Hereditary multiple exostoses is a rare congenital condition with autosomal dominant inheritance. It consists of formation of osteocartilaginous exostoses, most commonly from the metaphysis of long bones. Surgery is the main treatment as there is no available medical treatment. Clinical follow-ups with orthopaedic specialists are important, both in childhood and adulthood. In childhood, focus is on managing symptoms and removing symptomatic exostoses, while in adulthood, MRI is performed to rule out malignant transformation, as argued in this review.
