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.

Is fibular Hemimelia a disability?

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.

What is fibular deficiency?

Fibular Deficiency is a congenital condition caused by shortening or absence of the fibula which typically presents with anteromedial bowing of the tibia and a leg length discrepancy.

What is the cause of fibular Hemimelia?

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.

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.

Can you walk without a fibula?

The fibula is a long, thin bone of the outer leg alongside the shinbone. It is sometimes used to harvest bone that can be used in certain reconstructive surgeries of bone. The fibula can be removed without impacting the individual’s ability to walk or bear weight.

What causes fibula Hemimelia?

What is a fibular flap?

A fibular free flap is one way of filling a bony hole in either the upper or lower jaw. It is one of the common ways of replacing bone that has been removed for cancer treatment.

What is the diagnosis of fibular hemimelia 1?

Fibular hemimelia is a congenital lower limb anomaly characterized by partial or complete absence of the fibula and includes a spectrum ranging from mild fibular hypoplasia to complete fibular aplasia 1.

Where are the growth plates located in fibular hemimelia?

The fibular growth plates are displaced from their natural levels, establishing a position distal to the tibial growth plate proximally and proximal to the talar dome distally. The tibial spine may be absent, indicating a lack of the ACL.

When to consider a corrective osteotomy for fibular hemimelia?

If the residual stump is too short or bowed for prosthetic fitting, lengthening or corrective osteotomy may be considered. Distal tibial and fibular epiphysiodesis should be considered to create a discrepancy in the tibial segment length as the child grows.

How is the diagnosis of fibular deficiency made?

Diagnosis is made with radiographs of the tibia. Treatment may be observation or operative depending on degree of fibular deficiency, presence and severity of bowing, and severity of leg length discrepancy.
