Abstract: Disclosed herein is an undergarment device for treating hip displacement and hip dislocation. The device includes a panty member having a first open position generally in the shape of a rectangle and a second position wherein the panty member is wrapped around the hips of a user. The longer sides of the rectangle shape covers the front and back of a user in the second position and the shorter sides cover the sides of a user and extend past the hips to the legs in the second position. Each of the longer and shorter sides intersect at vaulted recesses defining openings for a user's legs in the second position. The panty member includes structure for fastening the device to itself. The panty member further includes a valve on one of the layers for allowing fluid, such as air, to be injected between the layers for spacing apart the layers. Upon placing the device around the hips of a user and fastening the device to itself and injecting fluid between the layers, the hips of the user are supported by the device.
