We undertook this study to evaluate chracteristics of hallux valgus in rheumatoid arthritis.

137 patients with rheumatoid arthritis were evaluated with clinical examination and radiological study for hallux valgue. 86 patients with degenerative joint disease were evaluated for control study.

Results
were as follows:

1) There were significant increase of hallux valgus angle as increase age, duration of disease, calcaneal valgus, grade of pes planus and 1st intermetatarsal angle (p<0.05).

2) There were significant correlation between hallux valgus angle between physical examination and radiological study (p<0.05).

3) There were no significant difference in hallux valgus angle between physical examination and radiological study (p≥0.05).

4) Hallux valgus was more frequent in degenerative joint disease than rheumatoid arthritis significantly (p<0.05).

This study suggested that hallux valgus tends to increase severity and frequency as aging, duration of joint disease, calcaneal valgus, grade of pes planus and 1st intermetatarsal angle, throughout long time. Rheumatoid arthritis is not unique disease to have hallux valgus.
