Short answer · Medically reviewed summary · Last updated: 2026-04-07
TL;DR: Treatment for Hereditary multiple exostoses (HME) is primarily focused on managing symptoms and monitoring for complications through regular clinical surveillance and orthopedic intervention. While there is no curative medication, surgical excision of exostoses is commonly performed to address pain, restricted range of motion, or nerve compression caused by the bony growths. What is the standard approach to managing Hereditary multiple exostoses? Because Hereditary multiple exostoses is a genetic condition characterized by the development of multiple benign bone tumors (osteochondromas), there is no single "best" treatment that applies to everyone.
3 people with Hereditary multiple exostoses have shared their first-person experience on this question at DiseaseMaps.
What are the best treatments for Hereditary multiple exostoses?
Treatments for Hereditary multiple exostoses: what real patients say works for them, alongside a medically reviewed overview citing sources like NIH GARD and Orphanet.

What is the standard approach to managing Hereditary multiple exostoses?
Because Hereditary multiple exostoses is a genetic condition characterized by the development of multiple benign bone tumors (osteochondromas), there is no single "best" treatment that applies to everyone. Instead, the management of Hereditary multiple exostoses is highly personalized based on the location and size of the exostoses. Clinical guidelines emphasize regular monitoring by orthopedic specialists to track growth and detect potential complications, such as limb-length discrepancies or joint deformities. In our DiseaseMaps community, 266 people with Hereditary multiple exostoses have shared that proactive monitoring remains the cornerstone of their long-term care plans.
What surgical and non-pharmacological interventions are available?
Surgery is the most frequent intervention for symptomatic Hereditary multiple exostoses. When an exostosis causes functional impairment, chronic pain, or neurovascular compression, surgical excision (removal) is often recommended. Other non-pharmacological treatments include:
- Physical therapy: Essential for maintaining joint mobility and strengthening muscles surrounding the areas affected by exostoses.
- Occupational therapy: Useful for patients who experience fine motor difficulties due to exostoses in the hands or wrists.
- Orthopedic bracing: Sometimes used to manage limb-length discrepancies or deformities caused by the condition.
- Pain management: Including heat/cold therapy and non-steroidal anti-inflammatory drugs (NSAIDs) for managing localized discomfort.
Are there medications or emerging treatments for Hereditary multiple exostoses?
Currently, there are no FDA-approved disease-modifying medications to stop the formation of growths in Hereditary multiple exostoses. Pharmacological management is strictly symptomatic. Researchers are investigating the role of the EXT1 and EXT2 genes in the pathogenesis of the disease, and some clinical trials are exploring potential pathways to inhibit tumor growth, though these are largely in early stages and not yet standard clinical practice. Always consult with your medical team before starting any new medication or supplement.
Which specialists should be on my care team?
Managing Hereditary multiple exostoses requires a multidisciplinary approach to address the systemic nature of the condition. Your care team should ideally include:
- Orthopedic Surgeon: Specifically one with experience in pediatric or tumor-related orthopedics.
- Genetic Counselor: To help understand the autosomal dominant inheritance pattern and family planning.
- Physical Therapist: To preserve range of motion and functional independence.
- Pain Management Specialist: If chronic pain significantly impacts your quality of life.
- Oncologist: For long-term surveillance, as there is a small (estimated 1–5%) lifetime risk of malignant transformation of an osteochondroma into chondrosarcoma.
Next steps
- Schedule a consultation with an orthopedic specialist who has specific experience with Hereditary multiple exostoses.
- Maintain a "growth log" to track the size and location of new or existing exostoses to share with your physician during check-ups.
- Connect with the 266 members on DiseaseMaps.org to share experiences and coping strategies.
- Request a referral to a genetic counselor to discuss the hereditary implications for your family members.

Surgery may be required to relieve pain, improve movement, restore normal circulation, or for cosmetic reasons.
Monitoring the size of affected bones by annual scans to screen for malignant degeneration is sometimes recommended. In that condition surgery is needed.
Rapid growth and increased pain are signs of a possible malignant change.
Genetic counseling is recommended for affected individuals and their families.
