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.
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.
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Blunt trauma can lead to a wide range of injuries including contusions, concussions, abrasions, lacerations, internal or external hemorrhages, and bone fractures. [1] The severity of these injuries depends on factors such as the force of the impact, the area of the body affected, and the underlying comorbidities of the affected individual.
Tears are classified into four categories: [4] [5] First-degree tear: laceration is limited to the fourchette and superficial perineal skin or vaginal mucosa; Second-degree tear: laceration extends beyond fourchette, perineal skin and vaginal mucosa to perineal muscles and fascia, but not the anal sphincter
A hippopotamus with an avulsion injury to its face. 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 wound was so deep that bones in Garcia’s back were exposed, the lawsuit read. Doctors treated her with IV antibiotics and cleaned the wound. However, she died on July 2.
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.
