What Is Plantar Fibromatosis?
Plantar fibromatosis is a condition where firm, nodular masses called plantar fibromas form within the plantar fascia, the strong ligament that runs along the arch of the foot. These growths are benign (non-cancerous) and may appear as a single lump or in clusters. As they slowly enlarge, they often press against shoes and the ground, leading to pain with walking.
What Causes Plantar Fibromas?
An exact cause cannot always be identified, but several factors are linked to their development:
- Damage or repeated strain to the plantar fascia ligament
- Use of the medication Dilantin
- A genetic tendency toward similar fibrous growths
About 10% of patients with plantar fibromas also develop comparable lumps in the palms, a condition known as Dupuytren’s Contracture.
How Plantar Fibromatosis Is Diagnosed
Diagnosis is typically made through a careful clinical exam. Biopsy is generally avoided because the procedure itself can cause the fibroma to enlarge. If a mass is surgically removed, a pathologist confirms the diagnosis through microscopic examination of the tissue.
Treatment Options
Most cases respond well to conservative care that takes pressure off the nodule and the surrounding ligament:
- Padding and shoe modifications to reduce direct pressure on the lump
- Custom functional foot orthotics to relieve strain on the plantar fascia, which can sometimes help the fibroma shrink
- MLS laser therapy, an FDA-cleared, non-invasive option used to help reduce pain and inflammation in soft-tissue conditions
- Surgical excision when the mass remains painful or continues to enlarge
Surgery typically involves removing most of the plantar fascia along with the mass, since simply removing the lump alone often leads to recurrence. After surgery, wearing a custom orthotic is recommended to support the foot and accommodate the loss of the ligament.
