PURPOSE: Currently, minimally invasive intervention surgery for cervical spondylotic radiculopathy mostly involves the use of cervical dorsal root ganglion (DRG) block or radiofrequency modulation therapy. Here, we proposed a novel transverse ultrasound-guided approach for puncturing the cervical dorsal root ganglion at the level of joint column for radiofrequency treatment.
PATIENTS AND METHODS: A retrospective analysis of the clinical data of 30 patients with cervical spondylotic radiculopathy admitted to the Pain Department of Taihe Hospital Affiliated with Hubei Medical University from January 2021 to March 2024 was performed. During surgery, motor electrical stimulation was used to induce movement in the nerve-innervated area, and the relationship between the puncture needle tip and the cervical DRG position was verified using a C-arm X-ray machine. The numerical rating scale (NRS) was used for preoperative and postoperative pain assessment, clinical treatment effectiveness was evaluated, surgical duration and the associated complications were also recorded.
RESULTS: Thirty patients exhibited clear cervical DRG images under ultrasound guidance, and the punctures were successful in all patients. Motor electrical stimulation induced movement in the corresponding nerve innervation area in the range of 0.3-0.8 mv in all patients. No serious complications occurred during the procedure.
CONCLUSION: The transverse ultrasound-guided approach for puncturing the cervical dorsal root ganglion at the level of joint column for radiofrequency treatment is effective, convenient, and safe.
