PENG Block With or Without PPD Block for Postoperative Analgesia After Total Hip Arthroplasty
Sponsor: Kirsehir Ahi Evran Universitesi
Summary
This single-center, prospective, randomized controlled clinical trial aims to compare the postoperative analgesic efficacy of PENG block with or without posterior pericapsular deep gluteal block in adult patients undergoing elective primary total hip arthroplasty under spinal anesthesia. Total hip arthroplasty is commonly associated with moderate to severe postoperative pain. Although PENG block provides analgesia for the anterior hip capsule, some patients may still experience pain originating from the posterior capsule. The addition of PPD block may improve analgesia by targeting posterior articular branches. Participants will be randomized into two groups: one group will receive PENG block, and the other group will receive PENG plus PPD block. Postoperative pain will be assessed using the Numeric Rating Scale (NRS). The study will compare postoperative pain scores and other analgesia-related outcomes between groups.

Interventions
PENG Block
Ultrasound-guided pericapsular nerve group block performed after spinal anesthesia for postoperative analgesia in patients undergoing primary total hip arthroplasty. In Group 1, PENG block will be performed in the supine position using an in-plane technique, and 20 mL of 0.25% bupivacaine will be injected between the psoas tendon and iliopubic ramus. In both groups, lateral femoral cutaneous nerve block will also be performed as part of the analgesic protocol.
Deep posterior gluteal compartment block
Ultrasound-guided posterior pericapsular deep gluteal block performed after PENG block and spinal anesthesia for postoperative analgesia in patients undergoing primary total hip arthroplasty. In Group 2, the block will be performed in the lateral decubitus position with the hip and knee flexed to 90 degrees, and 30 mL of 0.25% bupivacaine will be injected after needle placement to the posterior acetabular rim near the ischiofemoral ligament using an in-plane technique.
