Calf muscle duplication
The
accessory soleus muscle
is an
accessory muscle
of the calf which is rarely present in humans;
[1]
it is, however, the most common accessory muscle of the
ankle
.
[2]
The muscle inserts on the anterior aspect of the
soleus muscle
or on the posterior aspect of the
tibia
or the muscles of the deep posterior compartment. It lies anterior to the
calcaneal tendon
and terminates on the calcaneal tendon or the superior or medial aspect of the calcaneus via fleshy fibers or a distinct
tendon
.
[3]
Present in approximately 3% (or 10%)
[4]
of people, this muscle usually appears as a distant belly, medial to the
Achilles tendon
. Clinically, the accessory soleus may be associated with pain and edema during periods of prolonged exercise.
