TREATMENT

Immediate first aid treatment for a talus fracture, as with any painful ankle injury, is to apply a well-padded splint around the back of the foot and leg from the toe to the upper calf to immobilize the limb and protect it. Elevating the foot above the level of the heart helps to minimize swelling and pain. Specific treatment depends upon the severity and the type of fracture, so it is important to seek immediate medical attention.

Nonsurgical Treatment

Only fractures that are well-aligned (stable) can be treated without surgery. This is very rare in a talus fracture, however, because of the high-energy force that causes the injury.

Casting. A cast will hold the bones in your foot in place while they heal. You will have to wear a cast for 6 to 8 weeks. During this time, you will be asked to limit the amount of pressure you put on your foot. The goal is for the bone to heal enough for you to bear weight on it without the risk that it will move out of position.

Rehabilitation. When the cast is removed, your doctor will give you exercises to help restore the range of motion and strengthen your foot and ankle.

Surgical Treatment

If the bones have shifted out of place (displaced), surgery to internally set and stabilize the broken pieces results in the best outcome and reduces the risk of future complications.

Open reduction and internal fixation. During this operation, the bone fragments are first repositioned (reduced) into their normal alignment. They are then held together with special screws or metal plates and screws.

Recovery

Bones have a remarkable capacity to heal. The more severe your injury, however, the longer your recovery may be. After surgery, your foot will be in a splint or cast from 2 to 8 weeks, depending on the nature of the injury and how well your doctor thinks it is healing. As your bones begin to heal, your doctor will likely order x-rays to ensure that everything is in alignment and healing properly.

Pain Management

After surgery, you will feel some pain. This is a natural part of the healing process. Your doctor and nurses will work to reduce your pain, which can help you recover from surgery faster.

Medications are often prescribed for short-term pain relief after surgery. Many types of medicines are available to help manage pain, including opioids, non-steroidal anti-inflammatory drugs (NSAIDs), and local anesthetics. Your doctor may use a combination of these medications to improve pain relief, as well as minimize the need for opioids.

Be aware that although opioids help relieve pain after surgery, they are a narcotic and can be addictive. Opioid dependency and overdose has become a critical public health issue in the U.S. It is important to use opioids only as directed by your doctor. As soon as your pain begins to improve, stop taking opioids. Talk to your doctor if your pain has not begun to improve within a few days of your surgery.

Early Motion

Many doctors encourage motion of the foot and ankle early in the recovery period, as soon as your pain allows. Patients who have had surgery are instructed to begin moving the affected area as soon as the wound heals. Patients who are treated without surgery will work on regaining motion in the foot and ankle after the cast is removed.

Physical Therapy

Specific physical therapy exercises can improve the range of motion in your foot and ankle, and strengthen supporting muscles.

Weight-bearing

When you begin walking, you may need to use a cane and wear a special boot. You will not be able to put all of your weight on your foot for up to two to three months. If you place too much weight on your foot too soon, the bone pieces may move out of place. Be sure to follow your surgeon’s directions. As your break heals and your pain improves, you will be allowed to put more pressure on your foot.

Complications After Talus Fractures

Avascular Necrosis (AVN)

With unstable talus fractures, the blood supply to the bone can be disrupted at the time of the injury. Sometimes, the blood supply simply returns to the bone and normal healing begins. In other cases, however, the bone cells die without a blood supply, leading to a gradual and very painful collapse of the bone. This condition is called avascular necrosis (AVN) or osteonecrosis with collapse.

When the bone collapses, the articular cartilage covering the bone also collapses. Without this smooth cartilage, bone rubs against bone, leading to increased pain, arthritis and loss of motion and function. The more severe the talus fracture, the more likely it is that AVN will occur. Even fractures that are treated appropriately, including those that are treated surgically, may develop AVN.

Posttraumatic Arthritis

Posttraumatic arthritis is a type of arthritis that develops after an injury. Even when your bones heal normally, the cartilage protecting the bones can be damaged, leading to pain and stiffness over time. The majority of talus fractures result in some degree of posttraumatic arthritis. In cases of extreme arthritis that limits activity, additional surgery, such as a joint fusion or ankle replacement, may be the best option to relieve symptoms.
