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.

Injuries from blunt trauma may cause internal bleeding and bruising from ruptured capillaries beneath the skin, abrasion from scraping against the superficial epidermis, lacerated tears on the skin or internal organs, or bone fractures. Crush injuries are a severe form of blunt trauma damage that apply large force to a large area over a longer ...
First-degree nerve injury requires a few hours to a few weeks to recover. [62] If a foreign body passes by a nerve and causes first-degree nerve injury during entry, then the sensation of the foreign body or pain due to internal wounding may be delayed by a few hours to a few weeks after entry.
Bone pain originates from both the periosteum and the bone marrow which relay nociceptive signals to the brain creating the sensation of pain. Bone tissue is innervated by both myelinated (A beta and A delta fiber) and unmyelinated sensory neurons. In combination, they can provide an initial burst of pain, initiated by the faster myelinated ...
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]
Wrist mobility is often restricted due to inflammation of the forearm muscles as they contract and tighten due to injury. [2] Most wrist dislocations occur between the capitate and the lunate . [ 17 ] [ 18 ] Carpal fractures are caused by falling on an outstretched hand the wrist is hyper-extended in ulnar deviation with a component of rotation ...
Fr. C 1 - Superficial contusion or abrasion to the skin II Fr. O 2 - Skin laceration with circumferential skin or soft-tissue contusion and moderate contamination Fr. C 2 - Deep contaminated abrasions with skin or muscle contusion from direct trauma III Fr. O 3 - Extensive soft-tissue damage with major vessel or nerve injury
