Abstract:

Objective To observe the feasibility and accuracy of ultrasound-guided transforaminal epidural injection.Methods Ultrasound-guided injection at L1-2, L2-3, L3-4, L4-5, L5-6 bilaterally was performed in L1-6 spine from two Bama miniature pigs. The position of needles was detected with X-ray and CT, and observed under anatomy. The distance from the puncturing points at skin to the posterior midline, the depths and angles of puncturing between were measured and compared bilaterally.Results The successful rate was 95% (19/20), out of which, 80% (16/20) were put the needle tips at the lower part of the intervertebral foramen, ventral side, central region or paracentral region. There was no significant difference between sides in the distances, depths or angles in 19 successful injections.Conclusion It is accurate to transforaminally puncture under ultrasound-guided.

Key words: transforaminal epidural injection, ultrasound-guided, pigs
