Vascularized toe joint transfers to the hand for PIP or MCP reconstruction.

Vascularized toe joint transfers are used for proximal interphalangeal (PIP) or metacarpophalangeal reconstruction of the fingers in children or young adults, as an alternative to joint arthroplasty. In children, this reconstruction aims to restore range of motion (ROM) and the growing capacities. The typical donor sites are the PIP or metatarsophalangeal joints of the second toe. These transfers are performed with short vascular pedicles in order to simplify the surgical technique and reduce the overall morbidity. Local flaps and joint fusion are used to reconstruct the donor toe. Indications for these transfers are mainly compound defects due to trauma or infection. While these reconstructions provide a long-lasting result, the ROM achieved is always smaller than the normal ROM of the recipient joint.
