Postoperative pressure under the rheumatic feet.

The authors examined ten seropositive rheumatoid arthritis patients with an EMED gait analysis system in a mean four years after foot surgery and compared that with ten normal subjects who formed a control group. The maximum pressure in the toe regions was almost the same as in the control group. The rheumatoid arthritis group had significantly increased maximum pressure in the first metatarsal and tarsal region.
