From Ionic Agitation to Precision Neuroablation: A Bioengineering Perspective on the Mechanisms, Modalities, and Clinical Applications of Radiofrequency Technology in Pain Management

Radiofrequency ablation (RFA) is a foundational interventional technology in pain management. Despite the diversity of available systems, conventional thermal, internally cooled, bipolar, and pulsed radiofrequency (PRF) all share one biophysical mechanism: high-frequency alternat...

Intrawound Vancomycin Powder in Surgical Site Infection Prophylaxis: A Comprehensive Review of Mechanisms, Efficacy, Safety, and Clinical Controversies

Surgical site infections (SSIs) remain a critical postoperative complication that causes significant morbidity, mortality, and healthcare costs. To mitigate these risks, intrawound vancomycin powder has been increasingly adopted as a prophylactic option, particularly for high-ris...
