Background/aim: We investigated the short-and medium-term effectiveness of genicular nerve radiofrequency (RF) applied in patients with chronic knee pain due to osteoarthritis. Materials and methods:Radiofrequency was performed in 49 patients with a diagnosis of knee osteoarthritis. VAS and WOMAC were measured at baseline and at 1, 4, and 12 weeks postprocedure. Under fluoroscopic guidance, the cannula was advanced percutaneously towards the area connecting the shaft to the epicondyle. The RF electrode was inserted through the cannula and the electrode tip temperature was raised to 80 °C for 90 s. One RF lesion was made for each genicular nerve.

SummaryObjectives: The aim of this study was to evaluate the efficacy of greater occipital nerve (GON) block in the treatment of migraine patients.Methods: This study included 28 patients diagnosed with migraine between 2014 and 2015. The GON block procedure was applied by administering 1.5 ml of 2% lidocaine 2 cm lateral and 2 cm inferior to the external occipital protuberance. The patients were evaluated in respect of VAS scores, attack frequency, attack duration and the need for analgesia before the procedure. These parameters were evaluated again at 1 week, 1 month and 3 months after the procedure. Results:The mean age of the patients was 42.21±10.13 years. The mean VAS score was 9.28±0.72 before the procedure and 2.96±2.16 at 1 week, 2.60±1.96 at 1 month and 1.75±1.37 at 3 months. The frequency of attacks was 9.42±4.51 before the procedure and, 5.42±3.30 at 1 month and 3.57±3.14 at 3 months.Conclusion: GON block with 1.5 ml of 2% lidocaine is a safe, simple and effective treatment method for migraine headache.Keywords: Greater occipital nerve block; lidocaine; migraine.
