Resumo: | Abstract Objective The aim of the present study is to investigate the biomechanical stability of different subtrochanteric osteotomy types and graft positions in cases of dysplastic coxarthrosis that require total hip arthroplasty with shortening osteotomy, as well as to find out the most effective osteotomy type and graft position. Method Femur sawbones were used to compare different types of femoral shortening osteotomy (transverse, oblique, and step-cut). Strut grafts, which were prepared at the side of the subtrochanteric shortening osteotomy, were fixed in different positions (anterolateral, mediolateral, and anteroposterior). The fixation of the strut grafts was performed using two steel cables (with 2.0mm of thickness) with the same strength. The failure values of composite femurs were recorded for axial and rotational loadings. Results Biomechanically, there were no statistically significant differences between the types of femoral subtrochanteric shortening osteotomy and the positions of the applied strut graft. Conclusion No superiority was observed between the types of femoral subtrochanteric shortening osteotomy regarding stability. Additionally, against stress, similar results were obtained for different strut graft positions. In conclusion, we believe that using the method in which the surgeon is experienced and that is the easiest to apply would be the best choice. |
