MICHIGAN PODIATRIST INSIGHT
Balance Foot & Ankle offers same-day appointments for urgent foot and ankle conditions across Southeast Michigan — but the most important factor in outcomes isn’t getting seen quickly. Our podiatrists explain what to do in the first 24-48 hours before your appointment that most patients skip entirely. Call (810) 206-1402 — expert podiatric care across Michigan.
Dr. Biernacki explains plantar fibroma diagnosis, conservative treatment, and surgical considerations.
What Is a Plantar Fibroma?
A plantar fibroma is a benign fibrous tumor arising from the plantar fascia in the medial longitudinal arch. Unlike a plantar wart (which involves the skin) or a ganglion cyst (fluid-filled), a plantar fibroma is a solid, firm, immovable nodule embedded within the fascia itself. Most are 1–3 cm in size and cause pain from direct pressure against the plantar surface with weight-bearing. Plantar fibromatosis — the multi-nodular, progressive form — represents a more aggressive proliferative condition analogous to Dupuytren’s contracture in the hand.
Who Gets Plantar Fibromas?
Plantar fibromas are most common in middle-aged adults, with a slight male predominance. Risk factors include a family history of fibromatous conditions (Dupuytren’s contracture, Peyronie’s disease), diabetes, epilepsy (particularly phenytoin use), alcohol-related liver disease, and thyroid disease. There is no clear link to repetitive trauma or athletic activity. Some cases develop spontaneously without identifiable risk factors.
Diagnosis: Clinical Exam and MRI
Diagnosis is straightforward clinically — a firm, immovable nodule in the medial arch that does not transilluminate (unlike a cyst) and is attached to the plantar fascia on palpation. MRI confirms the diagnosis and delineates the fibroma’s extent within the fascia — critical for surgical planning. MRI appearance (low T1/T2 signal due to fibrous tissue) is characteristic of fibroma and helps exclude more concerning lesions. Ultrasound can confirm the solid, hypoechoic nature of the nodule in equivocal cases.
Conservative Treatment
First-line treatment focuses on offloading the fibroma. A custom orthotic with a cutout beneath the nodule dramatically reduces plantar pressure on the mass and significantly improves walking comfort. Corticosteroid injection into the fibroma can reduce its size and tenderness — though not eliminate it — and provide months of relief. Topical verapamil gel (15% compounded) applied twice daily for 3–6 months has been shown in small studies to reduce fibroma size, though evidence remains limited. These conservative measures manage the majority of patients successfully without surgery.
Surgical Excision: Indications and Recurrence Risk
Surgical excision is reserved for fibromas that are rapidly enlarging, causing significant disability despite conservative care, or multiple with progressive fibromatosis causing toe contracture. The critical surgical principle is wide local excision — the fibroma must be excised with a generous margin of surrounding fascia to reduce recurrence risk. Even with wide excision, recurrence rates of 50–60% are reported in the literature. Partial excision (removing only the nodule) carries near-100% recurrence. Dr. Biernacki counsels patients extensively on recurrence risk before recommending surgery and ensures that conservative options have been genuinely exhausted.
Dr. Tom's Product Recommendations
Tuli’s Heavy Duty Heel Cups with Arch Support
⭐ Highly Rated
Therapeutic heel cup and arch support that can be used with a custom cutout modification to offload plantar fibroma nodules — reducing direct pressure during weight-bearing.
Dr. Tom says:“Compressible gel construction conforms to foot contours and can be modified with cutout to entirely offload the fibroma — the cornerstone of conservative management.”
✅ Best for Plantar fibroma offloading and arch pain relief
⚠️ Not ideal for OTC option — custom orthotics with professional cutout provide superior offloading
MRI confirms benign diagnosis and delineates extent for precise surgical planning.
Wide local excision (when indicated) achieves lowest possible recurrence rate.
❌ Cons / Risks
50–60% recurrence rate even with wide local excision — surgery is not curative.
Verapamil gel evidence remains limited — not FDA-approved for this indication.
Multiple fibromas (fibromatosis) carry higher recurrence and progression risk.

Dr. Tom Biernacki’s Recommendation
Patients with plantar fibromas are often frightened — a firm lump in their arch makes them think the worst. The MRI quickly confirms it’s benign fibrous tissue, not anything sinister. Then I tell them: let’s not rush to surgery. The recurrence rate is high, and a good orthotic with a cutout often makes the pain tolerable for years. Surgery when nothing else works — not as a first response.

Frequently Asked Questions
Is a plantar fibroma dangerous?
No — plantar fibromas are benign. They do not become malignant. The concern is pain and functional limitation, not cancer risk. MRI confirms the benign fibrous nature and excludes rare soft tissue tumors that can present similarly.
Will a plantar fibroma go away on its own?
Plantar fibromas rarely resolve spontaneously. They may stabilize in size or slowly enlarge. Conservative treatment manages symptoms; only surgical excision removes the mass, though with significant recurrence risk.
Can cortisone injections shrink a plantar fibroma?
Corticosteroid injections can reduce fibroma size (by 20–30% in some studies) and significantly reduce pain and tenderness. They do not eliminate the fibroma but can provide meaningful relief for many months.
What is Ledderhose disease?
Ledderhose disease is plantar fibromatosis — the development of multiple fibrous nodules in the plantar fascia with progressive contracture. It is the foot equivalent of Dupuytren’s contracture (hand) and Peyronie’s disease. It has a stronger hereditary component and is more challenging to manage surgically.
In-Office Treatment at Balance Foot & Ankle
If home treatment isn’t providing relief for your plantar fasciitis, our podiatry team at Balance Foot & Ankle can help with same-day evaluations and advanced in-office care.
Frequently Asked Questions
When should I see a podiatrist?
If symptoms persist past 2 weeks, affect your normal activity, or are accompanied by red-flag symptoms (warmth, redness, swelling, inability to bear weight).
What does treatment cost?
Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Out-of-pocket costs vary by your specific plan.
How quickly can I get an appointment?
Most non-urgent cases see us within 5 business days. Urgent cases (sudden pain, possible fracture) typically same or next business day.
