Pericapsular Nerve Group (PENG) Block for Congenital Hip Dislocation Surgery

Pericapsular Nerve Group (PENG) Block for Congenital Hip Dislocation Surgery: Randomized Controlled Double Blind Study

Developmental dysplasia of the hip (DDH) is one of the major disorder of the pediatric population with an incidence of 3 to 5 per 1000 children. Open surgical reduction of congenital hip dislocation (CHD) is typically performed after an ineffective closed reduction or older than 18 months. Multiple femoral or pelvic osteotomies and tenotomies are performed during this surgical treatment and cause severe postoperative pain. Pericapsular nerve group (PENG) block has been recently recommended for use as postoperative analgesia in hip surgeries. It is a new regional anesthesia method based on blocking the articular branches of femoral nerve (FN) and accessory obturator nerve (AON) in the region between the anterior inferior iliac spine (AIIS) and iliopubic eminence (IPE).The aim of this study was to evaluate the analgesic effect of ultrasound guided pediatric pericapsular nerve group (PENG) block in pediatric patients undergoing CHD surgery.
