With the rapid development of industry in China, work injuries have increased in large numbers, and many patients with finger defects caused by machine injuries have appeared. Because there is no breakthrough in basic medical technology, it is still difficult to carry out allogeneic hand (finger) transplantation and autologous tissue engineering to construct hand (finger) transplantation in the clinic. The only treatment for finger defects is still autologous tissue transplantation and regenerative extension of the residual finger. At present, the most commonly used method is still toe transplantation to reconstruct the finger, but there are also some regeneration using residual finger osteotomy, there are also the use of other secondary function finger transplantation to reconstruct the important function finger, as well as the use of flap and bone grafting to extend the finger. Although toe transplantation is still the most commonly used and practical way to reconstruct fingers, however, there are many patients with finger defects who refuse to perform toe transplantation for the following reasons: (1) reconstructed fingers like toes are not very beautiful, especially the second toe transplantation of reconstructed fingers; (2) toe removal affects the future of walking and sports, especially farmers are most worried about this; (3) toe Defects affect the aesthetics of the foot; (4) the function of the reconstructed fingers; (5) toes shorter than the fingers, long finger defects how to do (6) the cost of the problem. With the continuous innovation of finger reconstruction technology, especially the emergence of finger full-type reconstruction, the above major problems plagued by patients and medical personnel have been solved. Finger reconstruction mainly utilizes part of the big toe’s nail and the toe’s abdomen to make the nail and the abdomen of the reconstructed finger have a realistic appearance. For phalangeal defects, the distal phalanx of the big toe can be chiseled and the dorsal 1/4 of the phalanx can be removed; for joint defects, the proximal interphalangeal joint of the second toe can be transplanted with a vascularized nerve; and for other bone defects, the iliopsoas strip is used for implantation and lengthening to maximize the preservation of all the toes. Skin defects of the toes can be repaired using implants and flaps. In the case of long finger defects, the finger can be lengthened by osteotomy, and then only part of the toenail and phalanx of the big toe can be removed to reconstruct the nail and phalanx of the finger, while in the case of joint defects, the proximal interphalangeal joint of the second toe can be transplanted by cutting out the vascularized nerves. In conclusion, with the improvement of the above reconstruction techniques, not only the shape of the reconstructed finger is perfect, but also the missing part of the toenail of the big toe can be removed later without sacrificing the toe. Because the surgery minimizes the removal and destruction of osteoarticular tissues and ligaments of the foot, the appearance of the foot, walking, and athletic function are minimally affected.
