Ultrasound-guided technique with steroid injection for plantar fasciitisAs per a study that was presented at the annual meeting of the Radiological Society of North America (RSNA), the combination of an ultrasound-guided technique with steroid injection is 95 percent effective to relieve plantar fasciitis, a common and painful foot problem.

Luca M. Sconfienza, M.D., from Italy’s University of Genoa and lead author of the study, remarked that there is an absence of a widely accepted therapy when first-line treatments fail to relieve the pain of plantar fasciitis.

From News-Medical.Net:

For this study, Dr. Sconfienza and colleagues used a new ultrasound-guided technique, along with steroid injection, on 44 patients with plantar fasciitis that was unresponsive to conservative treatments.

After injection of a small amount of anesthesia, the anesthetic needle is used to repeatedly puncture the site where the patient feels the pain. This technique is known as dry-needling. Dry-needling creates a small amount of local bleeding that helps to heal the fasciitis. Lastly, a steroid is injected around the fascia to eliminate the inflammation and pain. The technique is performed with ultrasound guidance to improve accuracy and to avoid injecting the steroids directly into the plantar fascia, which could result in rupture.

After the 15-minute procedure, symptoms disappeared for 42 of the study’s 44 patients (95 percent) within three weeks.

Plantar fasciitis, the most common cause of heel pain, affects approximately one million people on a yearly basis in the United States alone.
