Proximal femoral nail for treatment of trochanteric femoral fractures.
PURPOSE To report outcomes of 87 consecutive patients treated with a proximal femoral nail (PFN) for trochanteric femoral fractures. METHODS 17 men and 70 women aged 58 to 95 (mean, 85) years with trochanteric femoral fractures underwent PFN fixation using an intramedullary nail, a lag screw, and a hip pin. Fractures were classified according to the AO system; the most common fracture type wa...
متن کاملBiomechanical comparison of dynamic hip screw and Gamma nail for the treatment of unstable trochanteric fractures: a finite element study
Objectives: To investigate the biomechanical behavior of the femur with two different implant configurations, namely dynamic hip screw and Gamma nail, in the treatment of two types of unstable intertrochanteric femoral fracture. Methods: A 3D finite element model of the intact proximal femur was constructed, from which two types of fractured models (AO classification 31-A2 and 31-A3) were produ...
متن کاملAugmentation of proximal femoral nail in unstable trochanteric fractures
INTRODUCTION Biomechanically proximal femoral nail (PFN) is a better choice of implant, still it is associated with screw breakage, cut out of screw through femoral head, Z effect, reverse Z effect, and lateral migration of screws. The purpose of this study is to evaluate the results of augmented PFN in terms of prevention of postoperative complications and failure rates in unstable trochanteri...
متن کاملTreatment of unstable trochanteric fractures. Randomised comparison of the gamma nail and the proximal femoral nail.
The proximal femoral nail (PFN) is a recently introduced intramedullary system, designed to improve treatment of unstable trochanteric fractures of the hip. In a multicentre prospective clinical study, the intra-operative use, complications and outcome of treatment using the PFN (n = 211) were compared with those using the gamma nail (GN) (n = 213). The intra-operative blood loss was lower with...
متن کاملManagement of Pertrochanteric Fractures with Proximal Femoral Nail and Comparison of Results with Dynamic Hip Screw
Introduction: Proximal Femoral Nail and Dynamic Hip Screw, both are the accepted implants for the internal fixation of Pertrochanteric fractures. Objectives of the research were to compare the results of proximal femoral nail and dynamic hip screw in terms of functional mobility of the patients and the results would also be compared in terms of operating time, peri-operative blood loss, radiolo...
