FEA, Biomechanical and Clinical Study of R.O. Peritrochanteric Fractures With PFLP vs Cephalomedullary Nail.

Hip fractures are the second most common fracture regardless of age, while at the same time its incidence is on the rise and it is expected to keep increasing in the future. In addition, hip fractures oppose a serious problem for both patients and clinicians, as they are associated with high rates of morbidity, reduced quality of life, impeded independent functionality and higher institutionalization rates. Several osteosynthesis techniques have been proposed for surgical correction of hip fractures which can be grouped into 3 main categories: a) Dynamic Hip Screw (DHS) extramedullary systems, b) Proximal femoral nail N \[PN\] PFNA\], γ-nail \[GN\] or other implants) and (c) Dynamic Condylar Screw, Angled blade plates, Proximal Femur Locking Plate (PFLP). This study will compare the use of anatomical proximal femur locking plates ( PeriLock, Smith\& Nephew) with an intramedullary nailing system, one of the most common and literature supported implants for the reduction of reverse oblique intertrochanteric fractures, classified as A31- 1,3 according to AO. The study will include Biomechanical testing and finite element analysis of the implants in an experimental setup using artificial bones performed at the Laboratory of Technology and Strength of Materials of the Department of Mechanical Engineering and Aeronautics of the University of Patras. and a pilot, prospective, randomized clinical study in a sample of 30 patients divided into 2 groups, where comparison of perioperative and intraoperative data will be accessed. The purpose of this study is to evaluate the efficacy and mechanical stability as wells as the clinical and radiological parameters as well as quality-of-life indicators in patients with reverse oblique hip fractures The primary goal of to investigate whether there are statistically significant differences in the main radiological parameters (cut-out, misalignment of the femoral head, loss of alignment, defective posture, non-union), while The second
