Investigators assess the anatomic landmarks for spinal anesthesia in patients with hip fracture using ultrasonography.
Investigators evaluate the anatomic landmarks using Tuffier's line and the tenth rib line for spinal anesthesia in patients with hip fracture, and then assess the consistency of the landmarks-guided interspinous levels with the actual interspinous level using ultrasonography.
