In medicine, an avulsion is an injury in which a body structure is torn off by either trauma or surgery (from the Latin avellere, meaning "to tear off"). [1] The term most commonly refers to a surface trauma where all layers of the skin have been torn away, exposing the underlying structures (i.e., subcutaneous tissue , muscle , tendons , or ...
A degloving injury is a type of soft-tissue avulsion injury that can occur anywhere in the body. [1] Commonly affected areas include the face, scalp, trunk, limbs, and genitalia. [1] Degloving injuries are caused by shearing forces that cause the soft tissue layers to get pulled apart.
Abrasions on elbow and lower arm. The elbow wound will produce a permanent scar. A first-degree abrasion involves only epidermal injury. A second-degree abrasion involves the epidermis as well as the dermis and may bleed slightly. A third-degree abrasion involves damage to the subcutaneous layer and the skin and is often called an avulsion.
A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease.

Degloving and avulsion injuries involve the removal of the penis skin, which is a serious medical emergency. Treatment of these injuries involves either closure of the torn skin, or a skin graft to replace the skin lost in the injury. Skin grafts are constructed to attempt to preserve erectile function and sensation. [1]
An avulsion fracture is a bone fracture which occurs when a fragment of bone tears away from the main mass of bone as a result of physical trauma. This can occur at the ligament by the application of forces external to the body (such as a fall or pull) or at the tendon by a muscular contraction that is stronger than the forces holding the bone ...

Traumatic amputation is the partial or total avulsion of a part of a body during a serious accident, like traffic, labor, or combat. [ 57 ] [ 58 ] Traumatic amputation of a human limb, either partial or total, creates the immediate danger of death from blood loss.
