Skeletal dysplasias

An osteochondrodysplasia, or skeletal dysplasia, is a disorder of the development of bone and cartilage. Osteochondrodysplasias are rare diseases. About 1 in 5,000 babies are born with some type of skeletal dysplasia. Nonetheless, if taken collectively, genetic skeletal dysplasias or osteochondrodysplasias comprise a recognizable group of genetically determined disorders with generalized skeletal affection. These disorders lead to disproportionate short stature and bone abnormalities, particularly in the arms, legs, and spine. Skeletal dysplasia can result in marked functional limitation and even mortality.

Osteochondrodysplasias or skeletal dysplasia subtypes can overlap in clinical aspects, therefore plain radiography is absolutely necessary to establish an accurate diagnosis. Magnetic resonance imaging can provide further diagnostic insights and guide treatment strategies especially in cases of spinal involvement. As some disorders that cause skeletal dysplasia have treatments available, early diagnosis is particularly important, but may be challenging due to overlapping features and symptoms that may also be common in unaffected children.
