Evaluation of Gamma Nails in Intertrochanteric Fractures of Femur and Modified Technique for Removal

摘要

Intertrochanteric fractures of femur (IFF) that comprise 8% - 10% of all fractures are most commonly seen in people over 65 years old. Fractures of this region not only affect general state of health of patients, but also affect their lives mentally, socially and economically. Sufficient reduction and rigid internal fixation are still the best method for unstable IFF. Because of its biomechanical and anatomical design, proximal femoral nail (PFN) is a fixation material that has started to be increasingly used by orthopedic surgeons recently. In orthopedic traumatic surgery, implant failure is one of the most serious complications. To avoid these complications, many surgical techniques have been reported. Break of intramedullary nails especially in case of a nonunion requires to be extracted, which is a very difficult and challenging procedure for the surgeon. Many methods and materials have been described for this procedure. In this study we aim to review these topics.
