"type I: partial hypoplasia of the fibula"
"type II: complete absence of the fibula"
"Several theories have been put forward to explain this condition, such as defects in the apical ectoderm ridge or defects secondary to an absent anterior tibial artery 3. Amniotic bands may be a factor causing insult to the growing limb bud in utero, resulting in this condition 4. There has been a case of congenital absence of femur and fibular hemimelia related to maternal hyperpyrexia 5."
