Ledderhose disease (plantar fibromatosis)

What is Ledderhose disease?

Ledderhose disease, medically known as plantar fibromatosis, is an increase in collagen-rich connective tissue in the plantar fascia. Tight knots or strands form that can cause discomfort when walking, standing, or under shoe pressure. The condition is related to Dupuytren's contracture of the hand and Peyronie's disease of the penis. It is not malignant, but can noticeably reduce the quality of life.

• Benign connective tissue changes in the plantar fascia
• Palpable, often painful knots/cords
• Commonly associated with Dupuytren's disease
• Variable course: stable, slowly progressive or relapse phases

Anatomy of the sole of the foot and what changes

The plantar fascia is a strong connective tissue strand that runs from the heel (heel bone) to the metatarsophalangeal joints of the toes. It stabilizes the longitudinal arch of the foot and transfers forces when rolling. In Ledderhose disease, sections of this fascia thicken due to overactive fibroblasts and increased collagen deposition.

• Location: usually medial in the longitudinal arch, 1–2 cm distal to the heel
• Consistency: coarse, difficult to move, often connected to the fascia
• Size: a few millimeters to several centimeters
• Skin: freely movable in early stages, later possibly adherent

Typical symptoms

The symptoms depend on the size, location and activity of the nodes. Some of those affected have hardly any symptoms, others suffer from stress-related pain and tenderness.

• Palpable knots or strands on the sole of the foot
• Pain when standing, walking or wearing tight shoes
• Morning start-up pain, especially a. after periods of rest
• Feeling of a “stone in your shoe”
• Rare: feeling of tension, pulling pain along the arch of the foot

Neurological deficits such as numbness or tingling are atypical and should suggest other causes.

Causes and risk factors

The exact cause has not been conclusively clarified. A combination of genetic predisposition, mechanical stimuli and metabolic factors is suspected. It is not a “self-inflicted” illness caused by exercise.

• Genetic disposition (frequent association with Dupuytren)
• Microtrauma and mechanical overload of the plantar fascia
• Diabetes mellitus, alcohol, smoking
• Epilepsy and long-term anticonvulsant therapy (associated, not causally proven)
• Men are more commonly affected, often starting in middle age
• Mutuality in a relevant proportion

What can you confuse Ledderhose disease with?

Not every lump on the sole of the foot is plantar fibromatosis. A careful assessment helps to avoid unnecessary worries and to choose the right therapy.

• Plantar fasciitis/heel spurs: predominantly heel pain without lumps
• Fat pad atrophy of the heel: load-dependent heel pain, no palpable fascial knot
• Ganglion/cyst or lipoma: usually softer, movable
• Epidermoid cyst, fibroma, rarely other soft tissue tumors
• Morton's neuroma: Pain in the forefoot between the metatarsals, not on the sole of the foot in the arch

Diagnosis: this is how we proceed

The diagnosis is often already clinically possible. Imaging is used for confirmation, assessment of spread and exclusion of other causes.

X-rays are only useful if accompanying bony findings (e.g. heel spurs) need to be clarified.

Conservative therapy: exhaust it first

The aim is to reduce pain, relieve pressure and maintain foot function. Knots usually cannot be “dissolved” conservatively, but symptoms can often be easily controlled.

• Shoe fitting: sufficient space in the forefoot and arch area, soft, cushioning soles
• Insoles with soft bedding and targeted recesses under the knot to relieve pressure
• Cushions and silicone pads for selective relief in everyday shoes
• Fascia-friendly stretching and mobilization exercises; Strengthening the short foot muscles
• Physiotherapy: manual techniques, sensorimotor training, gait analysis
• Activity control: prefer low-shock loads, avoid pressure peaks
• Medication: short-term anti-inflammatory painkillers (e.g. NSAIDs) as needed and tolerated
• Skin and scar care for irritated, tense skin over the lump

Important: Hard pressure massages directly on the knot are often counterproductive. Gentle mobilizations that do not additionally irritate the fascia are better.

Interventional options: consider carefully

If pain persists despite consistent basic therapy, selective procedures can be considered. Benefits and risks must be compared individually; a safe decline in nodes is not guaranteed.

• Shock wave therapy (ESWT): can reduce pain; Data for node shrinkage is limited.
• Corticosteroid injection into the node: may temporarily relieve discomfort; Risks include skin changes, fatty tissue atrophy and, in rare cases, fascia tears.
• Cryo- or needle fasciotomy/needling: isolated case reports, unclear long-term results; careful indication is required.
• Topical or intralesional substances (e.g. verapamil, collagenase): no confirmed standard indication; partly off-label with risks. Our advice is evidence-based and conservative.

Radiation therapy: special case in early stages

Low-dose radiation therapy can relieve pain and slow progression in early, active stages. The data is based predominantly on observational studies. A decision should be made in an experienced center and after careful risk-benefit assessment.

• Indication: early, painful, progressive nodules
• Goal: dampen inflammatory activity, slow progression
• Not for pregnant women; should be considered particularly carefully in young patients

Surgery: when does it make sense?

Surgery is usually only performed when conservative measures have been exhausted and the pain or functional limitations remain significant. The aim is to remove painful nodes while maximally protecting the foot architecture. A recurrence is possible; There is no guarantee that you will be free of symptoms over the long term.

• Procedure: local excision of individual nodes, partial or subtotal plantar fascia removal
• Recurrence rate: higher after pure nodule excision, lower after further fascia resection - but with potentially larger surgery
• Risks: Wound healing disorders, painful scars, skin sensitivity disorders (nerve branches), persistent pressure sensitivity
• Follow-up treatment: relief, gradual increase in load, insoles, scar management, physiotherapy

Careful preoperative imaging and planning of skin incisions are crucial to minimize complications and facilitate return to everyday life and work.

Rehabilitation and course

The healing process is individual. Many patients already benefit from shoe adjustments and insoles. Patience is important after operations as the sole of the foot is subjected to a lot of mechanical stress.

• Postoperatively: initially partial weight-bearing with suitable footwear, elevation, wound checks
• Pain relief: cooling, graduated pain management, later scar care
• Increase in stress: over weeks, in coordination with the findings and pain
• Return to sporting activities: depending on the procedure, often after 6-12 weeks, accompanied physiotherapy makes sense

Even without surgery, nodes can remain stable for a long time. Regular monitoring if symptoms change is advisable.

Everyday tips and self-help

• Choose shoes with soft, cushioning soles and enough volume in the arch area
• Consistently use inserts with a recess under the knot
• Daily, pain-adapted stretching exercises for the plantar fascia and calf muscles
• Prefer low-impact activities (cycling, swimming) and limit the amount of running you do
• Identify pressure points early and relieve them with padding
• Skin care of the sole of the foot, especially in diabetes, to avoid cracks
• Nicotine reduction, weight management and blood sugar control support tissue healing

When should you seek medical advice?

• New, hard lump on the sole of the foot
• Rapidly growing lesions or increasing pain
• Redness, overheating, skin changes or open areas
• Numbness, tingling, or radiating pain
• Diabetes with pressure sores on the soles of the feet

Warning signs such as pain at night when resting, very rapid growth or systemic symptoms are rare, but should be examined by an orthopedist in the short term.
