Hip fractures are a growing concern around the world as the geriatric population increases rapidly. The purpose of this study was to assess the impact of proximal femoral nailing on elderly. Despite the fact that intertrochanteric fracture fixation is generally successful, treatment is difficult when fixation fails. The purpose of this study was to assess the efficacy of an evidence-based protocol designed for the treatment of failed intertrochanteric fractures. When treating an unstable intertrochanteric fracture, there is a lesser risk of implant failure and reoperation, as well as a better postoperative functional recovery is seen. But in some rare cases some implant failures are major and requires a long-term treatment. Intertrochanteric femur fractures, particularly those with unstable patterns, are increasingly being treated with intramedullary implants. Despite the widespread use of nails in the treatment of these fractures, perspectives on the proper length of an intramedullary nail differ. Long nails were created to alleviate the risk of diaphyseal fracture that came with prior short nail designs. The main aim is to govern the unstable nail fixation of the intertrochanteric femoral fractures.
