What device is used to maintain hip alignment after hip replacement?

• A. Abductor pillow
• B. Trochanter roll
• C. Knee immobilizer
• D. No device

Answer: (A)

After a hip replacement, keeping the new joint in the proper position is essential to prevent dislocation. An abductor pillow placed between the legs helps maintain abduction and neutral rotation, especially when the patient is on their back or turning in bed. By preventing the legs from crossing and rotating inward, the pillow directly reduces the risk of dislocation during the early post-op period and with repositioning. A knee immobilizer is intended for knee stabilization and doesn’t address hip alignment. A trochanter roll is used in some settings to help keep the leg aligned in bed but doesn’t specifically ensure the abduction needed after hip replacement. So, the abductor pillow is the device that best maintains hip alignment in this scenario.
