Which sign indicates a possible hip dislocation after a hip replacement?

• A. Numbness in the toes
• B. Swelling in the ankle
• C. Leg shortened and foot turned inward
• D. Paleness of the skin

Answer: (C)

When a hip dislocation occurs after a hip replacement, the leg position gives the clearest clue. The affected leg often looks shortened and the foot turns inward because the femoral head has slipped out of the socket and changes the leg’s alignment. This combination is a strong, specific sign of dislocation and should prompt urgent medical evaluation. Other signs like numb toes, swelling at the ankle, or pale skin can reflect nerve issues, swelling, or circulation problems unrelated to a dislocation, so they aren’t as directly indicative in this context. If you notice the leg shortened and the foot rotated inward, seek emergency care right away and avoid moving the leg.
