Which statement describes a dislocation?

• A. Bone comes out of a joint
• B. Hairline fracture
• C. Torn ligament
• D. Bruise

Answer: (A)

Dislocation means a bone is forced out of its normal position in a joint, so the joint often looks deformed, with severe pain and little or no ability to move it. That description matches the statement that a bone comes out of a joint. The other injuries describe different problems: a hairline fracture is a small crack in the bone, not the bone leaving the joint; a torn ligament is a sprain affecting the surrounding soft tissue, not bone displacement; a bruise is soft tissue damage under the skin with discoloration but no joint displacement. If you suspect a dislocation, don’t try to push the bone back in. Stabilize the limb in the position found, immobilize it with a splint or sling, and seek medical care. Check for circulation beyond the injury (pulse, color, sensation), apply ice to reduce swelling (with a layer of cloth between skin and ice), and monitor for signs of shock while waiting for help.
