What is osseous avulsion?
An avulsion fracture is an injury to the bone in a location where a tendon or ligament attaches to the bone. When an avulsion fracture occurs, the tendon or ligament pulls off a piece of the bone.
What is Ununited medial epicondyle?
Abstract. A calcified fragment near the medial epicondyle of the humerus was originally described as an ununited medial epicondyle in 1966. Since then several papers reported similar lesions as a cause of elbow lameness. The aetiology and clinical significance of those lesions is poorly known.
What is humerus epicondyle?
Latin. Epicondylus medialis humeri. TA98. A02.4.04.027. TA2.
What is an epicondyle fracture?
A medial epicondyle fracture is an avulsion injury of the attachment of the common flexors of the forearm. The injury is usually extra-articular but can be sometimes associated with an elbow dislocation.
What is a bone Fleck?
The fleck sign in the foot is a small bony fragment seen in the Lisfranc space (between the base of the 1st and 2nd metatarsal) associated with avulsion of the Lisfranc ligament (at the base of the 2nd metatarsal). It is a very subtle, but important finding, since it predisposes to Lisfranc injury.
What is an avulsion fracture of the knee?
An avulsion fracture occurs when an injury causes a ligament or tendon to break off (avulse) a small piece of a bone that’s attached to it. The ligament or tendon also may be damaged. This type of injury can happen in the hip, ankle, knee, heel, elbow, or pelvis.
What is femur epicondyle?
The medial epicondyle of the femur is an epicondyle, a bony protrusion, located on the medial side of the femur at its distal end. Located above the medial condyle, it bears an elevation, the adductor tubercle, which serves for the attachment of the superficial part, or “tendinous insertion”, of the adductor magnus.
What is the function of the lateral epicondyle?
Anatomical terms of bone The lateral epicondyle of the humerus is a large, tuberculated eminence, curved a little forward, and giving attachment to the radial collateral ligament of the elbow joint, and to a tendon common to the origin of the supinator and some of the extensor muscles.
What is a chip fracture in the ankle?
Chip fractures are the sign of ligament rupture on the inner side of the ankle. Rather than the force of the injury-causing a bone break, the ligaments pull off directly where they attach to the bone. The ligament can pull off a small piece of bone as the ligament is ruptured.
What is a chip fracture?
An avulsion fracture happens when a ligament or tendon pulls part of your bone off. This usually happens as the result of a traumatic injury. Avulsion fractures commonly occur in the hip, elbow, and ankle in young people who play sports.
