What is the history of Multiple epiphyseal dysplasia?

Multiple epiphyseal dysplasia (MED) was first formally described in the medical literature by Dr. H.J. Barrington Fairbank in 1935, who distinguished it from other skeletal dysplasias by identifying the characteristic delayed and irregular ossification of the epiphyses. Since its discovery, our understanding of Multiple epiphyseal dysplasia has shifted from a clinical diagnosis based solely on radiographic appearance to a precise molecular diagnosis driven by the identification of specific gene mutations.

When was Multiple epiphyseal dysplasia first described?

While various forms of skeletal irregularities were documented in the late 19th century, the clinical entity now known as Multiple epiphyseal dysplasia was clearly defined by the British orthopedic surgeon Sir H.J. Barrington Fairbank in 1935. Fairbank recognized that patients presented with a specific pattern of joint pain and gait abnormalities that did not fit the criteria for other known dwarfism syndromes. For decades, the diagnosis of Multiple epiphyseal dysplasia remained purely radiological, relying on X-ray evidence of flattened or fragmented epiphyses (the ends of long bones) to differentiate it from other osteochondrodysplasias.

How has our understanding of Multiple epiphyseal dysplasia evolved?

The history of this condition is a transition from observation to genetic mapping. In the mid-20th century, clinicians struggled with the heterogeneity of the disease, often confusing it with milder forms of pseudoachondroplasia. The modern era began in the 1990s when researchers identified the first genetic culprits. We now know that Multiple epiphyseal dysplasia is not a single disease but a group of genetically distinct disorders involving the cartilage matrix proteins.

What milestones changed the diagnosis of Multiple epiphyseal dysplasia?

The most significant leap in understanding occurred with the discovery of the specific genes responsible for the condition. The following milestones highlight how technology refined our knowledge:

• 1990s: The identification of mutations in the COMP (cartilage oligomeric matrix protein) gene, which accounts for a significant portion of autosomal dominant cases.


• Molecular Categorization: Discovery that mutations in genes such as COL9A1, COL9A2, COL9A3, and MATN3 also cause Multiple epiphyseal dysplasia.


• Clinical Differentiation: The ability to distinguish between the "Fairbank type" (more severe) and the "Ribbing type" (milder) through genetic testing rather than just clinical observation.


• Community Growth: Platforms like DiseaseMaps.org have allowed the 89 members currently in our community to share phenotypic data, which helps researchers better understand the natural history of the condition.

How have misconceptions about the condition been corrected?

Historically, patients with Multiple epiphyseal dysplasia were often misdiagnosed with early-onset osteoarthritis or "growing pains" in childhood. Because the condition often presents with subtle physical signs—such as a waddling gait or mild short stature—it was frequently overlooked or dismissed. The development of high-resolution genetic sequencing has effectively corrected these misconceptions, allowing for early diagnosis and preventing unnecessary or incorrect interventions.

Next steps

• Consult a clinical geneticist to discuss whether genetic testing is appropriate for you or your family members.


• Schedule a consultation with a pediatric orthopedic specialist to monitor joint health and manage potential early-onset arthritis.


• Join the Multiple epiphyseal dysplasia community on DiseaseMaps.org to connect with others who have shared their experiences and treatment journeys.


• Keep a detailed log of your joint symptoms and physical history to assist your medical team in creating a personalized management plan.
