Cryotherapy for plantar fasciitis and nerve pain (Morton's neuroma)

What foot conditions does cryotherapy ablation treat? 

Cryotherapy ablation is one of the most effective treatment options for several painful medical conditions of the foot, including plantar fibroma, plantar fasciitis, heel spurs, and Morton’s neuroma. 

Ablation may be used for chronic back pain, as well as neck, shoulder, and knee pain.

How does cryotherapy work?

Cryoablation shrinks and destroys fibers in targeted peripheral nerves to reduce or stop the conduction and excitability of the nerve. A tiny ice ball on the end of the cryoprobe destroys damaged nerve fibers, blocking pain signals and allowing healthy sensory nerve regeneration.

In short: extremely cold temperatures destroy targeted nerves so they can no longer send pain signals to the brain. Through a rapid and limited deep-freezing of the affected area, the chronic pain caused by the nerve is resolved with a simple and comfortable office procedure. 

In the long term, cryotherapy nerve ablation can stop future irritation and inflammation of the nerve.

At University Foot & Ankle Institute, this ultrasound-guided non-surgical procedure is combined with a nerve stimulator to increase the accuracy of the probe placement and the success of the overall procedure.

What to expect during cryotherapy nerve ablation?

Cryosurgery is a minimally invasive and relatively painless modality. You may feel a slight pinch from the needle when the local anesthetic is injected, but after that, you shouldn’t feel much more than light pressure during the surgery. A small incision is made, and the cryoprobe is inserted into the foot. The procedure only takes a few minutes.

Sometimes the procedure does not fully treat the nerve pain on the first attempt, and a second or third treatment may be necessary.

Most patients find that after two or three treatments their pain is significantly less or completely gone. In the rare case that cryoablation has little effect after two or three months, we may need to use a different ultrasound-guided ablation procedure.

Another major upside to this procedure is we don’t “burn any bridges,” in other words, we can easily remove the damaged nerve if this procedure does not work. 

What to expect after cryotherapy ablation?

After cryotherapy ablation, it is normal to experience numbness, swelling, or bruising. Some people may also experience a tingling or “pins and needles” sensation. 

These side effects are usually temporary and should resolve within a few days. In very rare cases, more serious side effects may occur, such as nerve damage or skin injury. If you experience any of these side effects, please contact your doctor.

Are there risks with cryotherapy? 

Side effects are rare but can include short-term bruising, infection, or frostbite at the insertion area of the probe. You may also feel a small lump in your foot at the procedure site. This generally goes away within three to six months and does not cause pain.

Virtually all patients who have had cryoablation have maintained full motor function with no inappropriate loss of sensation. 

If patients are unlucky enough to experience a return of Morton’s neuroma symptoms, the cryoablation procedure can be repeated, or other non-surgical treatments can be used.

Cryotherapy FAQs

 

What type of sedation is used during nerve ablation?

Local anesthesia is the most common type of sedation for foot nerve ablation. The area around the nerve to be ablated is numbed with a local anesthetic, ensuring the patient feels no pain during the procedure. The patient remains awake and alert.

 

What happens if nerve ablation doesn't work? 

In some cases, a repeat ablation might be suggested. Some nerves can regenerate over time, or the initial ablation might not have fully encompassed the targeted nerve.

 

What is the success rate of cryotherapy for Morton's neuroma?

Research indicates that cryotherapy can significantly reduce pain for those suffering from Morton's neuroma. The success rates reported in various studies typically range between 70% and 90%. Patients often experience relief from pain and improvement in foot function after undergoing this treatment.
