The goal of this clinical trial is to compare Xplane ultrasound with radiography for guidance of lumbar interforamen puncture in patients with lumbar disc herniation. The main question\[s\] it aims to answer are: * The feasibility that the Xplane ultrasound assists surgeon in mastering lumbar interforamen puncture faster than radiography. * The clinical accuracy and safety of the Xplane ultrasound-guidance lumbar interforamen puncture faster. Participants will undergo lumbar interforamen puncture with guidance of Xplane ultrasound or radiography. If there is a comparison group: Researchers will compare the first success rate, number of punctures, number of radiographies, puncture time and operator confidence score.
