Ultrasound Assessment of the Anatomic Landmarks for Spinal Anesthesia in Patients With Hip Fracture

Ultrasound Assessment of the Anatomic Landmarks for Spinal Anesthesia in Patients With Hip Fracture

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.

Inclusion Criteria:

• Patients scheduled for hip fracture surgery under spinal anesthesia

Exclusion Criteria:

• Anatomic abnormalities or masses in the spine
• History of spinal surgery of compression fracture
