Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you must not be taking opioids regularly before joining. If you are on opioids, you may need to stop them to participate.

What data supports the effectiveness of the treatment Fascia Iliaca Nerve Block and Pericapsular Nerve Block for hip osteoarthritis?

Research shows that both Fascia Iliaca and Pericapsular Nerve Blocks are effective in reducing pain and improving comfort in patients with hip fractures and during hip surgeries. These treatments help decrease the need for opioids (strong painkillers) and improve patients' ability to move comfortably, which suggests they could be beneficial for hip osteoarthritis as well.12345

Is the nerve block treatment for hip osteoarthritis safe?

Nerve blocks like the fascia iliaca and pericapsular nerve group blocks have been used in hip surgeries, but they can cause decreased strength in the quadriceps (thigh muscles) and increase the risk of falls. These blocks are generally safe but may not be recommended for routine use due to these side effects.12356

How is the Fascia Iliaca Nerve Block and Pericapsular Nerve Block treatment different from other treatments for hip osteoarthritis?

The Fascia Iliaca Nerve Block and Pericapsular Nerve Block are unique because they target specific nerves around the hip joint to relieve pain, potentially reducing the need for opioids and their side effects. These blocks are guided by ultrasound, which helps in precisely targeting the nerves responsible for hip pain, making them a novel approach compared to traditional pain management methods.12357

What is the purpose of this trial?

In order to continue progressing towards outpatient total hip arthroplasty (THA), methods to adequately manage postoperative pain is of paramount importance. The purpose of this study is to quantify the effectiveness of the pericapsular nerve block in total hip arthroplasty in comparison to the fascia iliaca nerve block.

Eligibility Criteria

This trial is for adults planning to undergo primary total hip arthroplasty using the anterior approach, with an ASA score of 1-3, and who have not been taking opioids. They must be willing to follow study procedures and provide consent. Excluded are those with general anesthesia during surgery, certain conditions like ankylosing spondylitis or chronic pain, opioid tolerance, or allergies to medications used in the nerve blocks.

Inclusion Criteria

Treatment Details

Interventions

  • Fascia Iliaca Nerve Block
  • Pericapsular Nerve Block
Trial Overview The study compares two types of nerve blocks for managing postoperative pain after hip replacement surgery: pericapsular nerve block versus fascia iliaca nerve block. The goal is to determine which method better supports outpatient recovery by effectively controlling pain.
Participant Groups
2Treatment groups
Active Control
Group I: Fascia Iliaca Nerve Block GroupActive Control1 Intervention
Fascia Iliaca Nerve Block targets the space between the iliacus muscle and the fascia that overlies it (fascia iliaca), within which the femoral nerve and lateral femoral cutaneous nerve (LFCN) course.
Group II: Pericapsular Nerve Block GroupActive Control1 Intervention
Pericapsular Nerve Block targets the anterior hip capsule by blocking the articular branches of the femoral nerve and accessory obturator nerve.

Findings from Research

In a study of 40 patients undergoing total hip arthroplasty, the pericapsular nerve group block significantly reduced the incidence of quadriceps motor block at 3 hours (45% vs 90%) and 6 hours (25% vs 85%) compared to the suprainguinal fascia iliaca block, indicating better preservation of motor function.
Both techniques showed similar outcomes in terms of postoperative pain, opioid consumption, and ability to perform physiotherapy, suggesting that while the pericapsular nerve group block is more effective in preserving motor function, it does not compromise overall pain management or recovery.
Randomized comparison between pericapsular nerve group (PENG) block and suprainguinal fascia iliaca block for total hip arthroplasty.Aliste, J., Layera, S., Bravo, D., et al.[2022]
In a study of 384 patients undergoing hip surgery, the Pericapsular Nerve Group (PENG) block was found to significantly reduce static pain scores at 12 hours post-surgery and decrease opioid consumption in the first 24 hours compared to the Fascia Iliaca compartment (FI) block.
However, there were no significant differences in pain scores at 6 or 24 hours post-surgery or in the time to first analgesic rescue between the two techniques, indicating that while PENG may offer some immediate benefits, further research is needed to fully understand its advantages over FI block.

Patients with higher preoperative psychological distress were more likely to request a fascia iliaca nerve block for pain control after hip arthroscopy, with 70% of distressed patients requesting it compared to only 36% of those with normal distress levels.
The fascia iliaca nerve block significantly improved pain management, as patients who received the block showed a greater reduction in pain scores by discharge from the post-anesthesia care unit compared to those who did not receive the block.
