What is Morton's Neuroma and what are its symptoms?
Morton's Neuroma is a form of perineural fibrosis that is caused by prolonged pressure or repetitive strain on the foot. Despite the term “neuroma,” it is not a tumor but rather a benign thickening of the nerve due to chronic compression or irritation. The condition is more common in women and is often associated with wearing tight or high-heeled footwear. Morton's Neuroma typically causes the following symptoms:
- Pain radiating to the toes
- Burning or numbness in the front part of the sole
- A sensation similar to having a foreign object inside the shoe
- Worsening of symptoms while walking
What is the role of Ultrasound in treating Morton's Neuroma?
Diagnosis of Morton's Neuroma can be based on clinical examination and confirmed through a Foot Ultrasound, which enables accurate imaging of the enlarged nerve area.
Ultrasound-Guided Injectable Corticosteroid Treatment is an effective, minimally invasive option for Morton's Neuroma. Thanks to Ultrasound Guidance, the anti-inflammatory medication is injected precisely at the site of the neuroma, reducing its size, relieving symptoms, and improving foot mobility.
Injectable Corticosteroid Treatment is recommended for patients who have not responded to conservative measures such as specialized footwear and exercises, as well as for those who wish to delay or avoid surgical intervention. The treatment is performed under local anesthesia and takes approximately 30 minutes.
Why is Ultrasound Guidance important during Injectable Treatment for Morton's Neuroma?
The accuracy in needle placement provided by Ultrasound Guidance is critical both for the success of the treatment and for avoiding potential complications. In the case of Morton's Neuroma specifically, one of the most important structures to avoid during injection is the plantar plate, a fibrous formation at the base of the metatarsals. If the corticosteroid is injected into the plantar plate, there is a risk of rupture and the development of arthropathy.
Thanks to Ultrasound Guidance, a specialized Radiologist can precisely identify the nerve and ensure that the injection is delivered to the appropriate location, minimizing the risk of adverse effects and enhancing the effectiveness of the treatment.
