Conditions

Low Back Pain

Brief summary

The study is aimed at patients with low back and leg pain. The patients in the experimental group were guided by ultrasound-CT fusion imaging to insert the lumbar nerve root puncture needle. Patients in the control group underwent the insertion of the lumbar nerve root puncture needle under the guidance of ultrasound alone.

Detailed description

A total of 80 patients with low back and leg pain were randomly divided into two groups, 30 people in each group. The patients in the experimental group were guided by ultrasound-CT fusion imaging to insert the lumbar nerve root puncture needle.Patients in the control group underwent the insertion of the lumbar nerve root puncture needle under the guidance of ultrasound alone.Follow-up of VAS pain score after lumbar nerve root block treatment. This study aims to establish a standardized operation method and process for lumbosacral nerve ultrasound-CT fusion guided interventional pain treatment.
