Arthrodesis of the first metatarsophalangeal joint for hallux valgus in rheumatoid arthritis.

We reviewed the results of reconstruction of the fore part of the foot in rheumatoid patients by arthrodesis of the first metatarsophalangeal joint. The follow-up averaged 4.1 years (range, 2.0 to 7.25 years). Eighteen feet in eleven women were operated on. Twelve feet underwent total reconstruction of the fore part: arthrodesis of the first metatarsophalangeal joint and excision of all of the lesser metatarsophalangeal joints. Six feet underwent subtotal reconstruction, which included arthrodesis of the first metatarsophalangeal joint. The results were classified as excellent in fourteen feet, good in two, and fair in two. There were no poor results. Metatarsophalangeal bone fusion was achieved in all but one foot (fusion rate, 94 per cent). The one fibrous ankylosis was painless, with satisfactory function. Interphalangeal degenerative joint disease was a radiographic but not a clinical sequela. Arthrodesis of the first metatarsophalangeal joint provided stability that permanently corrected deformity, permitted the patients to wear ordinary shoes, and, in combination with excisional arthroplasty of involved lesser metatarsophalangeal joints, relieved disabling pain in the fore part of the foot.
