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.

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.
The type of wound (incision, laceration, puncture, etc.) has a major effect on the way a wound is managed, as does the area of the body affected and presence of any foreign objects in the wound. A serious wound or any complication may require a call to emergency medical services. Any wound requires being disinfected after it stops bleeding.
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]
Abrasions are superficial injuries to the skin no deeper than the epidermis tissue layer, and bleeding, if present, is minimal. Minor abrasions generally do not scar, but deeper abrasions generally bleed and may scar. Blunt trauma causes sports-related lacerations, resulting in burst-type open wounds with jagged irregular edges.
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.
Chronic ulcer symptoms usually include increasing pain, friable granulation tissue, foul odour, and wound breakdown instead of healing. [3] Symptoms tend to worsen once the wound has become infected. Venous skin ulcers that may appear on the lower leg, above the calf or on the lower ankle usually cause achy and swollen legs.
