Complex regional pain syndrome (CRPS) complicated with septic arthritis of the hand has not previously been described. We treated a patient in whom swelling of the wrist recurred during treatment of CRPS and septic arthritis of the hand was induced by group G hemolytic streptococcus. There are case reports of tuberculous arthritis of the hand during treatment of CRPS;however, the causal relationship of wrist joint inflammation with CRPS is unclear. Careful follow-up is necessary for wrist joint inflammation if a patient with CRPS relapses with swelling of the wrist.
