Aim:
To investigate the difference in radiation exposure to the patients between oblique and posteroanterior view, initial approach techniques in fluoroscopy-guided lumbosacral transforaminal epidural steroid injections.
Patients & Methods:
Total amount of Kerma area product, elapsed time of the procedure and fluoroscopy time were obtained from medical records retrospectively.
Results:
28 patients were included in each group. Fluoroscopy time was significantly lower in group 1, but there was no statistically significant difference in terms of procedure time and Kerma area product.
Conclusion:
Radiation risk does not change between these approaches.
