Metacarpophalangeal Joint Reconstruction by Vascularized Partial Metatarsophalangeal Joint Transplantation

Abstract

Case: A 27-year-old man underwent metacarpophalangeal joint reconstruction of his right middle finger using vascularized tissue from the distal component of the metatarsophalangeal joint of the right second toe. The donor site was reconstructed using a portion of the iliac bone and overlying tendinous fiber. The reconstructed metacarpophalangeal joint was stable 2 years postoperatively, and the arc of active motion was 80°. The reconstructed metatarsophalangeal joint did not interfere with walking. Radiography revealed the satisfactory condition of these joints. Conclusion: Depending on the type of defective joint and soft tissue injuries, vascularized partial joint transplantation could be considered for reconstruction.
