What is Hypocondroplasia?
•Hypochondroplasia is a form of Dwarfism.
•Hypochondroplasia is a derivative of another skeletal disorder called achondroplasia, and the features tend to be milder.
•This condition affects the conversion of cartilage into bone (a process called ossification), particularly in the long bones of the arms and legs.
•Hypoachondroplasia usually consists of: Spinal Stenosis (narrowing of the spinal column from the base of the brain down to the lower spine), which can cause complications later on. Joint replacements (such as hips, knees, etc) may have to be considered in much later adulthood.
•People with hypochondroplasia may have short arms and legs with broad, short hands and feet. Other characteristic features include: a large head, limited range of motion at the elbows, a sway of the lower back (lordosis), and bowed legs. These signs are generally less pronounced than those seen with achondroplasia and may not be noticeable until early or middle childhood.
•People with hypochondroplasia have short stature.
•The adult height for men with this condition ranges from 138 centimetres to 165 centimetres (4 feet, 6 inches to 5 feet, 5 inches). The height range for adult women is 128 centimetres to 151 centimetres (4 feet, 2 inches to 4 feet, 11 inches).
