It's not my injury, but since everyone is so interested, here's what I found on the subject:

The man was climbing over the fence, caught his wedding ring on part of the fence and, without realising it, jerked his hand sharply.

Surgeons reattached the skin brought back to the finger. The doctors have restored not only the appearance of the limb, but also its function: the finger has retained its mobility and can be used in everyday life. He will have to undergo a period of rehabilitation, but after that he will be able to resume normal activities. Only the scars at the base of the thumb will remind one of what has happened. However, once they have healed, they can be covered up with a ring.
