Rheumatology

CHARCOT JOINTS

1. Commonly occurs in daibetics.

2. Joint findings are similar to severe OA, with osteophytes, except that erosions also can occur.

3. Commonly affects the MTPJ, tarsal and talar joints.

4. Pathology - repeated trauma secondary to loss of pain sensation and/or proprioception; autonomic dysfunction that leads to regional hyperemia, osteoclastic stimulation, and active bone resorption.

5. To try to repair the damage, bone becomes overgrown, known as periositis, and non-inflammatory joint effusions develop.

6. Eventually, the joints become unstable and lax.
