Yes, the ankle can rotate, although it has a limited range of motion. According to reference information, rotation occurs around the heel.
Understanding Ankle Rotation
The ankle's ability to rotate allows for movements beyond simple up-and-down (dorsiflexion and plantarflexion). While the primary motions at the ankle joint complex are dorsiflexion and plantarflexion, some rotation is possible.
How Ankle Rotation Works
- Limited Range: The ankle's rotation range is not extensive compared to joints like the hip or shoulder.
- Heel as Pivot: Rotation primarily occurs with the heel on the ground.
- Movement Example: When sitting with the heel on the ground and the ball of the foot slightly lifted (dorsiflexion), you can pivot the foot inwards (internal rotation) or outwards (external rotation).
Types of Ankle Rotation
- Internal Rotation (Inversion): Pivoting the foot so the sole faces inward.
- External Rotation (Eversion): Pivoting the foot so the sole faces outward.
Practical Implications
The limited rotation at the ankle plays a role in:
- Adapting to uneven surfaces.
- Maintaining balance during movement.
- Contributing to the overall flexibility of the lower limb.
