ABSTRACT:
A halo system orthopedic appliance includes an adjustable two poster arrangement in which the connections between the respective posts and the appliance are made with respective clamp mechanisms. Each poster is slidably received in a channel formed by each clamp. Each clamp is rotatably received on a single clamp screw which when tightened simultaneously fixes the slidably adjusted position of the post relative the clamp and the rotatably adjusted position of the clamp relative the appliance. Serrations on opposing surfaces between respectively paired clamps and adapter brackets carried on the halo ring, and respectively between two clamps and superstructure supported on a patient vest, enhances the clamping effect. During application of the appliance, the patient's skeletal process is first aligned in a desired orientation, and thereafter the four respective clamps located adjacent each end of the pair of posters are secured. The two poster arrangement and single clamp screw per clamp advantageously permits rapid alignment, adjustment, and securement of the orthopedic appliance to a patient. Relative bulk of the appliance is also reduced for imaging and aesthetic advantages.
