Morton's Neuroma Treatment Options
Radiofrequency Nerve Ablation
Radiofrequency nerve ablation is a minimally invasive ultrasound guided procedure that uses high frequency radio waves to heat the neuroma. It is usually performed at a temperature of 90 degrees Celsius. At this temperature the neuroma is denervated and is thus no longer able to transmit pain signals. Radiofrequency nerve ablation is a recognised treatment for various foot conditions and has been used in medicine for many years, mostly for chronic back pain and heart disorders. The results of nerve ablation are comparable to open surgery (neurectomy) but come with less risks and faster recovery.
Corticosteroid injections are a common treatment for Morton's neuroma. The aim of a corticosteroid injection is to reduce inflammation, nerve thickening and pain. They are often effective in the short term (< 3 months) but less effective in the longer term for most patients. It is possible to have mutiple corticosteroid injections as and when required to manage the pain however this may increase the risk of unwanted side effects including thinning of the plantar fat pad and lesser toe deformities.
Orthotics are special insoles that are added to shoes to reduce pressure on/around the nerve. This helps prevent repetitive irritation of the nerve which reduces pain frequency and intensity. This can make the condition manageable in the long term and allow patients to continue their day to day activities. Sometimes orthotics aren't effective at reducing pain levels. This can happen if the neuroma is particularly large. In this scenario mosty patients go on to receive other treatment.
Neurectomy involves surgical removal of the nerve via open surgery. This procedure is recommended when conservative treatments have not worked. The results of neurectomy are generally very good with overall success rates around 80 85%. The main post-op complication of neurectomy surgery is a stump neuroma. This is a painful end of the nerve where the nerve has been cut surgically. The incidence of stump neuroma is approximately 15%.
