Proximal femoral fixation nail in proximal femoral fractures- study on biomechanical forces causing implant failure
Journal Title: Indian Journal of Orthopaedics Surgery - Year 2017, Vol 3, Issue 1
Abstract
Objective: Purpose of this study is to evaluate biomechanical factors working around hip which leads to implant failure. Knowledge of these biomechanical forces may help in some modification in implant design or developing new operative techniques[ to avoid damage or to strengthen protecting forces working on implant] and it may also help in developing some new postop splint support for patient benefit. Material and Methods: This is a prospective cum retrospective study. All 11 cases with proximal femoral fracture[ # I/T & S/T included] fixed with PFN. Conclusion: To prevent implant failure biomechanical force-vectors has to be compensated by forces generated in opposite direction either by body itself or biomechanical properties of implant either due to its specific design or due to properties of material which is used. If not compensated implant failure may occure.
