Which joint condition describes a situation where the bone returns to normal alignment without external manipulation?

• A. Dislocation
• B. Subluxation
• C. Fracture
• D. Sprain

Answer: (B)

When a joint misalignment corrects itself without anyone having to push it back into place, that describes a subluxation. A subluxation is a partial or transient misalignment of the joint that can reduce (go back into proper position) on its own, often with the joint still maintaining some contact between the surfaces. This contrasts with a full dislocation, where the joint surfaces are completely out of contact and usually need deliberate reduction to restore alignment. A fracture is a break in the bone, not just a joint alignment issue, and a sprain is an injury to ligaments without the joint surfaces losing and regaining contact. So the scenario fits subluxation best.
