Understanding Plantar Fibromas: Causes, Symptoms, and Treatment Options

front desk at Southern Maryland Foot and Ankle

A plantar fibroma is a benign growth that forms within the plantar fascia, the long band of tissue that runs along the bottom of your foot from your toes to your heel. Patients who visit Southern Maryland Foot & Ankle often report feeling a small lump beneath the skin in the arch of their foot. While the good news is that plantar fibromas are non-cancerous and may not cause pain initially, the bad news is that they will not resolve on their own. In fact, they often increase in size over time, potentially leading to discomfort during normal weight-bearing activities such as walking and running.

What Causes Plantar Fibromas?

The exact cause of plantar fibromas remains unclear. Some theories suggest that they may have a hereditary component, but more research is needed to confirm this connection. Factors that can contribute to the development of plantar fibromas include:

  • Genetics: A family history of plantar fibromas may increase your risk.
  • Foot mechanics: Abnormal foot mechanics and alignment can place undue stress on the plantar fascia.
  • Trauma: Previous injuries to the foot may play a role in the formation of these growths.

Symptoms of Plantar Fibromas

Patients with plantar fibromas typically notice the following symptoms:

  • Lump in the arch of the foot: A small, firm mass under the skin, often felt when walking or standing.
  • Discomfort or pain: While many individuals may not experience pain initially, discomfort can develop as the fibroma increases in size or when pressure is applied during weight-bearing activities.
  • Difficulty walking: As the condition progresses, the lump may interfere with normal foot function, leading to changes in walking patterns and additional foot pain.

Diagnosis of Plantar Fibromas

If you notice a lump in your foot, it’s essential to seek medical attention promptly. At Southern Maryland Foot & Ankle, our board-certified foot and ankle surgeon will perform a comprehensive evaluation to confirm a diagnosis of plantar fibroma. This process typically includes:

  1. Physical Examination: The doctor will examine your foot, focusing on the lump in the arch and assessing any pain or discomfort.
  2. Medical History: A thorough review of your medical history and any previous foot issues will help identify potential contributing factors.
  3. Imaging Studies: To rule out other conditions, such as cysts, ruptured tendons, nerve tumors, infections, or foreign objects, the doctor may order X-rays or other imaging studies.

Treatment Options for Plantar Fibromas

While plantar fibromas do not go away on their own, several non-invasive treatment options are available to manage symptoms and improve your quality of life. Treatment options include:

  • Anti-Inflammatory Medications: Over-the-counter or prescription medications can help reduce inflammation and relieve pain.
  • Steroid Injections: Corticosteroid injections may be administered to shrink the fibroma and alleviate discomfort in the affected area.
  • Physical Therapy: Targeted exercises and stretches can help improve foot mechanics and relieve pressure on the fibroma.
  • Orthotic Inserts: Custom orthotics can provide additional support, redistribute pressure, and reduce discomfort while walking.

While these treatments can help shrink the fibroma and alleviate symptoms, they may not eliminate the growth completely. If conservative measures fail to provide relief, the doctor may recommend surgical intervention to remove the fibroma.

Prevention Strategies

Since the underlying causes of plantar fibromas are not fully understood, specific prevention strategies are not currently available. However, maintaining optimal foot health can be beneficial. Here are some tips to help minimize the risk of developing plantar fibromas:

  • Wear Proper Footwear: Choose well-fitting shoes that provide adequate arch support and cushioning. Avoid high heels or shoes that place excessive pressure on the plantar fascia.
  • Maintain a Healthy Weight: Excess weight can put additional stress on your feet, increasing the risk of developing fibromas and other foot conditions.
  • Avoid Repetitive Stress: If your job or activities involve repetitive stress on the feet, take regular breaks and consider using supportive footwear.
