Definition
Pott’s disease is a presentation of extrapulmonarytuberculosis that affects the spine, a kind of tuberculous arthritis of the intervertebral joints. It is named after
Percivall Pott (1714-1788), a London surgeon who trained at Barts. Scientifically, it is called tuberculousspond ylitis and it is most commonly localized in the thoracic portion of the spine.
AKA: Pott's syndrome, Pott's caries, Pott's curvature, angular kyphosis, kyphosis secondary to tuberculosis, tuberculosis of the spine, tuberculous spondylitis and David's disease Anatomy: The vertebral column provides structural support for the trunk and surrounds and protects the spinal cord. The vertebral column also provides attachment points for the muscles of the back and ribs. The vertebral disks serve as shock absorbers during activities such as walking, running, and jumping. They also allow the spine to flex and extend.
Pathophysiology:
Pulmonary tuberculosis | | Spread of mycobacterium tuberculosis from other | | Extrapulmonary Tuberculosis | | The infection spreads from two adjacent vertebraeinto the adjoining disc space | | Back pain, Fever, Night sweats, Anorexia, Weight loss, and easy | | One vertebra is affected, the disc is normalTwo are involved; the avascular intervertebral disc cannotreceive nutrients and collapse | | Disk tissue dies and broken down by | | Vertebral narrowing | | Vertebral collapse | | Spinal damage | | POTT’S DISEASE | | Kyphosis,paraplegia, bowel and urinary incontinenece | | Surgery: evacuation of pus, Anteriordecompression spinal fusion |
Signs and symptoms:
The earliest and most common symptom of Potts disease is back pain. As the disease progresses, fever, night sweats, lack of appetite and weight loss occur. The person may experience tingling, numbness and weakness in the legs.
Diagnostic & Laboratory: Blood Test: elevated erythrocyte sedimentation
