Ultrasound-Guided Percutaneous Needle Electrolysis in Dancers with Chronic Soleus Injury: A Randomized Clinical Trial

Figure 2

PNE intervention in soleus muscle injury. (a) Ultrasound-guided invasive approach of the soleus muscle; (b) ultrasound-guided percutaneous needle electrolysis procedure; (c) normal ultrasound image of the soleus muscle (transverse axis); and (d) ultrasound image of the injured central tendon of the soleus muscle (transverse axis). Ultrasound imaging shows muscle fiber disorganization at the level of tear (arrowhead). CT: central tendon.
