Arthrodesis procedures for salvage of the hallux metatarsophalangeal joint.

First metatarsophalangeal (MTP) fusion has been recommended as a means to salvage various great toe deformities. These deformities include failed hallux valgus procedures, failed silicon implants, previous infection, rheumatoid arthritis, post-traumatic conditions, hallux rigidus, severe hallux valgus deformities, and neuromuscular disorders. A variety of complications, such as hallux varus, first MTP joint instability, infection, recurrent hallux valgus, and avascular necrosis of the first metatarsal head can develop from hallux valgus deformity treatment procedures.
