The exact cause of fibular hemimelia is unknown. A spontaneous genetic error occurs during limb bud development. This growth abnormality occurs during the development of the lower limb bud at six to eight weeks after conception.
What causes 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.
Who suffered from fibular 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.
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.
How common is fibular Hemimelia?
Fibular hemimelia is a congenital longitudinal limb deficiency characterized by complete or partial absence of the fibula bone. Prevalence is estimated at 1 in 50,000.
What does Hemimelia mean?
Medical Definition of hemimelia : a congenital abnormality (as total or partial absence) affecting only the distal half of a limb.
How common is fibular hemimelia?
Is fibular Hemimelia life threatening?
Fibular deficiency is usually a benign condition, although in severe cases it can be debilitating. Acceptable functional results may be achieved by surgery. In case of syndromic presentation, prognosis depends on the nature of the associated anomalies.
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.
The exact cause of fibular hemimelia is unknown. A spontaneous genetic error occurs during limb bud development. This growth abnormality occurs during the development of the lower limb bud at six to eight weeks after conception.
What is the Birch classification for fibular hemimelia?
The Birch classification divides fibular hemimelia into two categories based on the potential of the foot to be reconstructed. In Type 1, the foot is reconstructable, whereas in Type 2, it is not.
What are the treatment options for hemimelia?
Fibular Hemimelia Treatment. Fibular hemimelia requires surgical intervention in all cases. There are two main possibilities when it comes to such matters: a procedure to lengthen the affected limb (Ilizarov’s technique) or the amputation of the respective limb, followed by the application of a fitted prosthesis.
What is the incidence of congenital absence of the fibula?
Also known as congenital absence of the fibula, congenital fibular deficiency, paraxial fibular hemimelia and aplasia/hypoplasia of the fibula, fibular hemimelia has an incidence of 7.4 per 20 million live births, making it the most common long bone deficiency.
