Biomechanical effects of three different configurations in Salter Harris type 3 distal femoral epiphyseal fractures

Biomechanical Effects of Four Different Configurations In Salter Harris Type 4 Distal Femoral Epiphyseal Fractures

“…In the treatment of femur distal epiphysis SH type 4 fractures, parallel screw or K wires between physis and joint can be used [10,11,16].However, there is no biomechanic evidence showing that which one is stronger in fracture stability in fixations done with screw or K wires. In addition, in these fixations, issue about in which technic stress load applied on the physis under force is less or more is still not very clear [17].In our study, when displacive forces reflected to fracture in physis line evaluated; the lowest stress values in axial forces in longitudinal plan were found by using parallel screw configuration in physis line. When we look at the literature there was no study about the physis after which fixation at which rate it was carrying the stress load [17].…”

“…In our study, when displacive forces reflected to fracture in physis line evaluated; the highest stress values in axial forces in longitudinal plan were found by using parallel K wire configuration in physis line. In this study, the fixation shape of K wire on the upper and lower configuration was found to be disadvantageous compared to other fixation configurations in the SH type 4 epiphyseal fractures.In another paper by Gok et al [17], they have been found particularly advantageous to use fixation type in screw configurationin SH type 3 epiphyseal fracture.The distal epiphyseal fractures of femur have a high risk of especially growth delay and other morbidities [3][4][5][6]. There are some factors considered as the cause of this situation as follows.…”

“…There are some factors considered as the cause of this situation as follows. The age of the person, type of fracture, degree of shear, sinuous structure of physis, quality of fracture reduction process and fixation shape [7][8][9][10].Thereis no final proof of evidence or biomechanical research that highlight which factors were effective in the formation of iatrogenic epiphysiodesis (bar formation and consequently growth interruption) in this area [17]. In contrast, in many studies growth retards was related to the fracture fixation of this type of fracture [33].According to our results, it has been found particularly advantageous to use fixation type in parallel screw configuration.…”

“…Second, all the operations were open, and the closed reduction and internal xation guided by the guidance should be further carried out in the later. Finally, we don't distinguish the level of K-wires and the distance between the K-wires, nite element analysis [18][19][20] can be carried out for comparison in the future.…”

Should we really compress the fracture line in the treatment of Salter–Harris type 4 distal femoral fractures? A biomechanical study

“…It is also used as a reliable technique for validation of experimental or analytical results. In addition, several scientists similarly examined the optimal configuration, implant materials, fatigue behavior of implant materials, metal turning, bone drilling and bone screwing process using the computer-aided FEA tool [22][23][24][25][26][27][28].…”
