ABSTRACT
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 2œ years postoperative reveal recovery of thumb function, stability
of the transplanted joint, and no obvious degenerative changes.
