For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without breaking. Their secret lies in tiny, line-like defects called dislocations, ...

An anterior shoulder dislocation occurs when the shoulder slides forward out of the socket. It is usually the result of a sports injury, fall, or traffic accident. This shoulder injury is the most ...

Posterior shoulder dislocation occurs when the top of the upper arm bone, known as the humerus, moves backward out of its socket. This causes pain, muscle spasms, and a limited range of motion. The ...

Understanding how dislocations (line defects in the crystal structure) occur when 3D-printing metals has been unclear to materials scientists. Understanding when and how dislocations form in ...

A dislocation is a joint injury in which the bones are forced out of their usual positions and are completely separated. Your joints are where two or more bones meet. It can be hard to tell if a bone ...

Shoulder dislocations are one of the most common kinds of shoulder injuries and should be treated by a medical professional (popping it back into place like a character in an action movie is NOT a ...
