The head of the femur is joined to the bone shaft by a narrow piece of bone called the neck of the femur, which is a common fracture site. St the lower end, the bone is enlarged to from two lumps that distribute the weight-bearing load through the knee joint. On the outer side of the upper femur is a protuberance called the greater trochanter.
The shaft of the femur is surrounded by muscles that move the hip and knee joints. The shaft is also well supplied with blood vessels, therefore a fracture can result in considerable blood loss.
A break in the femur (the thigh bone). The symptoms, treatment and possible complications of a fracture depend on whether the bone has broken across its neck (the short section between te top of the shaft and the hip joint) or across the shaft.
This type of fracture, which is often called broken hip, is very common in elderly people, especially in women with the bone disorder osteoporosis. It is usually associated with a fall. In a fracture of the neck of the femur, the broken bone ends are often considerably displaced, in such a cases there is usually severe pain in the hip and groin, making standing impossible. Occasionally, the broken bone ends become impacted. In this case, there is less pain, and walking case, there is less pain and walking may be possible.
The diagnosis is confirmed by X-ray. If the ends of the bone are displaced an operation is necessary.
