A Plantar fibroma is a benign growth that develops on the plantar fascia, the thick band of tissue that runs along the bottom of the foot, connecting the heel to the toes. This condition typically presents as a firm nodule or lump in the arch or ball of the foot, causing discomfort and pain with weight-bearing activities. The exact cause of plantar fibromas remains uncertain, but factors such as trauma, inflammation, or genetic predisposition may contribute to their development. Plantar fibromas can vary in size and may gradually increase in size over time, potentially interfering with normal foot function and mobility. While plantar fibromas are non-cancerous and generally harmless, they can cause significant discomfort and impact daily activities if left untreated. In some cases, surgical intervention may be necessary to remove the fibroma and restore foot function. If you have noticed a lump or nodule on the bottom of your foot, it is suggested that you schedule an appointment with a podiatrist who can diagnose and treat a plantar fibroma or whatever else might be going on.

A plantar fibroma may disrupt your daily activities. If you have any concerns, contact one of our podiatrists of Bruening Foot & Ankle. Our doctors can provide the care you need to keep you pain-free and on your feet.

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.
