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 ...
Gamekeeper's thumb and skier's thumb are two similar conditions, both of which involve insufficiency of the ulnar collateral ligament (UCL) of the thumb. The chief difference between these two conditions is that skier's thumb is generally considered to be an acute condition acquired after a fall or similar abduction injury to the metacarpophalangeal (MCP) joint of the thumb, whereas gamekeeper ...

[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 ...

Pipkin: posterior dislocation of hip with avulsion fracture of fragment of femoral head by the ligamentum teres: impact to the knee with the hip flexed (dashboard injury)
Medial Epicondyle Fracture of the Humerus. A medial epicondyle fracture is an avulsion injury to the medial epicondyle of the humerus; the prominence of bone on the inside of the elbow. Medial epicondyle fractures account for 10% elbow fractures in children. 25% of injuries are associated with a dislocation of the elbow.
The Segond fracture is a type of avulsion fracture (soft tissue structures pulling off fragments of their bony attachment) from the lateral tibial plateau of the knee, immediately below the articular surface of the tibia (see photo).
Matthew Stafford suffers a lateral ankle sprain in the Rams' victory over the Saints and the Rams add depth at cornerback with signing of former No. 1 pick.
The Maisonneuve fracture generally follows a specific pattern of injury. The following are described as subsequent events that result in a Maisonneuve fracture: [3] [4] [12] Forceful, external rotation of the ankle joint results in the tearing of the deep deltoid ligament and/or an avulsion fracture of the medial malleolus.
