A disorder that results in abnormal bone growth and dwarfism is:
achondroplasia
The group of fetal head and brain abnormalities that often coexsist with spina bifida is referred to as
arnold chiari II malformation

massa intermedia
Rhizomelis denotes
shortening of the proximal segment of a limb
An absent sacrum and coccyx is referred to as:
caudal regression syndrome
