In patients who benefit from the diagnostic block-defined as a reduction of 50% or more in VAS scores following the procedure-pulsed radiofrequency (PRF) treatment is added as a second-stage intervention. This stepwise approach reflects standard clinical practice, and both procedures are commonly used in clinical praqctice for the management of chronic hip pain. However, the available evidence in the literature on this approach is largely limited to case reports and retrospective case series.

In the first stage, all patients undergo an ultrasound-guided pericapsular nerve group (PENG) block as a diagnostic and therapeutic procedure. Pain intensity is assessed using the Visual Analog Scale (VAS) following the diagnostic block. Only patients who demonstrate a clinically meaningful response, defined as a reduction of 50% or greater in VAS scores, proceed to the second stage of the intervention.\n\nIn the second stage, pulsed radiofrequency (PRF) treatment is applied to the same target region in addition to the PENG block, aiming to achieve longer-lasting analgesia through neuromodulation without tissue destruction.",[9],[21],{"name":22,"role":23,"phone":24,"phoneExt":10,"email":25},"Ulku Sabuncu MD, Assoc. prof.","CONTACT","+905337085212","sabuncuulku@gmail.com",[27],{"facility":28,"status":29,"city":30,"state":10,"zip":31,"country":32,"countryCode":10,"cosmosGeoPoint":33,"geoPoint":38,"contacts":39},"Ankara Bilkent City Hospital","RECRUITING","Ankara","06680","Turkey (Türkiye)",{"type":34,"coordinates":35},"Point",[36,37],32.85427,39.91987,{"lat":37,"lon":36},[40],{"name":41,"role":23,"phone":42,"phoneExt":10,"email":10},"Ulku Sabuncu Assoc.
