| Sumario: | Objectives: To explore the feasibility and efficacy of the segmental localization of lumbar vertebrae by ultrasound (US) compared with X-ray. Methods: From February 2019 to May 2019, 43 patients (24 males and 19 females), with an average age of 46±15 years, were prospectively enrolled in this study. Longitudinal paramedian sagittal and transverse process sections were used to determine the lumbar segments by US scan. X-ray examination was used to verify the segmentation. The time for segmentation was recorded, and the learning curve of the average localization time was analyzed. Results: Of all the enrolled patients, 5 had lumbar segmental and alignment abnormalities, and 38 had normal lumbar vertebrae. US accurately located vertebrae in 38 normal cases and 5 abnormal cases, with a 100% accuracy rate, as verified by X-ray examination. The localization time was significantly less for US than for X-ray examination, both in normal cases and in cases with segmental or alignment abnormalities (all P < 0.001). The learning curve of US-guided segmental localization continuously decreased with an increasing number of operations and entered the plateau stage after the third operation day. Conclusions: The US-guided segmental localization of lumbar vertebrae is an accurate new method that is efficient and easy to learn and does not require radiation. |
