Abstract

STUDY DESIGN: Retrospective study. PURPOSE
Facet joint block is performed for diagnostic or therapeutic purpose
s and generally carried out under computerd tomography (CT) or radiologic fluoroscopy guidance. Ultrasonography-guided facet block has recently been attempted. So, we compared the results of ultrasonography-guided facet joint block with the results of fluoroscopy-guided facet joint block. OVERVIEW OF LITERATURE: Because fluoroscopic or CT guided facet joint block has been reported side effects, we performed spinal facet block using a fluoroscopy-guided method.
METHODS
We selected 133 patients who had lumbar pain or referred pain. They were diagnosed as having spinal stenosis and hospitalized from January 2008 to June 2008. As the subjects, we selected 105 patients who had been follow-up for more than 6 months and carried out a prospective study.
RESULTS
The procedure in group 2 averaged 4 minutes and 25 seconds, and in group 1, 4 minutes and 7 seconds. The coast was an average of 38,000 won in group 2 and 25,000 won in group 1. The VAS score was improved from an average of 7.5 (range, 5 to 9) to 2.8 (range, 2 to 6) in group 2 and from 7.8 (range, 4 to 10) to 2.7 (range, 2 to 5) in group 1. The Oswestry disability index was improved from an average of 32.3 (range, 28 to 41) to 23.5 (range, 17 to 26) in group 2 and from 34.2 (range, 29 to 43) to 24.8 (range, 18 to 28) in group 1. As for complications, worsening of lumbar pain, paresthesia, headache and allergic reaction were detected in 5 cases of group 2 and in 3 of group 1. Those symptoms were improved within several hours. One case of superficial infection that developed in group 2 was improved within several days. CONCLUSIONS: We should consider that ultrasonography-guided facet joint block is a minimal invasive procedure that is easily carried out without radiation exposure.
