The orthopedic support pillow is for use by a patient having a retained arm while the patient is lying in a generally prone position sideways on a resting surface. The orthopedic support pillow comprises two side surfaces, the two side surfaces opposing each other, and a bracing surface. The second side surface accommodates the retained arm of the patient and is at least as wide as the ailing forearm of the patient. The bracing surface is disposed between the two side surfaces, and has a generally concave shape. The abdominal section of the patient abuts against the bracing surface of the orthopedic support pillow when the patient is lying in the prone position sideways. The orthopedic support pillow provides stability and support to the retained arm in an elevated position while the patient is in the generally prone position on the resting surface. The orthopedic support pillow includes a strap or pocket positioned for retaining the hand of retained arm of the patient. The orthopedic support pillow is either made of a resilient foam material, or has an inflatable pillow body with an interior that is adapted to be filled with air inflate the pillow body, enabling firmness of the orthopedic support pillow to be adjusted for comfort by each patient.
