Rheumatoid arthritis affects the foot very frequently. The transversal arch of the foot gradually declines due to the inflammation, the metatarsal heads protrude in the sole of the foot which is accompanied by painful bunions and sometimes also skin necrosis. The great toe turns into a valgus position and pronation. Walking is very painful.
The authors evaluate a group of patients operated on for the deformities of the forefoot between 1995 and 2002.
In the deformities of the forefoot the authors use resection of the heads of II-V metatarsals. They use a plantar surgical approach during which they remove bunions under the heads of the metatarsals. Then they gradually perform resection of the heads of--V metatarsals. In case of the great toe they prefer resection after Keller. In 5 cases they used fusion of the MTP joint of the great toe. They use fusion only in cases of a marked valgus position of the great toe. Where I MTT was in a significantly varus position, they applied in 3 cases the Lapidus procedure.
Between 1995 and 2002 they operated on 92 patients, in 38 of them the surgery was performed bilaterally. Evaluation covered 130 surgeries. In 85 cases the patients had rheumatoid arthritis, in 7 the basic diagnosis was psoriatic arthritis. The group included 72 women and 20 men. The average age at the time of surgery was 38.4 years. Eighty-two (63.1%) patients were without pain 7 (5.4%) patients had severe pain. The authors monitored the occurrence of revalgization of the great toe after Keller resection arthroplasty--of 77 patients revalgization occurred in 23 cases (29.8%). The complications included 3 times a late infect 1-2 years after the surgery after the protrated infect of the organs, 3 times a skin necrosis between the great toe and 2nd metatarsal, when prior to the surgery there was a significant valgus deformity and after the correction of the great toe there was a skin tension in this region, 6 times a delayed healing of the wound on the sole of the foot.
The authors present different surgical techniques of the forefoot and the great toe of the foot used by different authors.
As the patients suffer from a polyarticular affection the emphasis is put on the individual approach and a properly timed operation. In this respect of vital importance is the cooperation involving a rheumatologist, orthopaedic surgeon, physical therapist and prosthetic department. Orthopaedic insoles and orthopaedic shoes are an integral part of the comprehensive therapy. Surgical treatment is not very demanding for patients and in most cases it brings a significant relief.
