Summary

This study aims to investigate the efficacy of adding a Posterior Pericapsular Deep gluteal block to two other standard nerve blocks-the Pericapsular Nerve Group block and the Lateral Femoral Cutaneous Nerve block-for patients undergoing orthopedic hip surgery. While standard blocks target the front of the hip, many patients still feel pain in the back (posterior) of the joint. Researchers will compare two groups of patients to see if this triple-block combination provides better pain relief and reduces the need for rescue opioid medications in the 24 hours following surgery.

Detailed description

Patients undergoing elective orthopedic hip surgery will be randomly assigned to one of two groups. Both groups will receive general anesthesia followed by ultrasound-guided nerve blocks. Group 1 will receive a Pericapsular Nerve Group block and a Lateral Femoral Cutaneous Nerve block using 0.25% bupivacaine. Group 2 will receive these same two blocks plus an additional Posterior Pericapsular Deep gluteal block, also using 0.25% bupivacaine. The primary goal is to evaluate postoperative pain using the Numerical Rating Scale at 6, 12, and 24 hours for both static and dynamic states. Secondary objectives include assessing quadriceps muscle strength using the Lovett Grading Method, measuring total rescue analgesia (nalbuphine) consumption, and monitoring for any complications or differences in length of hospital stay.

Conditions

• Postoperative Pain
• Hip Osteoarthritis
• Hip Fractures

Interventions

Type	Name	Description
PROCEDURE	Posterior Pericapsular Deep Gluteal, Pericapsular Nerve Group, and Lateral Femoral Cutaneous Nerve Blocks.	Under ultrasound guidance, patients receive a Pericapsular Nerve Group block, a Lateral Femoral Cutaneous Nerve block, and a Posterior Pericapsular Deep gluteal block. For each of the three blocks, 10-15 ml of 0.25% bupivacaine is injected while observing for adequate fluid spread over the respective anatomical targets.
PROCEDURE	Pericapsular Nerve Group and Lateral Femoral Cutaneous Nerve Blocks.	Patients receive ultrasound-guided Pericapsular Nerve Group and Lateral Femoral Cutaneous Nerve blocks with 10-15 ml of 0.25% bupivacaine for each block.
