Extensor Digitorum Longus (EDL) Anatomy
This muscle is present on the outer front of the lower leg. The name though sounds difficult but clearly defines the muscle. Extensor= muscle that extends, Digitorm= the digits of the foot (the small toes) and longus= because it is relatively longer than the other extensor of the digits.
It is present in the anterior compartment of lower leg and originates from both the lower leg bones tibia and fibula.
It arises from the upper end of tibia (lateral condyle), from the upper end and front surface of fibula and also from the membrane present between both these bones.
