Plantar fibromatosis is a relatively rare, but often painful, condition that affects the plantar fascia, the thick band of tissue running along the bottom of the foot. Unlike more common foot problems, such as bunions or heel spurs, plantar fibromatosis is marked by the development of fibrous nodules or lumps within the plantar fascia. These nodules can vary in size and are typically firm to the touch. They often form in the arch of the foot but can appear in other areas as well. While the exact cause of plantar fibromatosis remains unclear, it's thought to be related to genetic factors and may also be influenced by trauma or injury to the foot. The condition is typically benign but can be quite painful, affecting one's ability to walk and engage in regular activities. Understanding plantar fibromatosis is important for early diagnosis and appropriate care, as it can help individuals find relief from this challenging foot condition. If you have developed this ailment, it is suggested that you confer with a podiatrist who can confirm the diagnosis and offer appropriate relief and treatment methods.

Plantar Fibroma

A plantar fibroma is a fibrous knot in the arch of the foot. It is embedded in the plantar fascia which is a band of tissue that extends from the heel to the toes along the bottom of the foot. There can be multiple plantar fibromas in the feet at the same time. There are no known causes for this condition. If you have a plantar fibroma, there will be a bump in the arch of your foot that cannot be missed. Any associated pain is most often due to a shoe rubbing against the nodule. Non-surgical options, such as steroid injections, physical therapy, and orthotics should be tried first. Surgery is a last resort and is the only thing that will remove a plantar fibroma entirely. Consult with a podiatrist for a proper diagnosis and to determine the treatment regimen that is right for you.

What Causes a Plantar Fibroma?

While there are no specific causes identified, a plantar fibroma can possibly come from genetic predisposition or the formation of scar tissue that forms from healing the tears in the plantar fascia.

What Are the Symptoms of a Plantar Fibroma?

There will be a noticeable lump in the arch of the foot that may or may not cause pain. If pain is felt, it is typically because a shoe is rubbing up against the lump or when walking or standing barefoot.

Treatment and Prevention

A plantar fibroma will not disappear without treatment, but it can get smaller and be a non-issue. If pain persists, a podiatrist examines the foot and when the arch of the foot is pressed, pain can be felt down to the toes. An MRI or biopsy might be performed to help diagnose or evaluate the plantar fibroma. The following non-surgical options are generally enough to reduce the size and pain of these nodules:

• Steroid injections
• Orthotics
• Physical therapy to help apply anti-inflammatory creams on the bump 

Surgery is considered if the mass increases in size and the patient continues to feel pain after non-surgical methods are tried.
