Peroneal Tendon Injuries

 

Diagnosis
Because peroneal tendon injuries are sometimes misdiagnosed and may worsen without proper treatment, prompt evaluation by a foot and ankle surgeon is advised. To diagnose a peroneal tendon injury, the surgeon will examine the foot and look for pain, instability, swelling, warmth and weakness on the outer side of the ankle. In addition, imaging studies such as an MRI or ultrasound may be needed to fully evaluate the injury.
An ankle sprain may sometimes accompany a peroneal tendon injury. The surgeon is trained to look for signs of this and other related injuries. Proper diagnosis is important because prolonged discomfort after a simple sprain may be a sign of additional problems.

Treatment
Treatment depends on the type of peroneal tendon injury. Options include:

  • Immobilization. A cast or splint may be used to keep the foot and ankle from moving and allow the injury to heal. 
  • Medications. Oral or injected anti-inflammatory drugs may help relieve the pain and inflammation.
  • Physical therapy. Ice, heat or ultrasound therapy may be used to reduce swelling and pain. As symptoms improve, exercises can be added to strengthen the muscles and improve range of motion and balance.
  • Bracing. The surgeon may provide a brace to use for a short while or during activities requiring repetitive ankle motion. Bracing may also be an option when a patient is not a candidate for surgery.

Surgery. In some cases, surgery may be needed to repair the tendon or tendons and perhaps the supporting structures of the foot. The foot and ankle surgeon will determine the most appropriate procedure for the patient’s condition and lifestyle. After surgery, physical therapy is an important part of rehabilitation.
