What is the purpose of a trochanter roll?

The purpose of a trochanter roll is primarily to prevent external rotation of the hip. This supportive device is typically used for patients who are immobilized or have limited mobility, particularly in rehabilitation or post-operative settings. When a patient is in a supine position (lying on their back), the hips can inadvertently rotate outward, which may lead to complications like hip dislocation or improper alignment.

A trochanter roll is placed alongside the hip, extending from the greater trochanter down to the mid-thigh, and it helps keep the femur aligned properly. By stabilizing the leg, the trochanter roll effectively prevents the hip from rotating outward, promoting better joint integrity and aiding in recovery. This is crucial for individuals who may be at risk for complications due to immobility or surgery, making this intervention an important aspect of patient care in certain clinical scenarios.
