Short answer · Medically reviewed summary · Last updated: 2026-04-07
Multiple epiphyseal dysplasia is classified under the ICD-10 code Q77.3, which covers chondrodysplasia with defects of growth and tubular bones. In the older ICD-9 coding system, this condition was historically classified under code 756.4, which refers to chondrodystrophy. What exactly is Multiple epiphyseal dysplasia? Multiple epiphyseal dysplasia (MED) is a group of rare genetic skeletal disorders that primarily affect the development of the ends of long bones (epiphyses).

Multiple epiphyseal dysplasia is classified under the ICD-10 code Q77.3, which covers chondrodysplasia with defects of growth and tubular bones. In the older ICD-9 coding system, this condition was historically classified under code 756.4, which refers to chondrodystrophy.
What exactly is Multiple epiphyseal dysplasia?
Multiple epiphyseal dysplasia (MED) is a group of rare genetic skeletal disorders that primarily affect the development of the ends of long bones (epiphyses). Because these bones are essential for joint formation, individuals with Multiple epiphyseal dysplasia often experience joint pain, stiffness, and an increased risk of early-onset osteoarthritis. The severity of the condition varies significantly between patients; some may only experience mild hip or knee discomfort, while others may have more widespread skeletal involvement. Currently, 89 people living with Multiple epiphyseal dysplasia have joined the DiseaseMaps community, sharing their unique journeys and helping others navigate the challenges of this diagnosis.
Is Multiple epiphyseal dysplasia hereditary?
Yes, Multiple epiphyseal dysplasia is a genetic condition. It can be inherited in either an autosomal dominant or an autosomal recessive pattern, depending on the specific gene mutation involved. Mutations in several genes, including COMP, COL9A1, COL9A2, COL9A3, MATN3, and DTDST, have been identified as causes of Multiple epiphyseal dysplasia. Because of the complex genetic landscape, clinical geneticists often recommend specialized testing to confirm the specific mutation, which can provide clearer expectations regarding the progression of the disease within a family.
How is the condition diagnosed and managed?
Diagnosis of Multiple epiphyseal dysplasia is typically confirmed through a combination of clinical evaluation, family history, and radiographic imaging. X-rays often reveal delayed or irregular ossification of the epiphyses. While there is no cure, management focuses on preserving joint function and managing chronic pain. Common clinical management strategies include:
- Regular monitoring by a pediatric orthopedist or a rheumatologist.
- Physical therapy to maintain range of motion and strengthen muscles surrounding the affected joints.
- Pain management protocols tailored to the individual’s level of joint discomfort.
- Surgical interventions, such as osteotomies or joint replacements, which may be required in later stages if severe joint degeneration occurs.
What are the psychosocial impacts of living with the disease?
Living with a chronic skeletal condition like Multiple epiphyseal dysplasia can be emotionally taxing, particularly during childhood and adolescence when physical activity levels differ from peers. Our team of clinical psychologists emphasizes that managing the "invisible" burden—such as chronic pain or the fatigue associated with mobility issues—is just as important as medical treatment. Connecting with others who understand the nuances of Multiple epiphyseal dysplasia can significantly reduce feelings of isolation and improve overall quality of life.
Next steps
- Consult a clinical geneticist to discuss genetic testing and family planning options.
- Schedule an evaluation with an orthopedic specialist who has experience with skeletal dysplasias.
- Join the Multiple epiphyseal dysplasia community on DiseaseMaps.org to share experiences and find peer support.
- Maintain a consistent physical therapy routine to preserve joint mobility and function.
