Plantar Fibromatosis Treatment: From Observation to Surgery

Plantar fibromatosis (Ledderhose disease) is a benign fibroproliferative condition causing nodular thickening of the plantar fascia. Unlike plantar fasciitis, the nodules in plantar fibromatosis do not respond to stretching, cortisone, or standard fascia treatments — and the wrong treatment can worsen the fibrotic process. Management is driven by nodule size, symptoms, and rate of progression.

Treatment Options by Evidence and Stage

Treatment	Mechanism	Evidence Level	Best Indication	Key Limitation
Observation / offloading orthotics	Custom insole with nodule relief cavity; pressure redistribution	Expert consensus — standard first step	Small asymptomatic or mildly symptomatic nodules	Does not reduce nodule size; symptomatic management only
Topical verapamil 15% gel	Calcium channel blocker inhibits fibroblast proliferation and collagen synthesis	Moderate — several studies show nodule softening and size reduction	Small to medium nodules; early disease	Requires compounding pharmacy; 3-6 month course; partial response
Collagenase injection (Xiaflex/CCH)	Enzymatic degradation of excess collagen in nodule	Moderate — promising case series; not FDA-approved for plantar fibromatosis	Nodules with high collagen content; off-label use	Off-label; technique-sensitive; risk of tendon injury
Radiotherapy (low-dose)	Inhibits fibroblast proliferation; induces apoptosis in fibrotic tissue	Moderate-high — best evidence for disease stabilization in early stage	Progressive disease; early stage; avoid in young patients	Radiation exposure; not universally available; not curative
Corticosteroid injection	Anti-inflammatory; may temporarily soften nodule	Low — poor long-term evidence; may accelerate fibromatosis in some cases	Acute pain flare management only	Risk of fat pad atrophy; plantar fascia rupture; avoid repeated injections
Surgical excision	Removal of nodule(s) and involved fascia	Moderate — effective but high recurrence rate (25-50% at 5 years)	Large painful nodules; failed all conservative options; functional impairment	Significant recurrence; wound healing complications; sensory nerve injury risk

Surgical Extent and Recurrence Risk

Surgical Extent	Recurrence Rate	Complication Risk	Indication
Local nodule excision only	50-65% recurrence — highest	Low	Rarely recommended — insufficient
Wide local excision (fascia margin)	25-35% recurrence	Moderate — wound dehiscence, nerve injury	Standard surgical approach
Total plantar fasciotomy / fasciectomy	Less than 15% recurrence	High — foot instability, flat arch, sensory loss	Severe diffuse disease; last resort

The association of plantar fibromatosis with Dupuytren contracture (palmar fibromatosis) and Peyronie disease (penile fibrosis) is well established — these three conditions share the same fibroproliferative pathology. Patients with one fibromatosis condition should be screened for the others. Diabetes, alcoholism, and epilepsy medications are systemic risk factors.

At Balance Foot & Ankle in Howell and Bloomfield Township, we evaluate plantar nodules with ultrasound to confirm fibromatosis and stage disease for conservative or surgical management. Call (810) 206-1402.
