Purpose The purpose of this study was to describe a novelbone lengthening plate (BLP) and to evaluate the biomechanicalperformance of the plate before clinical use. Methods A finite element model was obtained from valuesof the compression test. It was used to evaluate the performanceof the BLP, such as biomechanical stability and structuralstiffness, according to materials of the shaft and column usedfor lengthening (type I: all Titanium-alloys, type II and III:Titanium-alloys and Cobalt-Chrome-alloys, type IV: allCobalt-Chrome-alloys). Furthermore, Peak von Mises Stress,risk of screw breakage, and micro-motion between the boneand screw were evaluated. Results Structural stiffness and strain of the finite elementmodel of the femur were similar to cadaveric femurs. Structuralstiffness increased from type I (Titanium alloys) to type IV(Cobalt-Chrome-alloys) by at least 128%. First locking screw,which was inserted at the osteotomy site of the proximalfemur (proximal to distal direction), showed the highest riskof breakage (75%). Conclusions This study investigated biomechanical stabilityof the novel BLP in relation to properties of the supportingstructures. It was most biomechanically stable when thecolumn and lengthening shaft were composed of Cobalt-Chrome-alloys (type IV).
