Q72.6: Longitudinal reduction defect of fibula

There are 2 bones in the lower leg, the tibia and the fibula. The tibia is on the inside of the leg. The fibula is on the outside of the leg. Both bones in the lower leg have an upper, middle and lower section.

There may be a number of different reasons for the fibula not properly developing. Certain congenital diseases can lead to an improperly developed fibula, for example. Taking certain medication during pregnancy can result in the child’s fibula not being properly developed. This means the child’s leg can be bent or shortened, for example.
