M03.1: Postinfective arthropathy in syphilis

Postinfective arthropathy in syphilis is a condition that represents joint inflammation, commonly known as arthritis, occurring as a result of a syphilis infection. Syphilis is a sexually transmitted disease caused by the bacterium Treponema pallidum. In the case of postinfective arthropathy, the bacteria may spread to the joints triggering the body's immune response, resulting in inflammation and joint pain. Symptoms can include joint swelling, redness, warmth, and difficulty in movement, often following a similar pattern as other types of arthritis. The affected joints can be varied but are frequently those most used like the knees or wrists. The progression and severity of the condition can depend on the individual and the stage of the syphilis infection.
