Unclassified tibial hemimelia.

Tibial hemimelia (congenital longitudinal deficiency of the tibia) is rare (1 in 1 000 000). There are several classifications in the literature. We report an unclassified case of tibial hemimelia. A 6-year-old girl presented with shortening of the right lower limb, with a small rudimentary foot (presence of all toes) and hyper lax ankle. Quadriceps function was excellent. Radiograph showed a partial tibia and fibula in synostosis. The Jones and Kalamachi type 2 classifications both mention similar tibial anomalies; however, the fibula is normal in both varieties. The present variety can be considered as a variant of type 2 tibial hemimelia.
