What Causes a Plantar Fibroma?

Plantar fibromas are a relatively uncommon, but often painful, condition that affects the feet. These benign growths, typically found in the arch of the foot, develop within the plantar fascia, the band of tissue that connects the heel bone to the toes. The exact cause of plantar fibromas is not well understood, but they are believed to be related to genetics and may develop due to overuse or trauma to the foot. The primary symptom of plantar fibromas is a noticeable lump or nodule in the arch of the foot. This lump is often painful and can make walking and standing uncomfortable. In some cases, it may restrict foot movement. Treatment options vary depending on the severity of symptoms. Conservative approaches include wearing orthotics or making shoe modifications that may help to alleviate pressure on the lump. In more severe cases, corticosteroid injections or surgical removal may be necessary to relieve pain and restore foot function. Early intervention can help to manage the condition effectively and improve overall foot health. If you suspect you have a plantar fibroma, it is suggested that you consult a podiatrist for a proper diagnosis and personalized treatment plan.

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.
