A diagnosis of Morton’s neuroma is typically made by listening to your symptoms and an examination of the affected foot. On some occasions a medical professional will be able to feel the neuroma, and the area around it may be tender.
Diagnosis by Mulder’s Sign
One physical examination that is often carried out to diagnose and Morton’s neuroma, is something called a Mulder’s Sign or a Mulder’s click. This simple test includes squeezing the metatarsals together with one hand in order to reproduce pain, or a click. A positive Mulder’s sign is indicative of the presence of a Morton’s neuroma.
Diagnosis by Medical Imaging
Another form of diagnosis is the use medical imaging. Neuromas can be visualised on MRI and Ultrasound scans. Here at The Barn Clinic, we prefer to use Ultrasound imaging, as we can scan, move and manipulate the foot in order to locate a neuroma. Sometimes when MRI is used, neuromas can occasionally be missed, as the scan rely in the foot being in a very precise position, and the patient remaining perfectly still. It is for this reason we carry out all our own medical imaging to locate, measure and diagnose Morton’s neuroma.
