[edit] Types of dwarfism rhizomelic = root, e.g. bones of upper arm or thigh mesomeli = middle, e.g. bones of forearm or lower leg acromelic = end, e.g. bones of hands and feet. When the cause of dwarfism is understood, it may be classified according to one of hundreds of names, which are usually permutations of the following roots: chondro = of cartilage osteo = of bone spondylo = of the vertebrae plasia = form trophy = growth Examples include achondroplasia, osseous dysplasia, chondrodystrophy, and osteochondrodystrophy.[2] The most recognizable and most common form of dwarfism is achondroplasia, which produces rhizomelic short limbs, increased spinal curvature, and distortion of skull growth. It accounts for 70% of dwarfism cases. Other relatively common types include spondyloepiphyseal dysplasia congenita (SED), diastrophic dysplasia, pseudoachondroplasia, hypochondroplasia, and osteogenesis imperfecta (OI). Severe shortness with skeletal distortion also occurs in several of the mu
