In this study, the biomechanicaleffects of four different configurations (Parallel K wires, Parallel Screw, Upper K wire-Lower Screw, Upper Screw-Lower K wire), which are used for stabilizing Salter-Harris (SH) Type 4 epiphyseal fracture of distal femur after reduction process, on the epiphyseal plate has been investigated under axial, rotational and bendingforces in order to determine the most advantageous configuration. The fourdifferent configurations have been modeled by using SolidWorks and computer-aided numerical analyses were performed by finite element analysis software. The mesh process, boundary conditions and material model have been applied in finite element analysis software for each configuration. In addition, von-Mises stress values on epiphyseal plate, screws and K wires have been calculated. There is a general near trend on stress values in all configurations on physis line under bending (varus-valgus angulation, anterior-posterior angulation) and torsional forces in the frontal, sagittal and transverse plane respectively. Considering the axial forces, the highest stress was found on parallel K- wires configuration in physis while the lowest stress was found in parallel screw configuration. It has been found particularly advantageous to use fixation type in parallel screw configuration. In addition, in SH type 4 epiphyseal fracture, fixation type is found to be disadvantageous in K wire configuration.

Bu çalışmada, distal femurun Salter Harris (SH) Tip 4 epifiz kırığında redüksiyon sonrası stabilizasyon için kullanılan Parallel K-wires, Parallel Screw, Upper K-wire-Lower Screw, Upper Screw-Lower K-wire olmak üzere 4 farklı konfigürasyonun, aksiyel, rotasyonel ve eğme kuvvetleri altında,  biyomekanik etkilerini tanımlayıp hangisinin daha avantajlı olduğu araştırıldı. 4 farklı konfigürasyon SolidWorks programı ile modellendi ve bilgisayar destekli sayısal analizler sonlu elemanlar yazılımı ile gerçekleştirildi. Herbir konfigürasyon için, ağ süreci, sınır şartları ve malzeme modeli sonlu elemanlar yazılımında uygulandı. Buna ek olarak, epifiz plağının gelişimindeki von-Mises gerilme değerleri, vidalar ve K-tellerindeki gerilme değerleri hesaplanmıştır. Frontal, sagittal ve transvers düzlemde bükme (varus-valgus açılımı, ön-arka açısal kapanma) ve burulma kuvvetleri altındaki fizis çizgi üzerinde tüm konfigürasyonlarda gerilme değerlerinde genel olarak yakın bir eğilim vardır. Eksenel kuvvetler düşünüldüğünde, en yüksek gerilme, fisizte paralel K-telleri konfigürasyonunda bulunurken, en düşük gerilme paralel vida konfigürasyonunda bulundu. Paralel vida konfigürasyonunda fiksasyon tipinin kullanılması avantajlı bulunmuştur. Ek olarak, SH tipi 4 epifiz kırıklarında, K-teli konfigürasyonunda fiksasyon tipi dezavantajlı bulunmuştur.
