Elective free vascularized double transfer of toe joint from second toe to proximal interphalangeal joint of index finger: a case report.

Alternatives to the treatment of major injuries to the proximal interphalangeal (PIP) joint include fusion, implant arthroplasty, perichondrial grafting, single autogenous free vascularized transfer, and double autogenous free vascularized transfer. A patient presented a gunshot wound to the index finger with loss of skin and extensor tendon and PIP joint disruption. The finger was reconstructed with a composite free flap of skin and extensor tendon and PIP and distal interphalangeal joints of the second toe. A follow-up of 10 months is presented, which demonstrates PIP joint motion and finger function.
