Abstract
Pericapsular nerve group (PENG) block is a novel ultrasound (US)-guided block that is primarily used for acute pain management in the hip fractures. We report here a case where the PENG block was used for the chronic hip pain with adductor spasm due to hip osteoarthritis (OA). The PENG block with a combination of local anaesthetic and steroids provided an effective pain relief, however, only for shorter duration. After two attempts of the PENG block with local anaesthetic and steroids mixture, the pulsed radiofrequency (PRF) of the PENG was done, which provided the long-lasting relief. This report suggests that US-guided PRF of the PENG provides effective and prolonged pain relief in chronic hip pain of OA.
