fibula
C2Technical, Formal, Academic
Definition
Meaning
The outer and smaller of the two bones in the lower leg, between the knee and the ankle.
A clasp or brooch used in ancient Greece and Rome, often resembling a modern safety pin; or, by analogy in biology, a bone or structure in certain animals that corresponds to the human fibula.
Linguistics
Semantic Notes
In anatomy, it is the non-weight-bearing bone of the lower leg. The primary term in anatomy; in everyday speech, people often refer generally to the 'lower leg bones' or use 'shin bone' (tibia) without specifying the fibula. The ancient jewellery sense is primarily used in archaeology and art history.
Dialectal Variation
British vs American Usage
Differences
No significant difference in anatomical meaning. Minor potential differences in the archaeological/jewellery context regarding museum cataloguing conventions.
Connotations
Neutral and technical in both varieties. The jewellery sense carries connotations of classical antiquity.
Frequency
Very low frequency in everyday conversation in both varieties. Equally common in medical and biological contexts.

Learning
Memory Aids
Mnemonic
Think: 'FIBula is a FIBre-like bone' (long and thin) or 'My FIBula tells a little FIB - it's not the main weight-bearing bone (that's the tibia).'
Conceptual Metaphor
A SUPPORTING STRUCTURE (as it provides muscle attachment and stabilises the ankle, but is not the main pillar).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Mistaking it for 'малая берцовая кость' (which is correct). Potential confusion with 'fibre' (волокно) due to similarity in spelling.
Common Mistakes
- Mispronouncing it as /faɪˈbjuː.lə/.
- Confusing it with the tibia (shin bone).
- Using it as a general term for 'leg bone'.

FAQ
Frequently Asked Questions
It can be, particularly if it involves the ankle joint (a 'malleolar fracture'), but an isolated fibula shaft fracture is often less severe than a tibia fracture and may heal with just a brace or cast.
The tibia (shin bone) is the larger, weight-bearing bone on the inner side of the lower leg. The fibula is the thinner, non-weight-bearing bone on the outer side, primarily for muscle attachment and ankle stability.
Often, yes, especially if it's a stable, isolated fracture. Doctors may allow 'weight-bearing as tolerated' with a protective boot. However, this depends entirely on the specific fracture type and location.
It comes from Latin 'fibula', meaning 'clasp, brooch, pin'. The bone was named for its resemblance to the pin of a Roman brooch. The jewellery meaning is the original one.
