Peroneal tendinitis or tears affect the lateral border of the ankle and foot. Mild cases may be notable only for pain and swelling along the tendon, while more severe cases lead to difficulty with balance and ambulating uneven surfaces.
The peroneal tendons are the major evertors of the foot, which assist with side-to-side motion of the foot. Therefore, when it is weak or injured, balance can become difficult, especially when walking on banked or uneven surfaces.
Risk factors for this condition include:
- overuse
- distance running
- high arches
- cutting sports such as basketball, tennis, or soccer
- obesity
- diabetes
- hypertension
- prior trauma or surgery
- inflammatory arthritis.
Diagnosis
The first step in diagnosis is appropriate imaging (weight-bearing x-rays of the foot and ankle) and a thorough physical examination. If there is suspicion for a tear of the peroneal tendons, an MRI will be ordered.
