Letter to the Editor: 3D CT visualization of injectate spread following femoral and obturator nerve articular branches radiofrequency - An anatomical contribution to our previous findings.

In our previous study, radiofrequency (RF) thermocoagulation of femoral and obturator articular branches was shown to provide superior outcomes in chronic hip pain compared with pericapsular nerve group block and intra-articular steroid injection. Here, we present a complementary case in which three-dimensional computed tomography (3D CT) was used to visualize injectate spread following RF. Imaging demonstrated localized distribution at the articular branch level of both nerves, without main trunk involvement. These findings provide anatomical confirmation of dual nerve coverage and suggest that 3D CT may enhance understanding of procedural efficacy.
