title: The study and development of a connection device (D.R. IOR) in halo-plaster and halo-jacket immobilization and traction systems.
abstract: Most of the halo connection devices currently used with both the halo-plaster and halo-vest cannot be adjusted on the different displacement planes during reduction treatment. This makes it difficult to obtain good radiograms for the interposition of connection bars. The connection device designed by the Rizzoli Orthopaedic Institute (D.R. IOR) allows for movements in rotation and translation, preventing loosening of the system. Moreover, radiographic monitoring may be obtained in the best conditions possible, by moving the connection rods backwards or forwards without changing the spinal axis.
