FAQs on Femur Shaft Fractures (Broken Thighbone)
Femur Shaft Fractures (Broken Thighbone)
Your thighbone (femur) is the longest and strongest bone in your body. Because the femur is so strong, it usually takes a lot of force to break it. Car crashes, for example, are the number one cause of femur fractures.
The long, straight part of the femur is called the femoral shaft. When there is a break anywhere along this length of bone, it is called a femoral shaft fracture.
Types of Femoral Shaft Fractures
Femur fractures vary greatly, depending on the force that causes the break. The pieces of bone may line up correctly or be out of alignment (displaced), and the fracture may be closed (skin intact) or open (the bone has punctured the skin).
Doctors describe fractures to each other using classification systems. Femur fractures are classified depending on:
- The location of the fracture (the femoral shaft is divided into thirds: distal, middle, proximal)
- The pattern of the fracture (for example, the bone can break in different directions, such as cross-wise, length-wise, or in the middle)
- Whether the skin and muscle above the bone is torn by the injury
The most common types of femoral shaft fractures include:
Transverse fracture. In this type of fracture, the break is a straight horizontal line going across the femoral shaft.
Oblique fracture. This type of fracture has an angled line across the shaft.
Spiral fracture. The fracture line encircles the shaft like the stripes on a candy cane. A twisting force to the thigh causes this type of fracture.
Comminuted fracture. In this type of fracture, the bone has broken into three or more pieces. In most cases, the number of bone fragments corresponds with the amount of force required to break the bone.
Open fracture. If a bone breaks in such a way that bone fragments stick out through the skin or a wound penetrates down to the broken bone, the fracture is called an open or compound fracture.
Open fractures often involve much more damage to the surrounding muscles, tendons, and ligaments. They have a higher risk for complications — especially infections— and take a longer time to heal.
Femoral shaft fractures in young people are frequently due to some type of high-energy collision. The most common cause of femoral shaft fracture is a motor vehicle or motorcycle crash. Being hit by a car as a pedestrian is another common cause, as are falls from heights and gunshot wounds.
A lower-force incident, such as a fall from standing, may cause a femoral shaft fracture in an older person who has weaker bones.
A femoral shaft fracture usually causes immediate, severe pain. You will not be able to put weight on the injured leg, and it may look deformed — shorter than the other leg and no longer straight.
Medical History and Physical Examination
It is important that Dr. Backe know the specifics of how you hurt your leg. For example, if you were in a car accident, it would help your orthopedic surgeon to know how fast you were going, whether you were the driver or a passenger, whether you were wearing your seat belt, and if the airbags went off. This information will help Dr. Backe determine how you were hurt and whether you may be hurt somewhere else.
It is also important for Dr. Backe to know whether you have other health conditions like high blood pressure, diabetes, asthma, or allergies. Your doctor will also ask you about any medications you take.
After discussing your injury and medical history, Dr. Backe will do a careful examination. He or she will assess your overall condition, and then focus on your leg.
Your doctor will look for:
- An obvious deformity of the thigh/leg (an unusual angle, twisting, or shortening of the leg)
- Breaks in the skin
- Bony pieces that may be pushing on the skin
After the visual inspection, Dr. Backe will then feel along your thigh, leg, and foot looking for abnormalities and checking the tightness of the skin and muscles around your thigh. He or she will also feel for pulses. If you are awake, Dr. Backe will test for sensation and movement in your leg and foot.
Other tests that will provide Dr. Backe with more information about your injury include:
X-rays. The most common way to evaluate a fracture is with x-rays, which provide clear images of bone. X-rays can show whether a bone is intact or broken. They can also show the type of fracture and where it is located within the femur.
Computed Tomography (CT) scan. If Dr. Backe still needs more information after reviewing your x-rays, he or she may order a CT scan. A CT scan shows a cross-sectional image of your limb. It can provide Dr. Backe with valuable information about the severity of the fracture. For example, sometimes the fracture lines can be very thin and hard to see on an x-ray. A CT scan can help Dr. Backe see the lines more clearly.
Most femoral shaft fractures require surgery to heal. It is unusual for femoral shaft fractures to be treated without surgery. Very young children are sometimes treated with a cast. For more information on that, see Pediatric Thighbone (Femur) Fracture.
Timing of surgery. If the skin around your fracture has not been broken, Dr. Backe will wait until you are stable before doing surgery.
Open fractures, however, expose the fracture site to the environment. They urgently need to be cleansed and require immediate surgery to prevent infection.
For the time between initial emergency care and your surgery, Dr. Backe will place your leg either in a long-leg splint or in skeletal traction. This is to keep your broken bones as aligned as possible and to maintain the length of your leg.
Skeletal traction is a pulley system of weights and counterweights that holds the broken pieces of bone together. It keeps your leg straight and often helps to relieve pain.
External Fixation. In this type of operation, metal pins or screws are placed into the bone above and below the fracture site. The pins and screws are attached to a bar outside the skin. This device is a stabilizing frame that holds the bones in the proper position so they can heal.
External fixation is usually a temporary treatment for femur fractures. Because they are easily applied, external fixators are often put on when a patient has multiple injuries and is not yet ready for a longer surgery to fix the fracture. An external fixator provides good, temporary stability until the patient is healthy enough for the final surgery. In some cases, an external fixator is left on until the femur is fully healed, but this is not common.
Intramedullary Nailing. Currently, the method most surgeons use for treating femoral shaft fractures is intramedullary nailing. During this procedure, a specially designed metal rod is inserted into the marrow canal of the femur. The rod passes across the fracture to keep it in position.
An intramedullary nail can be inserted into the canal either at the hip or the knee through a small incision. It is screwed to the bone at both ends. This keeps the nail and the bone in proper position during healing.
Intramedullary nails are usually made of titanium. They come in various lengths and diameters to fit most femur bones.
Plates and Screws. During this operation, the bone fragments are first repositioned (reduced) into their normal alignment. They are held together with special screws and metal plates attached to the outer surface of the bone.
Plates and screws are often used when intramedullary nailing may not be possible, such as for fractures that extend into either the hip or knee joints.
Most femoral shaft fractures take 4 to 6 months to completely heal. Some take even longer, especially if the fracture was open or broken into several pieces.
Many doctors encourage leg motion early in the recovery period. It is very important to follow Dr. Backe’s instructions for putting weight on your injured leg to avoid problems.
In some cases, doctors will allow patients to put as much weight as possible on the leg right after surgery. However, you may not be able to put full weight on your leg until the fracture has started to heal. It is very important to follow Dr. Backe’s instructions carefully.
When you begin walking, you will most likely need to use crutches or a walker for support.
Because you will most likely lose muscle strength in the injured area, exercises during the healing process are important. Physical therapy will help to restore normal muscle strength, joint motion, and flexibility.
A physical therapist will most likely begin teaching you specific exercises while you are still in the hospital. The therapist will also help you learn how to use crutches or a walker.
