ABSTRACT
BACKGROUND:
Minimally invasive techniques, such as percutaneous low-power laser discectomy (PLLD) and low-temperature plasma radiofrequency ablation (coblation) can be applied to treat degenerative cervical radiculopathy. However, less evidence supports the superiority of distinct minimally-invasive therapy. Our study aimed to evaluate the clinical and radiological characteristics of the PLLD and coblation for cervical radiculopathy.METHODS:
This was a prospective, multicenter, cohort study (ChiCTR-ONC-17010356). The modified Macnab criteria was performed to assess the clinical improvement pre- and post-surgery. To evaluate the radiological effect, the Pfirrmann grading system and disk herniation index were applied with MRI.RESULTS:
In this study, 28 patients were enrolled in the coblation group and 30 patients in the PLLD group. The mean good-excellent rate at 3-month follow-up was 82.1% for PLLD group, and 66.7% for coblation group, respectively (p = 0.179). The PLLD group achieved higher good-excellent rate 6 and 12 months after discharge (92.9 vs. 70.0%, p = 0.026). Radiological data revealed that PLLD but not coblation treatment achieved significant reduction of disk herniation index (p < 0.0001). Coblation treatment did not change the Pfirrmann grades of cervical radiculopathy patients (n = 18), and 7 out of 17 (41.2%) patients achieved improvement after PLLD therapy. None obvious adverse event was observed in this study.CONCLUSION:
Both PLLD and coblation are effective and safe option for patients with cervical radiculopathy. Better long-term clinical outcomes may be potentially associated with the improvement of disk degeneration after PLLD treatment.
