Conditions

Low Back Pain

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.

Detailed description

A total of 60 patients with low back and leg pain were randomly divided into two groups, 30 people in each group. Patients in the experimental group underwent selective lumbar nerve root block puncture under the real-time ultrasound-CT fusion imaging of the sonographer, and the control group underwent puncture under the sole ultrasound guidance of the sonographer. This study was used to compare the difference between the effects of pure ultrasound guidance and ultrasound-CT fusion imaging guidance on selective lumbar nerve root block.
