What defines a dislocation?

A dislocation is defined as a bone being pulled out of its joint, which disrupts the normal anatomy and function of the joint. This occurs when the ends of the bones that form a joint are forced out of their normal positions, resulting in pain, swelling, and difficulty moving the affected limb. Dislocations often require medical intervention to realign the bones properly, as well as pain management and rehabilitation to restore normal function.

In contrast, other conditions like a fracture involve the breaking of a bone but do not necessarily involve a joint, while inflammation of tendons surrounding a joint refers to tendinitis or bursitis, which is a tissue injury rather than a dislocation. The option stating a separation of two bones that do not touch is not an accurate depiction of how dislocations function, as dislocation specifically pertains to the displacement of bones within a joint context.
