    Patent number: 5437668
    Abstract: Distraction Osteogenesis is a procedure for lengthening a bone. The Ilizarov External Fixator is an apparatus employed in the distraction osteogenesis procedure. The prospects for a successful clinical outcome of the procedure are enhanced by modifying the Ilizarov apparatus to obtain measurements of loads generated during the procedure. An apparatus and method for the clinical use of load measurements taken during the distraction osteogenesis procedure are disclosed. An alternative method is disclosed for converting load measurements to stress data in order to enhance the clinical outcome of the procedure.
