Peroneal Tendon Dislocation/Dysfunction

If you have ever experienced dislocation or dysfunction of a foot tendon, including the peroneal tendons, you know the pain such problems can cause. The two peroneal tendons, which run side-by-side behind the outer ankle bone, attach the outer ankle bone to the mid-foot bones while stabilizing the foot and ankle. The peroneal tendons are susceptible to strains, tears, dislocation, and inflammation, all of which can cause discomfort and other symptoms. When treated promptly, peroneal tendon problems are usually resolved. An experienced podiatrist can improve or restore the tendon’s functioning.

Causes of peroneal tendon dislocation/dysfunction

Common causes of peroneal tendon dysfunction or dislocation include: 

  • Activities involving repetitive foot movements. 
  • History of tendon inflammation (tendonitis). 
  • Previous peroneal tendon injuries.
  • Previous tendon dislocation. 
  • Sporting injuries.

Symptoms of peroneal tendon dislocation/dysfunction

Symptoms of peroneal tendon dislocation and dysfunction include: 

  • A snapping sound at the time of tendon injury. 
  • Changes in the height of the foot’s arch. 
  • Pain, swelling, and weakness or instability of the foot and/or ankle.

Treatment of peroneal tendon dislocation/dysfunction

Without treatment, a peroneal tendon dysfunction can cause changes in the shape of the arch and increase your risk of degenerative tears, dislocation, and rupture of the tendon. Therefore, it is important to seek treatment for a peroneal tendon dysfunction as soon as you notice symptoms.

Treatment options for a peroneal tendon dysfunction depend on the type and severity of dysfunction, and include:

  • Immobilizing the foot and ankle (i.e. with a cast or splint). 
  • Inflammation-reducing medications. 
  • Physical therapy.
  • Bracing the foot and ankle (i.e. with an orthopedic device). 
  • Surgery.

If you are experiencing the symptoms of a peroneal tendon dislocation or dysfunction, contact your doctor. An experienced podiatrist can provide the treatment you need.
