According to what you said, it is already rotten and the severed finger is gone. It should be that the hair has not been replanted.

Reconstructive surgery is possible.

Replantation:

Generally, it refers to the re-anastomosis of bones, blood vessels, nerves, tendons, and skin of a completely or incompletely severed finger within 8 hours. Reconstruction refers to an operation to restore part of the original function.

As for prosthetics, silicone finger prostheses are most commonly used at present. They have a similar appearance, but have no feeling or function and are low in cost.

Prosthetic fingers cost several hundred to several thousand. You need to consult the local prosthetic factory. Prosthetic fingers have no function, only appearance, and need to be replaced regularly;

Full-shaped reconstructed fingers , are real fingers, with appearance, function and feeling. After rehabilitation exercises, most functions can be restored, such as pinching and grasping, etc.

Reconstruction:

To put it simply, it is through Surgically reconstruct a normal finger. Finger reconstruction has gone through flap reconstruction, toe transplantation, and currently total reconstruction. The difference is that skin flap reconstruction has no function and simply wraps the injured finger; toe transplantation is to take a toe from the foot and transplant it to the injured hand;

Full-shape reconstruction It is a new technology developed on the basis of toe transplantation. Before transplantation, the shape (bone, nail flap) is modified to make it nearly consistent with the appearance of a normal finger, and the shape of the phalanges is the same. At the same time, blood vessels and blood vessels are anastomosed under a microscope. Nerves, tendons, and Kirschner wires fix the bone connection parts. After post-rehabilitation exercises, the reconstructed fingers can have normal grip, feeling, and perception.

Because the difficulty of full-shape finger reconstruction is very different from that of ordinary toe transplantation, reconstruction is different from other surgeries. The difference is a thousand miles. The entire operation is performed under a microscope, so the operation time is generally more than ten hours. Master this There are fewer hospitals and experts with similar skills, and one suture error will lead to the failure of the entire operation.
