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.

Wounds caused by physical agents, including physical trauma and chemical burns, can be treated with antibiotics and anti-inflammatory drugs to prevent bacterial infection and inflammation. Keeping the wound clean from infection also prevents necrosis.
A soft tissue injury is the damage of muscles, ligaments and tendons throughout the body. Common soft tissue injuries usually occur from a sprain, strain, a one-off blow resulting in a contusion or overuse of a particular part of the body.
Abrasions; Fluid that fills the new space can be a part of the clinical presentation. This can present as swelling that is soft with fluid that can be felt beneath the skin. [6] [7] [8] An acute clinical presentation will likely have bruising, swelling, and pain. [7] [8] The potential to accumulate fluids in the space has specific consequences.
An abrasion collar, also known as an abrasion ring or abrasion rim, is a narrow ring of stretched, abraded skin immediately surrounding projectile wounds, such as gunshot wounds. It is most commonly associated with entrance wounds and is a mechanical defect due to a projectile's penetration through the skin. It is caused by a temporary over ...
Debridement is an important part of the healing process for burns and other serious wounds; it is also used for treating some kinds of snake and spider bites. Sometimes the boundaries of the problem tissue may not be clearly defined.
Excoriation: A punctate or linear abrasion produced by mechanical means (often scratching), usually involving only the epidermis, but commonly reaching the papillary dermis. [30] [33] Ulcer: An ulcer is a discontinuity of the skin exhibiting complete loss of the epidermis and often portions of the dermis. [32] [33]
