Salvage of failed proximal interphalangeal arthroplasty with vascularised toe joint transfer: Report of two cases.

Failed implants of the proximal interphalangeal joint may result in bone and soft tissue deficits and joint instability with limited reliable options for reconstruction besides an arthrodesis procedure. The purpose of this report is to illustrate the use of vascularized second toe joint for salvage of failed, multi-operated proximal interphalangeal joint in two active patients. Pre-existing scars are used to define the approach and choice of donor site. Flow through anastomosis was performed on the finger digital artery. At final follow-up, the transplanted joints achieved 80-90 degrees of motion and the patients were able to return to their desired level of activities. The procedure is a good alternative for the fit patient wanting to achieve a stable finger with preservation of motion in catastrophic failure of prosthetic proximal interphalangeal joint arthroplasty.
