What is Plantar Fibroma?
Plantar fibromas are growths that develop in the arch of the foot (on the plantar fascia), which is the band of tissue that spans the bottom of your foot. Fortunately, these growths are non-cancerous and therefore pose little threat, but can, however, cause pain or discomfort when walking or standing for long periods of time.
Causes and Symptoms of Plantar Fibroma:
The exact causes of Plantar Fibromas is not known, but many experts conclude that they begin with a small tear in your plantar fascia from a specific trauma to the affected area. The theory is that these bumps found in the arch of the foot are a result of scare tissue formed from the body attempting to heal the tears.
The biggest tell-tale sign of a Plantar Fibroma is a visibly noticeable, firm bump found on the arch of the foot. It may change in size or stay the same over time and they can arrive singularly or in groups. It’s also important to be aware that a Plantar Fibroma may or may not come with pain. Typically, pain is felt with a Plantar Fibroma when a shoe pushes it against it.
Diagnosis for a Plantar Fibroma:
In working to diagnose a plantar fibroma, your trusted orthopaedic surgeon will do a physical examination of the foot by pressing on the affected area. This can produce pain that radiates to the toes. An MRI scan or soft tissue biopsy may be performed to further assess the lump and aid in diagnosis.
Treatment for Plantar Fibroma:
Plantar Fibroma treatment options may include physical therapy, orthotic devices, corticosteroid injections, and in more severe instances, surgery to remove the growth. Steroid injections are often used to shrink the mass and further relieve any pain occurring when walking, however this route could be temporary, and the fibroma could return. Orthotic devices are used when the fibroma is stable and not changing in size. Custom shoe inserts may be a conservative way to relieve pain by better distributing the patient’s weight. Physical therapy is one of least invasive ways to curtail pain, especially when coupled with anti-inflammatory medications.
If surgery is recommended to you to best treat your condition, it’s important to know that removing a plantar fibroma can result in the flattening of the arch or the development of hammertoes. Your foot and ankle specialist or trusted orthopaedic doctor will be able to best diagnose your condition and develop a treatment plan appropriate for you.
