Brief summary

Investigators assess the anatomic landmarks for spinal anesthesia in patients with hip fracture using ultrasonography.

Detailed description

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.

Interventions

DIAGNOSTIC_TESTNoninvasive ultrasound assessment

An investigator evaluate the L4-5 interspinous level using anatomic landmarks in turn, then another independent investigator assess the consistency of the landmarks-guided interspinous level with the actual one by noninvasive ultrasound assessment.

Masking description

An investigator evaluate the interspinous level using anatomic landmarks, then other independent investigator assess the consistency of the landmarks-guided interspinous level with the actual one using ultrasonography. Participants are blinded to the assessment results.
