Analytical modelling of Kirschner wires in Ilizarov circular external fixator as pretensioned slender beams.
Transfixing thin Kirschner wires (K-wires) are the key components of the Ilizarov fixator regarding its axial stiffness, which affects the mechanobiological environment in which bone is healed. Mechanically speaking, K-wires are slender beams that are axially tensioned, then fixed and transversely loaded. The existing solutions to such a problem either do not accommodate any axial loading prior...
متن کاملTheoretical and Finite Element Modeling of Fine Kirschner Wires in Ilizarov External Fixator
The mechanical behavior of the transosseous elements is a defining factor in the overall stiffness, stability, and reliability of an external fixation system. Mechanics involving the application of thin Kirschner wires in Ilizarov apparatus is yet to be fully explained. To address this problem, load-deflection behavior of the pretensioned thin wires laterally loaded by the bone is necessary to ...

متن کاملStabilization of forearm fractures in children using intramedullary Kirschner wires.
Background. Minimally invasive intramedullary stabilization is a widely accepted method for treating long bone fractures in children. Indications concerning age and type of fracture have increased in the last decade. The aim of our study was to assess outcome in intramedullary Kirschner wire stabilization used to treat forearm fractures in children. Material and methods. From 1997 to 2004 intra...
متن کاملFE parametric analysis of nonlinear mechanical behaviour of Ilizarov external fixator
The study describes a computational approach for predicting the mechanical response of different configurations of the Ilizarov external fixation system. The Ilizarov type fixators are now being used to an increasing extend to stabilize bone fractures and for limb lengthtening [5,6] and its functions are investigated using numerical [e.g. 3,7] and experimental [e.g. 1,2] techniques. The device ...
