Which term is an injury occurring when the end of a bone comes out of its socket at the joint?

• A. Dislocation
• B. Diabetes
• C. Depth Perception
• D. Defensive Tactics

Answer: (A)

Dislocation is when the end of a bone is forced out of its socket in a joint, so the joint becomes misaligned. This leads to sharp pain, swelling, deformity, and a marked inability to move the joint normally. The injury can also damage surrounding ligaments, tendons, nerves, or blood vessels, so it usually requires prompt medical realignment (reduction) and assessment for tissue injury. Do not try to pop it back in yourself—stabilize the area, apply ice, and seek medical care. Sometimes a partial displacement is called a subluxation, where the joint is only partly out of place. This concept is distinct from conditions like diabetes or perceptual abilities, or skills used in self-defense, which are unrelated to joint injuries.
