Tuberculous arthritis

Definition:

An inflammation of the joints resulting from tuberculosis infection. (See also spondylitis).

Causes, incidence, and risk factors:

Approximately 1% of people affected with tuberculosis will develop arthritis. The joints most frequently involved are the spine, hips, knees, wrists, and ankles. The hunchback of Notre Dame had a gibbous deformity (humpback) which was thought to be due to tuberculosis, a common cause of gibbous deformity.

The arthritis can be very destructive and lead to the collapse of the vertebrae. Muscle atrophy and muscle spasms can occur.
