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 ...
A degloving injury is a type of soft-tissue avulsion injury that can occur anywhere in the body. [1] Commonly affected areas include the face, scalp, trunk, limbs, and genitalia. [1] Degloving injuries are caused by shearing forces that cause the soft tissue layers to get pulled apart.
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 ...
This is known as a permanent or full nail avulsion, or full matrixectomy, phenolisation, or full phenol avulsion. As can be seen in the images below, the nail-less toe does not look like a normal toe. Fake nails or nail varnish can still be applied to the area to provide a normal appearance. In a few cases phenolisation is not successful and ...

Degloving and avulsion injuries involve the removal of the penis skin, which is a serious medical emergency. Treatment of these injuries involves either closure of the torn skin, or a skin graft to replace the skin lost in the injury. Skin grafts are constructed to attempt to preserve erectile function and sensation. [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.
Originally described by Dr. Paul Segond in 1879 [6] [7] after a series of cadaveric experiments, the Segond fracture occurs in association with tears of the anterior cruciate ligament (ACL) (75–100%) and injury to the medial meniscus (66–75%), lateral capsular ligament (now known as the Anterolateral ligament, or ALL), as well as injury to the structures behind the knee.
