Ultrasound Guided Steroid Injections

WHAT IS IT?

Ultrasound-guided steroid injections involve delivering a corticosteroid medication directly to an injury using real-time ultrasound imaging. At Feet First Clinic, these injections are commonly used to treat:

The goal is to reduce inflammation, relieve pain, and improve mobility.

HOW DOES IT WORK?

An ultrasound machine is used to visualize and “guide” the area being injected with a steroid. Steroid injections are anti-inflammatory medications that help reduce inflammation and pain. The medication reduces swelling, redness, and pain by calming the irritated tissues and nerves. Injecting the steroid directly in the affected area (underneath the plantar fascia) allows the medicine to go directly where it’s needed, so it works faster and with fewer side effects than pills.

By using an ultrasound machine to guide the injection, it ensures precision and that the steroid is delivered exactly where it is needed. It also minimizes risk of injecting into nerves, blood vessels, or fat pads, and is more effective compared to “blind” injections. The ultrasound also lets the chiropodist assess the area for things like thickened fascia, neuroma, or tendon changes.

Relief is typically felt within 7 days of the procedure. The pain relief often lasts weeks to months depending on the severity of the underlying condition and any contributing factors. Injections can be repeated after 4-6 weeks (maximum 3 injections in one year).

It’s important to note: While the procedure eases inflammation and its associated symptoms, it doesn’t fix the underlying cause. Stretching, supportive shoes, or orthotics may still be needed and will maximize the effectiveness of the procedure.

WHAT WILL HAPPEN?

At your first appointment, the chiropodist will perform a foot assessment with a full biomechanical and gait analysis in order to diagnose your foot condition, its underlying causes, and determine the best course of treatment. If you are diagnosed with plantar fasciitis and/or Morton’s neuroma, the chiropodist will then determine whether you are a candidate for ultrasound guided injections.

During the procedure, the chiropodist will use an ultrasound machine to visualize the affected area. They will then advance a fine needle under real-time ultrasound guidance to the target site and slowly deliver a corticosteroid, mixed with a local anaesthetic, to reduce inflammation. The ultrasound will help ensure the medication is injected at the proper speed.

This is a minimally invasive procedure performed in-clinic as an outpatient procedure. It can be repeated safely if needed.

RISKS & CONTRAINDICATIONS

While generally safe, possible risks include:

  • Temporary pain or soreness at the injection site
  • Bruising or mild swelling
  • Infection (rare)
  • Fat pad atrophy
  • Plantar fascia rupture (rare)
  • Nerve injury (rare, minimized with ultrasound guidance)
  • Temporary flare-up of symptoms (24–48 hours)

Ultrasound guided injections may not be suitable for people with the following:

  • Severe atrophy or thinning of the plantar fat pad
  • Partial tearing or severe degeneration of the plantar fascia
  • Recent steroid injections (typically you would want to wait 4-6 weeks before the next injection)
  • Steroid allergies
  • Bleeding disorders that are not medically controlled or patients on anticoagulants, as this can increase the risk of bleeding and bruising
  • Uncontrolled diabetes
  • Pregnancy
