Abstract
A surface replacement prosthesis for the first metatarsophalangeal joint has been designed to be used in arthritic conditions of this joint. The components are made of stainless steel and polyethylene and fixed with methylmethacrylate. The surgical details of insertion are important in such a complex, small joint. In the series of 20 patients (21 joints), the patient and physician satisfaction rate was 81% at an average follow-up period of 43 months (range 16 to 58 months). Current use of this prosthesis is most reasonable in older patients with painful degenerative arthritis of the first metatarsophalangeal joint and minimal joint imbalance.
