RESUMO
Objective To summarize the clinical experience in the replacement of the damaged sec- ond metacarpophalangeal joint with the second metatarsophalangeal joint with a pedicle of dorsal pedis artery and great saphcnous vein.Methods The damaged second metacarpophalangeal joint,distal part of the sec- ond metacarpal and proximal part of the proximal phalanx were dissected.The metatarsophalangeal joint was transferred to the region of metacarpophalangeal joint of hand.The dorsal pedis artery was anastomosed to the radial artery,and the great saphenous vein was anastomosed to the cephalic vein at anatomical snuff-box.The dissected bones of the hand removed of the cartilage of joint and soft tissue were grafted back to the donor site of the foot.Results A 5～30 month follow-up study in 8 out of 11 cases showed that satisfactory functional recovery was achieved in clinical practice.The movement of second metacarpophalangeal joint was excellent. Conclusion The function of the second metacarpophalangeal joint can be effectively recovered by the trans- fer of the vascularized second metatarsophalangeal joint.
