What is an avulsion?

An avulsion refers specifically to the separation of a tendon or ligament from its bony attachment. This injury occurs when a strong force pulls on a tendon or ligament, causing it to detach from the bone it is connected to, often accompanied by a small piece of bone being pulled away as well. This type of injury is commonly seen in athletes, particularly during activities that require sudden movements or changes in direction, where forceful traction is applied to the muscle-tendon unit.

Understanding avulsions is critical in the context of musculoskeletal injuries because they require specific treatment approaches and rehabilitation to ensure proper healing and restoration of function. Different from the other options listed, an avulsion is characteristically distinct, as it involves the connective tissue and its interface with bone, rather than the joint surfaces, complete fractures, or joint sprains that involve other types of injuries and associated symptoms.
