Six cases of autotransplantation of free vascularized second metatarsophalangeal joint to reconstruct damaged metacarpophalangeal (MP) joints are reported. Anatomical studies in cadaver and clinical cases involving the origin, course, and importance of preserving the articular branch of the metatarsal artery are described. Follow-up of cases from six months to 21/2 years postoperative reveal recovery of thumb function, stability of the transplanted joint, and no obvious degenerative changes.
