Hereditary Multiple Exostoses: Symptoms and Care
Hereditary Multiple Exostoses is a rare genetic disorder that causes the development of multiple benign bone tumors, known as osteochondromas, on the bones throughout the body. These growths can lead to various health complications, including skeletal deformities, restricted joint movement, and potential nerve compression. The presence of these bony outgrowths can impact an individual's physical functioning and overall quality of life.
What are the Symptoms of Hereditary Multiple Exostoses?
Hereditary Multiple Exostoses may present with various bone-related symptoms that can impact mobility and cause discomfort.
- Bony lumps or growths
- Joint pain
- Limited range of motion
- Numbness or tingling
- Bowing of the arms or legs
- Short stature
- Deformities in bones

Get Second OpinionCauses of Hereditary Multiple Exostoses
Hereditary Multiple Exostoses is primarily caused by genetic mutations that lead to the development of multiple benign bone tumors called exostoses.
- Genetic mutation
- Inherited from parents
- Autosomal dominant inheritance pattern
Types of Hereditary Multiple Exostoses
Hereditary Multiple Exostoses can manifest in various forms, affecting different parts of the body and causing a range of symptoms.
- Osteochondroma: The most common type of Hereditary Multiple Exostoses characterized by benign bony growths near the growth plates of long bones.
- Exostoses enchondralis: A type of Hereditary Multiple Exostoses where exostoses are predominantly composed of cartilage, affecting bone development and growth.
- Metaphyseal dysplasia: Hereditary Multiple Exostoses involving abnormal development of the metaphysis, leading to bony growths near the ends of long bones.
- Diaphyseal aclasis: A rare form of Hereditary Multiple Exostoses characterized by exostoses along the shafts of long bones, impacting bone structure and strength.
- Subungual exostosis: A type of Hereditary Multiple Exostoses affecting the bones beneath the nails, causing painful growths and deformities in the fingertips or toes.
Risk Factors
Hereditary Multiple Exostoses, a rare genetic disorder, is caused by mutations in certain genes and is more commonly seen in individuals with a family history of the condition. Risk factors for Hereditary Multiple Exostoses:
- Family history of Hereditary Multiple Exostoses
- Genetic mutations affecting EXT1 or EXT2 genes
- Inheritance pattern of autosomal dominant gene
- Male gender
- Advanced age

Diagnosis of Hereditary Multiple Exostoses
Hereditary Multiple Exostoses is typically diagnosed through a combination of clinical evaluation and imaging tests to assess the bone growths.
- Imaging tests such as Xrays, CT scans, and MRIs
- Genetic testing to identify specific gene mutations
- Physical examination to assess bone growth and identify exostoses
- Family history evaluation to look for patterns of inheritance
Treatment for Hereditary Multiple Exostoses
Treatment for Hereditary Multiple Exostoses focuses on managing symptoms and preventing complications associated with the condition.
Surgical Removal:
- Surgical removal may be necessary to alleviate pain, prevent deformity, or address complications caused by the bone tumors in Hereditary Multiple Exostoses.
Physical Therapy:
- Physical therapy can help improve joint mobility, strength, and function in individuals with Hereditary Multiple Exostoses, contributing to better overall quality of life.
Pain Management:
- Pain management techniques such as medication, corticosteroid injections, or nerve blocks can help alleviate discomfort associated with Hereditary Multiple Exostoses.
Orthotic Devices:
- Orthotic devices like braces or splints may be prescribed to provide support, reduce pain, and improve mobility in affected joints for individuals with Hereditary Multiple Exostoses.
Regular Monitoring:
- Regular monitoring by healthcare providers is crucial to track disease progression, manage symptoms, and address any potential complications associated with Hereditary Multiple Exostoses.

What is Hereditary Multiple Exostoses (HME)?
Hereditary Multiple Exostoses (HME) is a rare genetic disorder characterized by the growth of multiple benign bone tumors called osteochondromas.
What are the symptoms of Hereditary Multiple Exostoses?
Common symptoms include bony lumps near joints, limited range of motion, pain, and potential complications like nerve compression or skeletal deformities.
How is Hereditary Multiple Exostoses diagnosed?
Diagnosis typically involves a physical exam, imaging tests like x-rays or MRI, and genetic testing to confirm the presence of mutations in EXT1 or EXT2 genes.
What are the treatment options for Hereditary Multiple Exostoses?
Treatment may involve monitoring for changes, physical therapy, pain management, surgical removal of problematic osteochondromas, or orthopedic interventions to address complications.
Is Hereditary Multiple Exostoses curable?
There is no cure for HME, but early detection, regular monitoring, and appropriate management can help manage symptoms and reduce the risk of complications.
