Lacerations – irregular tear-like wounds caused by some blunt trauma. Lacerations and incisions may appear linear (regular) or stellate (irregular). The term laceration is commonly misused in reference to incisions. [9] Abrasions (grazes) – superficial wounds in which the topmost layer of the skin (the epidermis) is scraped off.
Wound healing refers to a living organism's replacement of destroyed or damaged tissue by newly produced tissue. [1] In undamaged skin, the epidermis (surface, epithelial layer) and dermis (deeper, connective layer) form a protective barrier against the external environment. When the barrier is broken, a regulated sequence of biochemical events ...
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.
Most injuries to the skin are minor and do not require specialist treatment. Lacerations of the skin are typically repaired with sutures, staples, or adhesives. The skin is susceptible to burns, and burns to the skin often cause blistering. Abrasive trauma scrapes or rubs off the skin, and severe abrasions require skin grafting to repair. Skin ...
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 bone).
In a major injury, if epithelial cell migration and tissue contraction cannot cover the wound, suturing the edges of the injured skin together, or even replacement of lost skin with skin grafts, may be required to restore the skin. As epithelial cells continue to migrate around the scab, the dermis is repaired by the activity of stem cells.
The RICE method is an effective procedure used in the initial treatment of a soft tissue injury. [6] Rest It is suggested that the patient take a break from the activity that caused the injury in order to give the injury time to heal. Ice The injury should be iced on and off in 20 minute intervals, avoiding direct contact of the ice with the skin.
A perineal tear is a laceration of the skin and other soft tissue structures which, in women, separate the vagina from the anus. Perineal tears mainly occur in women as a result of vaginal childbirth , which strains the perineum .
