Interosseous crest of fibula
Crista interossea fibulae
- Latin synonym: Margo interosseus fibulae
- Synonym: Interosseous border of fibula; Interosseous margin of fibula
Definition
The interosseus crest of fibula (nterosseus border of the fibula) is located just medial to (or inside) the prominent anterior border. It ends below at a rough triangular area positioned above the articular facet (or talar facet) of the lateral malleolus.
Several ligaments, such as the interosseus tibiofibular, anterior and posterior tibiofibular, and inferior transverse tibiofibular ligaments, connect this triangular area with the lower part of the tibia forming inferior tibiofibular joint. In its upper portion, the medial (or interosseus) border closely aligns with the anterior border, to the extent that they may appear indistinguishable from each other.
