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 ...
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 ...
If conservative treatment of a minor ingrown toenail does not succeed or if the ingrown toenail is severe, surgical management by a podiatrist is recommended. [1] The initial surgical approach is typically a partial avulsion of the nail plate known as a wedge resection or a complete removal of the toenail. [1]
A more traumatic abrasion that removes all layers of skin is called an avulsion. Abrasion injuries most commonly occur when exposed skin comes into moving contact with a rough surface, causing a grinding or rubbing away of the upper layers of the epidermis.
Dental avulsion is a type of dental trauma, and the prevalence of dental trauma is estimated at 17.5% and varies with geographical area. [36] Although dental trauma is relatively low, dental avulsion is the fourth most prevalent type of dental trauma. [37] Dental avulsion is more prevalent in males than females.
Avulsions are difficult to repair, and no avulsion should ever be considered a minor injury. Amputation: Similar to, but distinct from, an avulsion. Whereas an avulsion is characterized by a "flap" of skin being removed, an amputation is characterized by a complete loss of a limb. This can occur at any point on the extremity, and is usually ...
The treatment of a degloving injury requires assessment of the damage to the soft tissue and associated blood vessels. [1] Any soft tissue that is dead must be removed. [ 1 ] [ 2 ] If the soft tissue that was torn away is healthy and has a blood supply, it can be used in the treatment. [ 1 ]
Treatment will depend on whether the tooth has an open or closed apex and how long the tooth has been out of the mouth prior to dental clinic arrival (see Dental Trauma Guide for full treatment details) 4 weeks: splint removal, clinical and radiographic examination 3 months: clinical and radiographic examination
