Diagnostic yield of 8G versus 11G transpedicular vertebral biopsy needles in suspected tuberculous spondylitis: a prospective randomized controlled study

Listen to this summary

The authors aimed to compare the diagnostic yield and complication rates of 8G versus 11G transpedicular vertebral biopsy needles in patients suspected of tuberculous spondylitis. The study found no significant differences in diagnostic outcomes or complications between the two needle sizes, with both groups yielding similar rates of diagnostic samples and complications. Overall, the results suggest that either needle size can be effectively used for biopsies in this context.
