Details and patient eligibility

About

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

Full 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.

Enrollment: 84 patients

Sex: All

Ages: 65+ years old

Volunteers: No Healthy Volunteers

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

Trial design

Primary purpose: Diagnostic

Allocation: Randomized

Interventional model: Crossover Assignment

Masking: Double Blind

84 participants in 2 patient groups

Group 1

Experimental group

Description:

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.

Treatment:

Diagnostic Test: Noninvasive ultrasound assessment

Group 2

Experimental group

Description:

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.
