Final answer:
An abducter pillow is used post-hip replacement to keep the hip in the correct position, assist with leg movements, and stabilize the iliotibial track, which is essential for knee stability.
Step-by-step explanation:
After a hip replacement surgery, it is crucial to maintain the correct positioning of the hip to ensure proper healing and prevent dislocation. An abducter pillow is typically placed between a patient's legs to help maintain the hip in a straight and neutral position. This assists the patient with raising the knee at the hip and opening the thighs. Furthermore, the use of an abducter pillow aids in maintaining posture by stabilizing the iliotibial track, which connects to the knee. This is useful because the iliotibial track is essential for knee stability and function.
