Achondroplasia is a form of short-limbed dwarfism.
- The word achondroplasia literally means “without cartilage formation.”
- Cartilage is a tough but flexible tissue that makes up much of the skeleton during early development.
- However, in achondroplasia the problem is not in forming cartilage but in converting it to bone (a process called ossification), particularly in the long bones of the arms and legs.
- Achondroplasia is similar to another skeletal disorder called hypochondroplasia but the features of achondroplasia tend to be more severe.
