Abstract
A tapered spring friction clamping assembly replaced the bolted grip and hold assembly of the Ilizarov wire tensioning device. An integrated force transducer records the wire tension and according to the physician’s instructions the patient adjusts himself the K-wire tension. Analytical solutions of the K-wires axial stress in relation with transverse loading provide the basis for the design of different gripping configurations to adapt different applications needs regarding K-wire length and diameter, varying tension force requirements, and different force transducers configurations. The proposed method provides design flexibility, and operational validation of this new Ilizarov fixator.
