Fractures of proximal femur include intra capsular fractures –neck of femur, extra capsular fractures –inter trochanteric fractures and sub trochanteric fractures. These account for over half of all the femoral fractures. 95% occur in patients greater than 50 years of age. These result in a 1-year mortality rate of 12-18%. Femoral neck fractures in younger patients result from high-energy trauma or stress fractures.
