Extra articular hindfoot impingement syndrome

Case contributed by Dr Varun Babu


Chronic ankle pain

Patient Data

Age: 20 years
Gender: Female

MRI ankle

  • hind foot valgus (angle >20 degrees)
  • extra articular surface edema seen involving lateral talar process and calcaneal sulcus with areas of underlying sclerosis. 
  • decreased joint space involving lateral aspect of posterior talocalcaneal joint. 
  • minimal thickening of calcaneofibular ligament.
  • no calcaneofibular impingement. 
  • minimal ankle joint effusion and retrocalcaneal bursitis. 
  • normal sinus tarsi. 

Case Discussion

A hind foot valgus deformity may result in shift of weight bearing to the lateral half of the subtalar joint resulting in extra articular impingement of the talocalcaneum and eventually calcaneofibular impingement. The sinus tarsi is usually unaffected.
