Studies have found that corticosteroid injection is a common treatment method for plantar fasciitis. The accuracy of drug injection is crucial to the treatment effect. Hormone drug injection into the fascia can make fascia brittle, thin, or calcified, even cause tearing. However, operating under shockwave can accurately observe the diffusion state of the drug and adjust the injection direction in real time, which not only reduces the dosage of the drug, but also greatly reduces the related complications.
