What Is A Calcaneous Fracture?

A fracture of the calcaneus, or heel bone, can be a painful and disabling injury. This type of fracture commonly occurs during a high-energy event—such as a car crash or a fall from a ladder—when the heel is crushed under the weight of the body. When this occurs, the heel can widen, shorten, and become deformed.

Calcaneus fractures can be quite severe. Treatment often involves surgery to reconstruct the normal anatomy of the heel and restore mobility so that patients can return to normal activity. But even with appropriate treatment, some fractures may result in long-term complications, such as pain, swelling, loss of motion, and arthritis.

Calcaneus fractures are uncommon. Fractures of the tarsal bones account for only about 2% of all adult fractures and only half of tarsal fractures are calcaneus fractures.

A fracture may cause the heel bone to widen and shorten. In some cases, a fracture may also enter the subtalar joint in the foot. When this occurs, damage to the articular cartilage covering the joint may cause long-term complications such as chronic pain, arthritis, and loss of motion.

When the bone breaks and fragments stick out through the skin or if a wound penetrates down to the bone, the fracture is called an “open” fracture. An open fracture often causes more damage to the surrounding muscles, tendons, and ligaments and takes a longer time to heal. Open fractures have a higher risk for infection in both the wound and the bone. Immediate treatment to clean the wound is required to prevent infection.

What Are The Symptoms of A Calcaneous Fracture?

Patients with calcaneus fractures usually experience:

• Pain
• Bruising
• Swelling
• Heel Deformity
• Inability to put weight on heel or walk

With some minor calcaneus fractures, the pain may not be enough to prevent you from walking — but you may limp. This is because your Achilles tendon acts through the calcaneus to support your body weight. If, however, your calcaneus is deformed by the injury, your muscle and tendon cannot generate enough power to support your weight. Your foot and ankle will feel unstable, and you will walk differently.

What Causes A Calcaenous Fracture?

The calcaneus is most often fractured during a:

• Fall from a height
• Twist injury to the ankle
• Motor vehicle collision

The severity of a fracture can vary. For example, a simple twist of the ankle may result in a single crack in the bone. The force of a head-on car collision, however, may result in the bone being shattered (comminuted fracture).

Similar fractures can result from different mechanisms. For example, if you land on your feet from a fall, your body’s weight is directed downward. This drives the talus bone directly into the calcaneus. In a motor vehicle crash, the calcaneus is driven up against the talus if the heel is crushed against the floorboard. In both cases, the fracture patterns are similar. As a rule, the greater the impact, the more the calcaneus is damaged.

In a high-energy fracture, other injuries, such as fractures of the spine, hip, or other heel, can occur.

bones in place, the bones themselves can sometimes fracture and disintegrate – without the patient feeling any pain. This may result in a severely deformed foot that is very challenging to correct with surgery. Special shoes or braces are the best method for dealing with this problem.

What Are The Treatment Options For A Calcenous Fracture?

Your doctor will consider several factors in planning your treatment, including:

• The cause of your injury
• Your overall health
• The severity of your injury
• The extent of soft tissue damage

Because most calcaneus fractures cause the bone to widen and shorten, the goal of treatment is to restore the normal anatomy of the heel. In general, patients whose normal heel anatomy is restored have better outcomes. In most cases, recreating the normal heel anatomy involves surgery. Your doctor will discuss the different treatment options with you.

Nonsurgical Treatment

Nonsurgical treatment may be recommended if the pieces of broken bone have not been displaced by the force of the injury.

Immobilization. A cast, splint, or brace will hold the bones in your foot in proper position while they heal. You may have to wear a cast for 6 to 8 weeks — or possibly longer. During this time, you will not be able to put any weight on your foot until the bone is completely healed.

Surgical Treatment

If the bones have shifted out of place (displaced), your doctor may recommend surgery.

Surgery to repair a calcaneus fracture can restore the normal shape of the bone but is sometimes associated with complications, such as wound healing problems, infection, and nerve damage. Nonsurgical treatment of some fractures, however, can also lead to long-term complications, such as pain, arthritis, and a limp. Your doctor will review the details of your injury and talk with you about the risks and benefits of surgical versus nonsurgical treatment.

Timing of surgery. If the skin around your fracture has not been broken, your doctor may recommend waiting until swelling has gone down before having surgery. Elevating your leg and keeping it immobilized for several days will decrease swelling. It will also give stretched skin a chance to recover. Waiting before the operation may improve your overall recovery from surgery and decrease your risk of infection.

Open fractures, however, expose the fracture site to the environment and must be treated immediately. They require surgery to clean the wound and remove damaged tissue

Early surgery is also often recommended for an avulsion fracture. Although uncommon, a piece of the calcaneus can be pulled off when the Achilles tendon splits away from the bone (avulsion). For this type of fracture, emergent surgery can decrease the risk of injury to the skin around the Achilles tendon.
