An abrasion is a partial thickness wound caused by damage to the skin. [1] It can be superficial involving only the epidermis to deep, involving the deep dermis. Abrasions usually involve minimal bleeding. [ 2 ]
Erosion: An erosion is a discontinuity of the skin exhibiting incomplete loss of the epidermis, [32] a lesion that is moist, circumscribed, and usually depressed. [21] [33] Excoriation: A punctate or linear abrasion produced by mechanical means (often scratching), usually involving only the epidermis, but commonly reaching the papillary dermis ...
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. [3]
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. Soft tissue injuries can result in pain, swelling, bruising and loss of function. [1]
The ability of the skin to heal even after considerable damage has occurred is due to the presence of stem cells in the dermis and cells in the stratum basale of the epidermis, all of which can generate new tissue. When an injury extends through the epidermis into the dermis, bleeding occurs and the inflammatory response begins.
Excessive tensile strength can overstretch a muscle, causing a strain. Strains may present with torn muscle fibers, hemorrhaging, or fluid in the muscles. Severe muscle injuries in which a tear extends across the muscle can cause total loss of function. Penetrative trauma can cause laceration to muscles, which may take an extended time to heal.
Secondary intention is implemented when primary intention is not possible because of significant tissue damage or loss, usually due to the wound having been created by major trauma. [102] The wound is allowed to granulate. Surgeon may pack the wound with a gauze or use a drainage system. Granulation results in a broader scar.
Abrasion (dental), the loss of tooth structure by mechanical forces from a foreign element; Abrasion (medical), a wound consisting of superficial damage to the skin; Abrasion (mechanical), the process of scuffing, scratching, wearing down, marring, or rubbing away; Abrasion (geology), mechanical scraping of a surface by friction between moving ...
