  • Publication number: 20230201020
    Abstract: An orthopedic sacroiliac brace is provided. The brace includes a belt portion including a first posterior sacral panel coupled to the belt portion and configured to be disposed directly posterior of a first posterior side of an ilium of a user, and a second posterior sacral panel coupled to the belt portion and configured to be disposed directly posterior of a second posterior side of the ilium. Adjustably tightening the belt portion around the user causes the first and second posterior sacral panels to apply respective anterior forces to the first and second posterior sides of the ilium, thereby providing adjustable stabilizing support, compression and/or alignment to a sacroiliac joint of the user. Brace can also include an anterior abdominal panel configured to be disposed against an anterior portion of an abdomen of the user and coupled to the belt portion.
