Biomechanical Analysis of Unilateral External Skeletal Fixators Combined with IM‐Pin and Without IM‐Pin Using Finite‐Element Method

Abstract: Based on the results of this FEM study we recommend the use of the "tied-in" IM-pin with the ESF clinically when striving for high rigidity. In less challenging situations, a unilateral SK ESF without IM-pin might provide sufficient rigidity for a successful fracture repair.

“…Under quasistatic uniaxial compressive loading, the mean yield strength, yield energy, and ultimate strength of the tied-in configuration were mentioned to be significantly larger than those not tied (13). Also, based on the results of a finite element analysis study (17), the use of the "tied-in" IM pin with the ESF is recommended in challenging fractures. Another study (18) demonstrated that if IM pin is embedded well in the metaphysis when used together with a unilateral frame, unilateral ESF frames reveal an equivalent or even higher stiffness modulus compared to a bilateral frame with an identical half pin arrangement.…”

“…Early limb use promotes healing by allowing axial micromotion at the fracture site and also prevents inactivation atrophy in patients with bone fractures (11,17). This is very critical in large and giant breed dogs with multiple fractures.…”

“…Since then, several other studies have been conducted (6)(7)(8)(9)(10)(11) . Studies using this technique have also been published in the Brazilian literature, but not with simulation of an external fixator (12)(13)(14) .…”

“…The golden standart for a perfect ESF procedure is to construct frames that allow full weightbearing without interfering with the use of the limb. Early ambulation accelerates bone healing by stimulating axial micromotion at the fracture line and also prevents fracture disease such as disuse atrophy and muscle contractures [17,18] . This is critical in large breed dogs with concomitant injuries.…”
