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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Group 1 | Experimental | 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 | Experimental | 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. |

| Noninvasive ultrasound assessment | Diagnostic Test | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Accuracy of each anatomic landmark (Tuffier's line and tenth rib line). | Actual interspinous levels of the landmark-guided approches (Tuffier's line and tenth rib line) are assessed using ultrasonography. | Baseline |
| Measure | Description | Time Frame |
|---|---|---|
| The estimation ratio related to the intervertebral levels | Actual interspinous levels of the landmark-guided approches (Tuffier's line and tenth rib line) are assessed using ultrasonography. | Baseline |
