The femur or thigh bone is frequently injured in children. They are usually the result of significant trauma such as a fall from a height or a motor vehicle accident. With proper treatment, most femur fractures heal properly.without permanent problems.
There are a variety of treatments for femur fractures in children, depending on the age of the patient, type of fracture, and location in the bone. Infants and toddlers can usually be treated with a spica (body) cast. Older children may require surgery depending on the severity of the injury and its location. Rods are commonly used to treat femur fractures in older children, as well. Flexible rods that are inserted into the hollow center of the bone are the most common, but in some cases a solid rod or an external fixator may be appropriate. Children over the age of 12 are more likely to have a femur fracture treated the same as an adult would.
While perfect alignment is often sought in adult patients, children have the advantage of growth and the ability to remodel the bone with time. Thus, your surgeon may leave the bones overlapped or slightly displaced since with time it will straighten on its own.
Anatomy of the Femur
The head of the femur is fairly round and sits within a cup known as the acetabulum. This forms the hip joint. The shaft runs down the thigh and is covered in the front by the quadriceps muscle. At the end by the knee, it flairs and has rounded areas called condyles that form the knee joint with the upper end of the tibia and the patella (or knee cap). There is a growth plate within the femoral head at the top, and also a growth plate at the level of the condyles.
