Relations. — In the proximal half of the leg the extensor digitorum longus lies lateral to it; 

 and between the two muscles, the anterior tibial artery and vein. It is covered by the crural 

 fascia and rests on the interosseous membrane. Distally it lies over the extensor hallucis 

 longus. The tendon passes in special compartments beneath the transverse and the cruciate 

 (anterior annular) ligaments.
