What is fibula hemimelia?
What Is Fibular Hemimelia? Children who have fibular hemimelia are born with a short or missing fibula (one of the two bones in the lower leg). Other bones in the leg, ankle, and foot can be affected too. Most children with fibular hemimelia (FIB-yoo-luhr heh-me-MEEL-yuh) have it in one leg, but some have it in both.

What is the cause of fibular hemimelia?
What causes fibular hemimelia? In many cases, the cause of fibular hemimelia is unknown. Studies have shown that the condition can be related to genetic abnormalities. However, these seem to occur randomly and are not passed down from parents to children.
Is fibular hemimelia a disease?
Fibular hemimelia is a birth defect where part or all of the fibular bone is missing, as well as associated limb length discrepancy, foot deformities, and knee deformities. Fibular hemimelia (FH) is a very rare disorder, occurring in only 1 in 40,000 births.
When is fibular hemimelia diagnosed?
Fibular hemimelia (FH) is a congenital longitudinal limb deficiency characterized by complete or partial absence of the fibula. Typically, it has been diagnosed at birth, when the neonate is seen to have lower limb shortening and a foot with missing toes.
