Avulsion Injuries
Avulsion in general refers to a tearing away. Specifically, it can refer to: * Avulsion fracture, when a fragment of bone tears away from the main mass of bone as a result of physical trauma * Avulsion injury, in which a body structure is detached from its normal point of insertion, either torn away by trauma or cut by surgery * Avulsion (legal term), the sudden loss of land by the action of water * Avulsion (river), abandonment of an old river channel and the formation of a new one {{disambiguation ...

Avulsion Fracture
An avulsion fracture is a bone fracture which occurs when a fragment of bone tears away from the main mass of bone as a result of physical trauma. This can occur at the ligament by the application of forces external to the body (such as a fall or pull) or at the tendon by a muscular contraction that is stronger than the forces holding the bone together. Generally muscular avulsion is prevented by the neurological limitations placed on muscle contractions. Highly trained Athlete, athletes can overcome this neurological inhibition of strength and produce a much greater force output capable of breaking or avulsing a bone.

Avulsion Injury
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"). 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). This is similar to an abrasion but more severe, as body parts such as an eyelid or an ear can be partially or fully detached from the body. Skin avulsions The most common avulsion injury, skin avulsion, often occurs during motor vehicle collisions. The severity of avulsion ranges from skin flaps (minor) to degloving (moderate) and amputation of a finger or limb (severe). Suprafascial avulsions are those in which the depth of the removed skin reaches the subcutaneous tissue layer, while subfascial avulsions extend deeper than the subcutaneous layer.Jeng, S.F., & Wei, F.C.

Avulsion (legal Term)
In real property law, avulsion refers to a sudden loss of land, which results from the action of water. It differs from accretion, which describes a gradual addition to land resulting from the action of water. Avulsion and riparian owners The distinction between avulsion and accretion becomes important if a river forms the boundary between two riparian owners. In many jurisdictions, if the river changes channels by avulsion, the boundary does not change but remains in the middle of the old channel. For example, the Mississippi River forms the boundary between several U.S. states, and the principle causes states on the lower Mississippi to have occasional pieces of land on the opposite side from the rest of the state. The river changed course quickly in such locations and so the boundaries did not change.) However, as a river gradually changes through accretion, the boundary changes with it. To prove that a change was avulsion and not accretion, it is sufficient, at least under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
