and paraplegia presenting as a spinal cord tumour carry a bad prognosis. In early lesions there is reconstitution of vertebral bodies whereas in advanced lesions there is consolidation or bony fusion.
