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

Not Applicable

Completed

• Conditions: Hip Fractures
• Interventions: Diagnostic Test: Noninvasive ultrasound assessment

• Registration Number: NCT03182608
• Lead Sponsor: SMG-SNU Boramae Medical Center

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.

Arm && Interventions

Group	Intervention	Description
Group 1	Noninvasive ultrasound assessment	In the lateral decubitus position, an investigator evaluate the L4-5 interspinous level using an anatomic landmark (Tuffier's line), and then evaluate the L4-5 interspinous level using another anatomic landmark (Tenth rib line). Another investigator evaluate the actual L4-5 interspinous level by noninvasive ultrasonography.
Group 2	Noninvasive ultrasound assessment	In the lateral decubitus position, an investigator evaluate the L4-5 interspinous level using an anatomic landmark (Tenth rib line), and then evaluate the L4-5 interspinous level using another anatomic landmark (Tuffier's line). Another investigator evaluate the actual L4-5 interspinous level by noninvasive ultrasonography.

Primary Outcome Measures

Name	Time	Method
Accuracy of each anatomic landmark (Tuffier's line and tenth rib line).	Baseline	Actual interspinous levels of the landmark-guided approches (Tuffier's line and tenth rib line) are assessed using ultrasonography.

Secondary Outcome Measures

Name	Time	Method
The estimation ratio related to the intervertebral levels	Baseline	Actual interspinous levels of the landmark-guided approches (Tuffier's line and tenth rib line) are assessed using ultrasonography.
