What side effects are associated with this type of intervention?

The most common treatments for Morton's Neuroma include corticosteroid injections, cryoablation, and surgical resection. Corticosteroid injections can provide short-term pain relief but have a long-term resolution rate of only 30% and may cause side effects such as pain at the injection site and potential weakening of the surrounding tissues. Cryoablation, which involves freezing the nerve tissue to reduce pain, has been shown to be safe and effective in small studies, with minimal side effects reported. Surgical resection has a higher success rate (51-85%) but carries risks of complications such as recurrent pain, numbness, loss of sensation, and the development of stump neuromas.

What prior FDA approvals exist?

Morton's Neuroma is commonly treated with conservative methods such as orthotics and steroid injections, which have limited long-term success rates. Surgical resection is another option but comes with a higher complication rate. Cryoablation, a technique that involves freezing nerve tissue to reduce pain, has shown promise in recent studies for treating Morton's Neuroma. However, there is no specific mention of FDA approvals for cryoablation in the provided context. The focus remains on its efficacy and safety as demonstrated in small studies, suggesting it as a potential alternative to more traditional treatments.

What other types of research exist?

Promising novel alternatives to cryoablation for Morton's Neuroma include ultrasound-guided percutaneous needle tenotomy, which involves fenestrating tendinotic tissue to promote healing, and iontophoresis, which uses electrical currents to deliver anti-inflammatory medications like dexamethasone. Both methods have shown potential benefits in preliminary studies and may offer effective pain relief.

Summary

This trial is testing cryoablation, a treatment that uses extreme cold to destroy nerve tissue, on middle-aged women with Morton's neuroma who haven't found relief from other treatments. The goal is to see if this method is more effective than steroid injections in reducing pain. Cryoablation is a specialized technique for providing long-term pain relief and has been used in various medical fields since its development in 1961.

Who is the study for?

This trial is for adults over 18 who have Morton's neuroma, a painful foot condition, and haven't improved after four weeks of non-surgical treatments like orthotics. Participants must be able to consent and complete surveys. Those with other foot issues on imaging or unable to follow the study plan can't join.

What is being tested?

The study compares two treatments for Morton's neuroma: cryoablation (freezing nerves) and steroid injections combined with lidocaine (a numbing agent). It aims to see which method better relieves pain in the short and long term after conservative methods fail.

What are the potential side effects?

Cryoablation may cause temporary discomfort, skin changes at the treatment site, or nerve damage. Steroid injections might lead to fat tissue thinning under the skin, color changes in the skin, increased blood sugar levels in diabetics, or tendon weakening.

Mechanism Of Action

Side Effect Profile

Prior Approvals

Other Research

Morton's Neuroma is commonly treated with cryoablation and corticosteroid injections. Cryoablation involves freezing the nerve tissue, which disrupts the nerve's ability to transmit pain signals, providing relief from the burning or shooting pain associated with the condition. This method is particularly relevant for patients who have not responded to conservative treatments like orthotics. Corticosteroid injections, on the other hand, reduce inflammation and swelling around the nerve, which can alleviate pain but often only provides short-term relief. Understanding these mechanisms is crucial for patients as it helps them make informed decisions about their treatment options, especially when considering the long-term efficacy and potential side effects.
