The soleus is located in the superficial posterior compartment of the leg. It originates from the posterior surfaces of the head of the fibula and its upper third, as well as the middle third of the internal border of the tibia. Its other end forms a common tendon with the gastrocnemius muscle; this tendon is known as the calcaneal tendon or Achilles tendon and inserts onto the posterior surface of the calcaneus, or heel bone.
Mechanism of Injury
Repeated overuse of the muscle, eg. distance running, predisposes to a tear during push off in running or pivoting.
Pain is felt deep the calf and recurs on repeated loading.
Pain is triggered when the foot is plantar flexed against resistance eg. Normal walking, and usually aggravated more attempting to walk on tiptoes.
Bruising may become visible on the inner side of the proximal and middle parts of the shin about 24 hours after the initial injury.
Deep local tenderness is felt over the rupture, often along the soleus at the tibial margin.
Please consult with your medical professional for a complete diagnosis and treatment plan.
