NCT04964804

Brief Summary

The study is aimed at patients with low back and leg pain. The experimental group of patients underwent selective lumbar nerve root block puncture under real-time ultrasound-CT fusion imaging by sonographers, and the control group underwent puncture under the guidance of ultrasound alone by sonographers.
