The Swanson flexible hinge toe implant is a double-stemmed flexible hinge implant designed to restore function to the metatarsophalangeal joints disabled by rheumatoid, degenerative, or post traumatic arthritis. In the first metatarsophalangeal joint, the implant is used in cases of moderate to severe hallux valgus deformity secondary to rheumatoid arthritis, or to senile degenerative arthritis and in cases of bony destruction on both sides of the joint. In the lateral metatarsophalangeal joints, the implant is used in cases of dislocation and extension contracture of the metatarsophalangeal joint, in cases of bone destruction of one or both joint surfaces as in rheumatoid arthritis and in cases of dislocation resulting from resection of the base of one or both joint surfaces as in rheumatoid arthritis.
