What is an Ankle Fracture?

There are three distinct bones that join together to make up the ankle joint:  the tibia (the main bone in the lower leg), the fibula (the smaller bone that makes up the outside of the lower leg) and the talus (the ankle bone that forms the lower part of the joint).

Ankle fractures occur when one of these three bones break, fracture, or split. They occur when the ankle is severely twisted or rotate beyond the normal degree of motion. Severe trauma caused by force (such as a hard landing) can also fracture this joint.

What is the difference between an ankle sprain and an ankle fracture?

  • If only the ligaments are stretched or torn when the ankle joint sustains massive stress, then the result is a sprain.
  • If one of the bones in the joint breaks, it is a fracture. Fractures are broken bones, and can be either non-displaced (not out of the normal position) or displaced.

What are Ankle Fracture Symptoms?

The symptoms of an ankle fracture are pain and swelling almost immediately after the traumatic incident. Intense swelling, pain, and bruising often occurs swiftly after the injury has occurred.  The pain, depending on the degree of the fracture, will usually prevent a patient from walking or putting pressure of any kind on the joint. In more severe cases, a break or bone deformity can be seen through the skin. The surrounding nerves may be affected which may result in numbness and the inability to move the foot or toes.  If any or all of these symptoms are present, it’s important to seek medical care so that treatment can be applied quickly.

How to Know I Have a Broken Ankle

In almost all cases, an X-ray will be the initial method used to diagnose an ankle fracture. X-rays allow the bone to be viewed from various angles so that the severity of the break can be determined. In some cases, an MRI is used to evaluate the soft tissue structures of the ankle or a CT scan is needed to evaluate the bony structures in more detail.

Have you sustained an ankle fracture?

There are two ways to initiate a consultation with the sports foot & ankle group:

You can provide current X-rays and/or MRIs for a clinical case review ($250).

You can schedule an office consultation.

Does an Broken Ankle Require Surgery?

Ankle fractures occur along a continuum of injury.  Some are avulsions of bone which can be treated like a sprain and some require surgical intervention to realign the bones.  Our orthopaedic surgeons carefully evaluate each patient to determine fracture stability and optimal treatment.  If the fracture is minimally displaced and stable, non-operative treatment is usually recommended.  Non-operative treatment varies from CAM boot treatment to casting.  Physical therapy may be necessary after a period of immobilization and fracture healing.

What are the Surgical Treatment Options for a Fracture Ankle?

In complex cases involving displaced/unstable ankle fractures, surgery will be necessary to correct the injury. Surgical intervention involves making incisions on the ankle medially, laterally, or both to directly visualize the bone fragments and place them into anatomical alignment.  The bone fragments are then held in place using metal plates and screws.  An arthroscopic examination of the ankle cartilage may be recommended.  If arthroscopy is preformed, our surgeons can typically treat concomitant cartilage injury at the time of the initial surgery.

What is the Recovery Following Ankle Surgery?

Surgery for ankle fractures can be done as an outpatient procedure or involve a one-night stay depending on the severity of the injury.  We typically employ nerve blocks which can help control post-operative pain.  Weight bearing after surgery depends on the severity of the injury.  In severe fractures, weight bearing my not be allowed for up to eight weeks. Patients are treated with a splint or cast and transitioned to a walking boot prior to weight bearing.
