Abstract

PURPOSE
To evaluate the effectiveness of a selective nerve root block (SNRB) in patients with sciatica before surgery through a more than 5 year follow up.
MATERIALS AND METHODS
Between January 2000 and December 2000, patients with sciatica, who were recommended to undergo surgery to diagnose and treat sciatica by other clinics or at our hospital, were selected to undergo SNRB before surgery. Among them, 69 patients were followed up for 5 years. The analysis was based on the patients' medical records and telephone interviews, and the treatment results in the SNRB group and operation group were analyzed using Kim's criteria and the Visual Analog Scale score.
RESULTS
Among the 69 patients, there was no improvement in symptoms in 37 patients after SNRB. Therefore, they underwent surgery. The symptoms of the remaining 32 patients were improved by SNRB. Overall, younger patients and those with a longer symptom duration required surgery.
CONCLUSION
SNRB was performed on patients with sciatica who were scheduled to undergo surgery. Some patients showed improvement in their symptoms in the long term. Therefore, SNRB should be considered as a treatment option prior to surgery.
