The intra- and peri-articular infiltration of local anaesthetics realized at the end of total hip arthroplasty surgeries is an effective analgesic technique, but it can be insufficient to manage the possibly intense postoperative pain. Regional anaesthesia (RA) like the recently described pericapsular nerve group (PENG) block could provide additional analgesic benefit in this setting.
Investigators main objective is to demonstrate the analgesic benefits (postoperative pain score and morphine consumption) of the PENG block when added to intra- and peri-articular infiltration of local anaesthetic following total hip arthroplasty. Investigators make the assumption that i) the PENG bloc could reduce the postoperative 24 first hours morphine consumption by 30%, ii) the PENG block could spare the motor function of the quadriceps and adductor muscles, and iii) the PENG bloc could be well tolerated allowing a high level of patient satisfaction.
A recent study has revealed a region of pericapsular terminal branches of the femoral nerve and the obturator nerve accessible to ultrasound-guided regional anaesthesia. This technique, also called the PENG block, has recently been described with a substantial benefit on pain at rest and induced by mobilization in cases series of patients undergoing hip fracture surgery. To investigators knowledge, no randomized data concerning the analgesic efficacy of the PENG block has been published in the setting of elective total hip arthroplasty.
The PENG block would allow a significant analgesic contribution when added to intra- and peri-articular infiltration of local anaesthetics while being well tolerated with few undesirable effects. Moreover, the PENG block could spare the motor function of the quadriceps and adductor muscles allowing enhanced recovery after surgery

| ultrasound-guided PENG bloc realized before surgery | Procedure | ultrasound-guided PENG block realized before surgery. The PENG block, described by Giron-Arebgi is made in the supine position. The ultrasound probe used is a 5 MHz high frequency linear probe placed parallel to the line delimited by the anterior-inferior iliac spine (lateral) and the pubis (medial). The needle used is an 80 mm, 22G, needle inserted in the ultrasound plane. The slow and fractioned injection of 20 ml of Ropivacaine 4.75 mg/ml is performed in the fascia between the psoas tendon and the iliopubic eminence under ultrasound guidance. |
