Reconstruction of Metacarpophalangeal Joint by Free Vascularized Autogenous Metatarsophalangeal Joint Transplant
The metacarpophalangeal (MP) joint is essential to hand function, which will suffer severe deterioration in the event of traumatic or arthritic stiffening. Early this century, a stiffened MP joint was replaced by autograft of a small joint which was subjected to degenerative changes within 1–2 years. Since Buncke’sl second to third MP joint transplantation on an intact vascular pedicle was proved to be successful without any late degenerative changes in long term observation in 1967, experimental small joint transplantation was undertaken independently by Bunckel and Hurwitz2, with the same conclusion: long term survival of the vascular graft without any degeneration and severe degenerative alteration in nonvascular transplant.
