Hallux metatarsophalangeal arthroplasty in the rheumatoid forefoot.

Surgical options for treatment of the hallux valgus deformity in the rheumatoid forefoot are numerous, but long-term results of many of these procedures have been less than satisfactory. Controversy exists as to whether excision or fusion is preferred for the treatment of the hallux metatarsophalangeal (MTP) joint. The role of replacement arthroplasty needs to be evaluated. The available surgical options for treatment of the arthritic first MTP joint in rheumatoid arthritis include arthrodesis, excision of the metatarsal head with or without interposition of the soft tissues, excision of the proximal phalanx, and silicone hinge replacement. This article discusses the various types of arthroplasty of the first MTP joint and the reported outcomes in the rheumatoid forefoot.
