Which statement accurately describes subluxation?

Which statement accurately describes subluxation?

• A. It is a complete dislocation with permanent misalignment
• B. It is a partial dislocation that may spontaneously reduce
• C. It is a fracture with fragments
• D. It only occurs in joints of the hand

Answer: (B)

Subluxation is a partial dislocation of a joint, meaning the joint surfaces are out of alignment but still in contact with each other. The hallmark is partial displacement with the possibility that the surfaces can return toward normal alignment on their own, sometimes spontaneously reducing. This distinguishes it from a full dislocation, where the bones lose contact entirely and usually require reduction to reestablish alignment. It’s also not a fracture with fragments, which is a different kind of injury involving broken bone pieces, and subluxations can occur in many joints, not just in the hand. In practice, you’d expect local pain, swelling, and limited movement, with careful evaluation to ensure there’s no associated injury to nerves, blood vessels, or a fracture.
