New hip pain block could speed recovery after surgery
NCT ID NCT07453498
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two types of pain blocks for people having hip replacement surgery. One group gets a psoas sheath block, the other a standard fascia iliaca block. Researchers will measure pain, opioid use, and recovery quality in 130 adults. The goal is to see which block offers better pain relief and faster recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- psoas sheath block (local anesthetic injection)
- What this could lead to
- If it works, this could provide better pain control and faster recovery after hip replacement surgery.
- What could go wrong
- This is a small, early-stage trial comparing two similar procedures, so the difference may be small or not clinically meaningful. Results may not apply to all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Participants aged \>18 * Patients scheduled to undergo elective unilateral total hip replacement (THR) surgery. * Patients who agree to receive regional anaesthetic blocks as part of their post-operative pain management. * Physical Status: ASA (American Society of Anesthesiologists) physical status classification I-III. * Patients who are willing and able to provide informed consent, demonstrating an understanding of the trial's purpose, methods, and potential risks. * Patients who are willing to comply with assessments post-surgery Exclusion Criteria: * Allergy to Study Medications * History of chronic opioid use (\>50mg of oral morphine equivalents per day. * Any neurological condition affecting the lower extremities (e.g., peripheral neuropathy, radiculopathy) that could interfere with pain assessment or recovery evaluation. * Infection at Injection Site * Coagulopathy or Anticoagulant Use: Patients with coagulopathy (INR \>1.5) or who are on anticoagulant therapy that cannot be safely discontinued for the block procedure. * Severe Respiratory or Cardiovascular Disease: Any severe respiratory or cardiovascular disease (e.g., severe chronic obstructive pulmonary disease, heart failure) that may increase perioperative risk and complicate recovery. * Cognitive impairment or conditions (e.g., dementia with MMSE \<24) that would prevent reliable pain reporting or compliance with post-operative assessments
