Medial impingement of the ankle in athletes
1Michigan International Foot and Ankle Center, Pontiac, Michigan ; Orthopaedic Surgery, Wayne State University, Detroit, Michigan ; Michigan State University, East Lansing, Michigan.
Context:
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.

Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
