What is Ankle Impingement?

Impingement of the ankle refers to pinching or nipping of soft tissues around the ankle.  This can occur either in the front of the ankle (anterior) or in the back (posterior).  Anterior impingement is most commonly associated with an old ankle sprain that either did not heal properly or was not completely rehabilitated, while posterior impingement is more common in ballet dancers or in people with excessive bone growth in the area.

Symptoms of ankle impingement can include pain in the front of the ankle or to the side of the ankle that continues after a sprain, or weakness in the ankle during activities.  The pain may be worsened when the foot is forced upwards into dorsiflexion.  There may even be inflammation or thickening of the tissue in the anterior portion of the ankle. 

Symptoms of posterior impingement will include pain that feels deep in the back of the ankle, made worse when the toes are pointed downwards into plantarflexion.  There may even be a painful clicking sensation associated with movement of the foot or ankle. 

Non-surgical treatment is used first to help alleviate symptoms of ankle impingement.  A short-leg cast or a walking boot may be used to limit motion around the ankle for up to four weeks.  This limitation in movement can help reduce the pain.  Additionally, ice can be applied to area to reduce any inflammation that may be present, and non-steroidal anti-inflammatory medications may be used as well.  Physical therapy is often prescribed for impingement as well.  This may include a gradual return to full activity through different exercise modalities. 

If non-surgical intervention does not help relieve pain, surgery may be necessary to reduce some of the inflamed tissue and help prevent impingement.  Each case is different, and a foot and ankle surgeon should be consulted to evaluate the patient’s condition. 

Following surgical intervention, a period of rehabilitation with a physical therapist may also be necessary to regain strength and function of the ankle.  The use of orthotics is common following this type of surgery, as they may help prevent any further damage or recurrence.  Any additional problems such as tendinitis, ankle arthritis, or other foot and ankle condition may be treated at the same time. 

If left untreated, ankle impingement can lead to formation of bone around the ankle.  These bone spurs can cause further impingement, thus making the problem worse and leading to more pain.
