What device is commonly used to maintain proper alignment of a patient who has sustained a hip fracture?

The abduction pillow is specifically designed to maintain proper alignment of the hips after a hip fracture or hip surgery. It is used to prevent the legs from crossing or coming together, which is a crucial aspect of recovery to avoid dislocation and promote healing. By keeping the legs apart, the abduction pillow helps support the hip joint in a stable and safe position.

Other options do not serve the same purpose in the context of a hip fracture. A compression bandage is primarily used to control swelling and support injured tissues, rather than to maintain alignment. A wedge cushion can provide comfort and positioning but is not specifically designed for the alignment of hip fractures. A foam roller is generally used for muscle relaxation and improving circulation, rather than for patient stabilization or alignment in post-operative care. Thus, the choice of the abduction pillow aligns with the clinical need for maintaining proper hip positioning after such an injury.
