Tibial Distance (TD) to the tibial nerve
Day 1
Subjects will be placed in a right lateral decubitus position on a bed. Seven marks will be made with a dermal marker from the lower edge of the right tibial malleolus, following the medial edge of the tibial bone in the cranial direction. Measurements will be taken at 2, 4, 5, 6, 8, 10, and 12 cm with respect to the lower edge of the tibial malleolus. The most superficial aspect of the tibia will be considered for the measurements.
The measurements will be performed using an ultrasound machine (ALPINIONⓒ, Seoul, South Korea, model ECUBE 8LEⓇ) with a linear probe L3-12T (frequency range 3-12 MHz), using the Rehabilitative Ultrasound Imaging (RUSI) method.
The distance will be measured using a caliper by drawing a straight line from the most medial aspect of the tibia to the most anterior aspect of the nerve, taking into consideration the outer edge of the tibial nerve wall. This will be analyzed at each of the 7 marks previously described
Tibial Distance (TD) to the tibial artery
Day 1
Subjects will be placed in a right lateral decubitus position on a bed. Seven marks will be made with a dermal marker from the lower edge of the right tibial malleolus, following the medial edge of the tibial bone in the cranial direction.

Tibial Distance (TD) to the tibial vein
Day 1
Subjects will be placed in a right lateral decubitus position on a bed. Seven marks will be made with a dermal marker from the lower edge of the right tibial malleolus, following the medial edge of the tibial bone in the cranial direction. Measurements will be taken at 2, 4, 5, 6, 8, 10, and 12 cm with respect to the lower edge of the tibial malleolus. The most superficial aspect of the tibia will be considered for the measurements.
