Pulsed radiofrequency (PRF) is a commonly used, minimally invasive method to treat herpes zoster neuralgia, but the intensity of standard voltage PRF is limited, resulting in patients not getting a lasting therapeutic effect. The therapeutic effect of repeated high-voltage long-duration PRF on acute herpes zoster neuralgia has not been studied. ⋯ Repeated high-voltage long-duration PRF therapy was an effective treatment for acute herpetic neuralgia and may prevent the occurrence of PHN.

Recurrent LDH (rLDH) is one of the most common causes of unsatisfactory outcomes after discectomy, which usually needs secondary surgery and leads to physical and psychological suffering for patients and substantial costs for society. ⋯ This study demonstrated that the recurrence rate of LDH at 5-year follow-up was 6.27% and there was a significant statistical relationship between FO, DHI, and Modic changes and early rLDH. Surgeons should take FO angles, DHI, and Modic change into consideration before surgery to achieve a satisfactory postoperative outcome and a relatively lower early recurrence rate. More patients and further investigation should be taken to assess the risk factors for early rLDH.
