Congenital fibular deficiency

Area of Science:

• Orthopedics
• Pediatric Orthopedics
• Genetics

Background:

• Congenital fibular deficiency (CFD) encompasses a broad range of limb malformations, from mild limb length inequality (LLI) to severe shortening, often with foot and ankle deformities.
• The precise etiology of CFD is not yet fully understood.
• Treatment aims to restore weight-bearing capacity, achieve a plantigrade foot, and equalize limb length.

Purpose of the Study:

• To review the current understanding and treatment strategies for congenital fibular deficiency (CFD).
• To evaluate the effectiveness of different treatment modalities based on the proposed Birch classification system.
• To discuss the evolving role of limb lengthening versus reconstructive or ablative procedures in managing CFD.

Main Methods:

• Literature review of congenital fibular deficiency (CFD) treatment options.
• Analysis of outcomes comparing amputation and limb lengthening procedures.
• Consideration of the Birch classification system for guiding treatment decisions.

Main Results:

• Amputation for severe CFD demonstrates favorable outcomes with fewer complications compared to limb lengthening.
• The Birch classification system aids in tailoring treatment based on foot function, LLI, and associated anomalies.
• Current data suggests amputation is often preferred for severe presentations.

Conclusions:

• Treatment decisions for congenital fibular deficiency (CFD) require careful consideration of the individual's presentation and the proposed Birch classification.
• While amputation yields good results for severe CFD, advances in limb lengthening may broaden reconstructive options in the future.
• Further research into CFD etiology and long-term outcomes of various treatments is warranted.
