Patient sustained a ring avulsion injury to his middle finger.
Avulsion is an injury in which a body structure is forcibly detached from its normal point of insertion by either trauma or surgery. The term most commonly refers to a surface trauma where all layers of the skin have been torn away, exposing the underlying structures. Damage from the abrupt and often harsh tug of the caught ring can range from a simple bruise to “degloving” of soft tissue – pulling the skin off and stripping away the nerves, tendons and bone. Severe accidents may result in traumatic amputation of the finger.Ring avulsion can be among one of the most devastating traumatic finger injuries, as often replantation following severe soft tissue damage is not possible.Fortunately, advances in microsurgery have improved results with ring avulsion replantation.
