Degloving finger injury!
This young man was lucky to have a ring on. He was cleaning dead leaves from the roof when suddenly his leg slipped over the edge. Miraculously, while falling, his finger got caught and was still hanging on the gutter by the ring, pulling the skin off his bone, but saving him from falling! He got rescued by the fireman shortly after. Degloving injury is a type of avulsion in which and extensive section of skin is completely torn off the underlying tissue, severing its blood supply. It's named by analogy to the procces of removing a glove. Typically, degloving injuries affect the extremities and limbs and they require major surgical intervention. Treatment options include replantation or revascularization of the degloved skins, or when these aren't possible, skin grafts or skin flaps.While the preservation of the extremities and limbs is normally preferred, in some severe cases amputations may be advised or required.
