Abstract:

Implant devices, systems, and methods are used to prevent post-surgical dislocation of a surgically reconstructed ball-and-socket joint, while retaining the patient's range of motion. The implant device can have a cup having a substantially hemispherical inner contour; a head at least partially inserted within the cup, the head having an outer contour that is generally spherically-shaped, and an elastic retainer with an inner contour that is at least a cross-sectional segment of a spherical shape having substantially a same radius as the inner contour of the cup, the elastic retainer being attachable over an open end of the cup to retain the head within the cup and allowing the outer contour of the head to freely rotate and/or pivot against the inner contour of the cup over the predetermined range of motion of the ball-and-socket joint.
