First metatarsophalangeal joint arthroplasties in the Commonwealth of Virginia.

This retrospective analysis of arthroplasty of the first metatarsophalangeal joint documents the incidence of surgery as well as the selection of the commercially available implants. During a 1-year period, 1994, arthroplasties were performed in 47 of the 1.7 million subscribers to Trigon Blue Cross Blue Shield of Virginia. Women received the majority of the arthroplasties (83%). Of the 47 cases, the silicone implant was predominantly used (83%). The most common indications for arthroplasty were hallux valgus (30%) and hallux rigidus (28%). Podiatrists performed 79% of the procedures, while orthopedic surgeons performed the remaining 21% of the cases. A prospective study is needed that will assess the long-term performance of the different implants.
