Rheumatoid arthritis that involves the hindfoot is disabling because it affects the patient's ability to walk. Fifteen patients with ankle pain who demonstrated isolated hindfoot arthritis clinically and radiographically underwent 19 selective hindfoot arthrodeses. At followup averaging 3 ½ years, results were rated good in 16, fair in four, and none were rated poor. Selective hindfoot fusion is effective in relieving pain and restoring the foot to ambulatory status.
