What leg rotation is recommended for optimal distal tibial and pedal arterial access?

Explanation:
External rotation lines the leg so the distal tibial and pedal arteries sit more directly in line with the skin and access path, making cannulation easier and more reliable. By turning the leg outward, the vessels become more superficial and aligned, reducing vessel tortuosity and improving palpation or ultrasound guidance. In contrast, twisting the leg the other way can kink or obscure the arteries, and neutral positioning or simply focusing on ankle movement (dorsiflexion) doesn’t optimize the vessel axis for distal tibial and pedal access. Maintain gentle external rotation with proper support to protect surrounding structures.
