Isolated Rupture of the Distal Plantaris Muscle.

Abstract

In the present case, the plantaris tendon was ruptured in isolation and at the distal part of the tendon. An injury of the Achilles tendon, gastrocnemius muscle, or soleus muscle was not detected. To the best of our knowledge, a similar case has not yet been reported. Our case basically demonstrates that a rupture of the musculus plantaris does not have to occur at the myotendiouns junction or the muscle belly itself. The initial nonoperative treatment with physiotherapy, antiinflammatory medicine, and an early return to sports, even for this more distal plantaris tendon rupture, led to a good result.
