Hemimelic epiphyseal dysplasia: a case report

Area of Science:

• Orthopedics
• Pediatric Radiology
• Developmental Biology

Background:

• Hemimelic epiphyseal dysplasia (HED), also known as Trevor's disease, is a rare developmental disorder affecting limb epiphyses in children and adolescents.
• The etiology of HED is unknown, and its clinical presentation varies widely, from asymptomatic cases to significant orthopedic complications like limb length discrepancy.

Observation:

• Clinical presentation of HED is often non-specific, necessitating advanced radiological assessment (X-ray, MRI, CT) for diagnosis.
• Differential diagnoses, including osteochondroma and exostosis, can complicate HED diagnosis due to its rarity.

Findings:

• Radiological findings are crucial for diagnosing HED, distinguishing it from more common bone conditions.
• Despite diagnostic challenges, HED generally has a favorable prognosis with no risk of malignant transformation.

Implications:

• Accurate and timely diagnosis of HED is essential for appropriate orthopedic management and preventing complications.
• Treatment strategies for HED range from observation to surgical intervention, with potential complications including recurrence and secondary osteoarthritis.
