The use of pulsed radiofrequency (PRF) for treatment of the medial branch is controversial. ⋯ The setup of our study does not permit a comparison with the results of continuous radiofrequency (CRF) for the same procedure, other than the detection of an obvious trend. When comparing our results with various studies on CRF of the medial branch such a trend could not be found. Based on these retrospective data, prospective and randomized trials, for example, radiofrequency vs PRF are justified.
