What is Fibular Hemimelia? Fibular hemimelia is a birth defect where part or all the fibular bone is absent. Most often is unilateral. Diagnosis and Causes Can be observed at scans during pregnancy. Shortened leg, ankle or knee instability due to absence of fibula bone. Most cases of fibular hemimelia are thought to occur for no reason.

Fibular Hemimelia Types Type 1: Short or partial proximal absence unilaterally 1A: Stable ankle joint ± ball & socket joint with mostly medial tilt. 1B: Unstable ankle joint with proximal fibula is absent 30-50% of its length.

Fibular Hemimelia Types Type 2: Complete absence Can be unilateral or bilateral. Tibia be extremely small and bowed with proximal femoral focal and upper limb deficiency.

Treatment Treatment will depend on the severity and condition of the limb. Choices consist of either amputation of lower leg or tibia lengthening or tibia lengthening.
