Medial impingement syndrome of the ankle is common in the athletic population. A marginal osteophyte on the leading edge of the medial talar facet and a corresponding “kissing” osteophyte on the tibia, in front of the medial malleolus, may abut and cause pain and limited dorsiflexion.
Background:
Palpation of the talar osteophyte and standard imaging—especially, the oblique view of the foot—are useful in making the diagnosis. Surgical removal of the osteophyte may be necessary.
Conclusions:
Ankle impingement is commonly seen in running and jumping sports, especially if the athlete has a subtle cavus foot. It may be associated with ankle instability, osteochondritis dissecans of the talus, and stress fractures of the foot.
