The left tibia is foreshortened, thickened and bowed anteromedially. The left fibula is absent. There is evidence of talipes equinovalgus deformity.
The lateral rays and phalanges (4th and 5th digits) are also absent.
Findings are consistent with type II Fibular hemimelia.
Although rare in occurrence, it is the most common congenital absence of long bone of the extremities.
Fibular hemimelia classification is that of Achterman and Kalamachi et al, which divides the condition into two types:
- type I: minimal hypoplasia of the fibula
- type II: complete absence of the fibula
