Your fibula is located in your lower leg, specifically on the outer side, running parallel to your tibia (shinbone). It's the smaller of the two bones in your lower leg.
Fibula: Anatomy and Location
The fibula, also known as the calf bone, plays a crucial role in lower leg structure and ankle stability.
- Position: It's situated laterally (on the outside) to the tibia.
- Size: Significantly smaller than the tibia.
- Knee Joint: The top end of the fibula is below the knee joint but isn't a part of the joint itself.
- Ankle Joint: The lower end forms the outer part of the ankle joint.
- Function: Provides structural support to the lower leg and contributes to ankle stability. It also serves as an attachment point for several muscles.

Clinical Significance
Fractures of the fibula are relatively common, often occurring alongside tibia fractures or as a result of ankle sprains.
