About this trial
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.

Treatments tested in this trial
PENG Block
Procedure/SurgeryUltrasound-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
Procedure/SurgeryUltrasound-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.

Trial outcomes
Primary outcomes
1
Postoperative pain intensity at 6 hours measured by Numeric Rating Scale (NRS)
Postoperative pain intensity will be assessed using the Numeric Rating Scale (NRS), where 0 indicates no pain and 10 indicates the worst imaginable pain. The primary comparison between groups will be the NRS score at postoperative 6 hours
Time frame
6 hours after surgerySecondary outcomes
1
Postoperative pain intensity over the first 24 hours measured by Numeric Rating Scale (NRS)
Postoperative pain intensity will also be assessed in the recovery room and at postoperative 2, 12, and 24 hours using the Numeric Rating Scale (NRS)
Time frame
Recovery room, 2 hours, 12 hours, and 24 hours after surgery2
Total analgesic consumption during the first 24 hours
Total amount of analgesic medication consumed within the first 24 hours after surgery will be recorded and compared between groups
Time frame
24 hours after surgery3
Time to first rescue analgesic requirement
Time from block performance to first additional analgesic requirement will be recorded
Time frame
Up to 24 hours after surgery4
Time to first mobilization
Time to first standing or mobilization after surgery will be recorded and compared between groups
Time frame
Up to 24 hours after surgeryLocations
