How is a femur shaft fracture diagnosed?
In some cases, if the patient falls and complains of hip pain, an incomplete fracture may not be seen on a regular X-ray. In that case, magnetic resonance imaging (MRI) may be recommended. The MRI scan will usually show a hidden fracture.
If the patient is unable to have an MRI scan because of an associated medical condition, computed tomography (CT) may be obtained instead. Computed tomography, however, is not as sensitive as MRI for seeing hidden hip fractures.
What are different types of hip fractures?
In general, there are three different types of hip fractures. The type of fracture depends on what area of the upper femur is involved.
These fractures occur at the level of the neck and the head of the femur, and are generally within the capsule. The capsule is the soft-tissue envelope that contains the lubricating and nourishing fluid of the hip joint itself.
This fracture occurs between the neck of the femur and a lower bony prominence called the lesser trochanter. The lesser trochanter is an attachment point for one of the major muscles of the hip. Intertrochanteric fractures generally cross in the area between the lesser trochanter and the greater trochanter. The greater trochanter is the bump you can feel under the skin on the outside of the hip. It acts as another muscle attachment point.
This fracture occurs below the lesser trochanter, in a region that is between the lesser trochanter and an area approximately 2 1/2 inches below. In more complicated cases, the amount of breakage of the bone can involve more than one of these zones. This is taken into consideration when surgical repair is considered.
