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.

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.
Deep wound on shin with stitches healing over five weeks. The wound-healing process is not only complex but fragile, and it is susceptible to interruption or failure leading to the formation of non-healing chronic wounds. Factors that contribute to non-healing chronic wounds are diabetes, venous or arterial disease, infection, and metabolic ...
Penetrating trauma is an open wound injury that occurs when an object pierces the skin and enters a tissue of the body, creating a deep but relatively narrow entry wound.In contrast, a blunt or non-penetrating trauma may have some deep damage, but the overlying skin is not necessarily broken and the wound is still closed to the outside environment.
the nature of the wound, whether it is a laceration, abrasion, bruise or burn the size of the wound in length, width and depth the extent of the overall area of tissue damage caused by the impact of a mechanical force, or the reaction to chemical agents in, for example, fires or exposure to caustic substances.
Normally the subcutaneous tissue layer is attached to the fibrous layer that covers muscles known as deep fascia. [1] 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]

Abdominal CT showing left renal artery injury. Blunt abdominal trauma (BAT) represents 75% of all blunt trauma and is the most common example of this injury. [3] Seventy-five percent of BAT occurs in motor vehicle crashes, [4] in which rapid deceleration may propel the driver into the steering wheel, dashboard, or seatbelt, [5] causing contusions in less serious cases, or rupture of internal ...
