Cite This Study

Cosman et al. (1984) reported a review. Radiofrequency (rf) lesion making in the dorsal root entry zone (DREZ) was evaluated. Radiofrequency lesion making in the dorsal root entry zone requires careful temperature monitoring and stable electrode penetration to achieve consistent and safe results.
