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
A superficial gunshot wound to the armpit. As a missile passes through tissue, it decelerates, dissipating and transferring kinetic energy to the tissues. [1] The velocity of the projectile is a more important factor than its mass in determining how much damage is done; [1] kinetic energy increases with the square of the velocity.
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
The dingo bit the four-year-old child on the left shoulder, resulting in “superficial lacerations” before being chased away by the child's father. In a third attack on toddlers, a three-year ...
The wounded officer sustained superficial lacerations to his head and arm which had to be glued following medical attention. In a victim impact statement he described how the attack left him ...
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.
It is useful for deep lacerations, where it can replace two layers of deep and superficial sutures. It can help bring the deep layers together alone, allowing several simple interrupted or running stitches to close the remaining superficial skin. Vertical mattress sutures are not recommended for sites such as the palm of the hand, where ...
Spleen is the most common cause of massive bleeding in blunt abdominal trauma to a solid organ. Spleen is the most commonly injured organ. A laceration of the spleen may be associated with hematoma. [13] Because of the spleen's ability to bleed profusely, a ruptured spleen can be life-threatening, resulting in shock.
