Achondroplasia: This form of dwarfism is characterized by short stature, abnormal body proportion (limbs are shorter than normal while the torso remains of average size), and facial deformities.
The four most common causes of dwarfism in children are achondroplasia, Turner syndrome, inadequate pituitary function (pituitary dwarfism), and lack of emotional or physical nurturance.
Achondroplasia (short-limbed dwarfism) is a genetic disorder that impairs embryonic development, resulting in abnormalities in bone growth and cartilage development.
In achondroplasia, the long bones fail to develop normally, making the arms and legs disproportionately short and stubby (and sometimes curved).
In some cases physical development may be disproportionate, as in achondroplasia, but in others the parts of the body develop proportionately.
Chiari malformations are found in several known genetic disorders such as achondroplasia, Hadju-Cheney syndrome, and Klippel-Feil syndrome.
Achondroplasia occurs in all races and with equal frequency in males and females and affects about one in every 40,000 children.
There is no specific treatment for achondroplasia, besides treating any orthopedic problems that may arise.
Of these, Achondroplasia is the most common, affecting about 80 percent of all little people.
