- What it is
- The ankle bone: a domed trochlea gripped by the malleoli above, a neck and a rounded head that fits the navicular.
- Function
- Transmits the entire body weight from the tibia to the foot; no muscles attach to it.
- Size
- ≈ 5.5 cm long
- Clinical note
- Most of its surface is cartilage, so its blood supply is fragile and neck fractures risk avascular necrosis.
