What is a fibular defect?

Fibular defect (also known as fibular hemimelia) is a congenital deformity of the leg and refers to the partial to complete absence of the fibula (calf bone). The cause remains unknown to this day. It is clear, however, that this is not a genetic defect.

The absence of the fibula causes leg asymmetry. Approximately 10% of cases involve both legs. The affected leg is significantly shortened and there is a valgus deformity in the lower leg.

The fibular defect occurs either alone or in combination with PFFD (proximal focal femoral deficiency), anomalies of the foot and/or hips.

In the case of a partial absence of the fibula, this is referred to as hypoplasia (type 1a/1b). The calf bone is still present here, but underdeveloped. The complete absence of the fibula is called aplasia (type 2).

Patient with orthoprostheses

Caring for children and adolescents with fibular defects is part of our daily work. Contrary to some assumptions, aplasia can also be treated very well with orthoprostheses. There is hardly any patient that we can't get back up and running.

Patient stories

Juna is a super athlete. She loves water and everything that moves quickly. Perhaps that’s why the six-year-old likes to ride roller blades and skates. At first glance, many people don't even notice that Juna wears two aids on her legs.
