THE USE OF ADHESIVE RADIOPAQUE GRIDS IN GENICULAR NERVE BLOCK BY RADIOSCOPY
ABSTRACT The performance of genicular nerve block requires an imaging method to guide the procedure. Radioscopy has the disadvantage of being radiation dependent. Objective: To assess whether the use of adhesive radiopaque grids reduce radiation exposure in these cases. Methods: This is a cross-sectional study conducted with 23 orthopedists in which needles were positioned in a model with and without the use of adhesive radiopaque grids. The number of fluoroscopy shots necessary for proper positioning in three points (superior lateral, superior medial, and inferior medial) were registered. Results: A statistical difference was observed in the three blocking points studied. The number of radioscopies required for these three points were 12.1 ± 2.5 in the group without grid and 5.0 ± 1.8 in the group with grid. The superior medial point presented the greatest numerical difference and the inferior medial point the smallest. Conclusion: The use of adhesive radiopaque grids led to a statistically significant reduction in the number of radioscopies/fluoroscopies required to perform the genicular block. The use of this device increases the safety of the physician and patient by reducing radiation exposure in this procedure. Level of Evidence III, Level of Evidence II, Random Clinical Trial
