Simply put, it is to reconstruct a normal finger through surgery. Finger reconstruction has gone through skin flap reconstruction, toe transplantation and now total reconstruction. The difference is that flap reconstruction has no function, but simply wraps the injured finger; Toe transplantation is to take a toe from the foot and connect it to the injured hand through transplantation;

Total reconstruction is a new technology developed on the basis of toe transplantation Before transplantation, it was modified (bone and toenail flap) to make it close to the appearance of normal fingers and the shape of phalanges was consistent. At the same time, the blood vessels, nerves and tendons were anastomosed under the microscope, and the joints were fixed with Kirschner wires. After later rehabilitation exercise, the reconstructed fingers can have normal grip strength, feeling and perception.

Because the difficulty of full-length finger reconstruction is very different from that of ordinary toe transplantation, and the reconstruction is also different from other operations, the whole operation is carried out under a microscope, so the operation time is generally more than ten hours, and few hospitals and experts have mastered this technology. One suture error will lead to the failure of the whole operation.
