It is estimated that in the United States 320,000 people -- mostly elderly and women -- sustain this fracture that results in their hospitalization. These fractures mostly occur due to a low-energy fall. In one study from the UK it was noted that patients over age 82 (± 7 years) fared badly after this fracture and the mortality was estimated to be between 20 and 35% in one year. Majority of these patients (80%) were women.
The rounded head of the femoral bone and the hollow socket in the hip bone called the acetabulum works in a 'ball and socket' arranegement. In fracture of the neck of the femur, and the head and neck of the femur is often replaced by prosthesis and this is termed as Hemi-arthroplasty of the hip. When both head and the hollow socket (acetabulum) of the hip bone are replaced by prostheses it is called 'Total Hip Replacement.'
If the fracture is below the neck of femur (inter-trochanteric), a sliding compression screw maybe used to fix the fracture.
Fracture of the femur neck is also called "a fracture of necessity"
among the orthopedic fraternity, in other words it is a kind of fracture that needs to be operated upon for optimal results.
