OBSOLETE: Fibular hemimelia, unilateral

Fibular hemimelia, also known as fibular deficiency or absence of the fibula, is a condition present at birth where the fibula bone (the smaller bone on the outer side of the lower leg) is partially or completely missing on one side of the body. When it affects only one leg, it is called unilateral fibular hemimelia. This is the most common long bone deficiency seen in children. The condition can range from mild shortening of the fibula to its complete absence. Because the fibula plays a role in ankle stability and leg growth, children with this condition often have a shorter leg on the affected side, an unstable or abnormally shaped ankle, and sometimes missing toes or a bowed tibia (shinbone). The foot on the affected side may be smaller and may point inward or outward. In some cases, the knee joint may also be affected. Treatment depends on the severity and may include limb lengthening surgery, use of prosthetics, bracing, or in more severe cases, amputation followed by prosthetic fitting to allow better function and mobility. Many children with fibular hemimelia go on to lead active, fulfilling lives with appropriate treatment and support. Note: This specific Orphanet entry (295081) is marked as obsolete, meaning it may have been merged into a broader classification of fibular hemimelia.
