Ultrasound guided pericapsular nerve group (PENG) block resulting in reduction of dislocated prosthetic hip

Abstract

A 78-year-old woman with a prosthetic hip dislocation underwent a pericapsular nerve group block for regional anesthesia. The hip spontaneously reduced before manual intervention, likely due to the block's analgesic and muscle-relaxing effects. Compared to other techniques, this block effectively targets hip innervation while sparing motor function. This case highlights its potential for managing hip dislocations safely, especially in patients at risk from sedation.
