Ultrasound-Guided PENG Block for Chronic Shoulder Pain

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, observational study at a single center evaluating ultrasound-guided PENG block in adults with chronic shoulder pain. Thirty-five to forty-five participants (up to 45) who have not improved with conservative care will receive a PENG block as part of routine care, using lidocaine and dexamethasone. Outcomes focus on pain and functional measures over follow-up visits, with careful screening to exclude those with bleeding disorders, active infection, recent shoulder surgery, or allergies to study medications. The study adheres to ethical standards and requires informed consent. It aims to characterize safety, feasibility, and short-term effectiveness in real-world clinical practice.
