About this study
Official title: Comparison of the Effects of Deep Iliacus Plane Block (DIPB) and Suprainguinal Fascia Iliaca Block (SIFIB) on Postoperative Analgesia in Patients Undergoing Hip Surgery: A Randomized Controlled Study
This randomized, double-blind clinical trial aims to compare the effectiveness of the Deep Iliacus Plane Block (DIPB) and the Suprainguinal Fascia Iliaca Block (SIFIB) for postoperative pain control in patients undergoing primary total hip arthroplasty. Effective analgesia after hip surgery is essential for early mobilization, reduction of complications, and improved recovery outcomes.
Seventy patients scheduled for elective hip arthroplasty under spinal anesthesia will be randomly assigned to receive either DIPB or SIFIB at the end of surgery. Postoperative pain scores, opioid consumption, motor block, and block-related complications will be evaluated over a 48-hour period.
The study aims to determine whether DIPB provides superior or comparable analgesia with reduced motor blockade compared to SIFIB, thereby contributing to safer and more comprehensive postoperative pain management in hip surgery patients.
Read the detailed description
Hip arthroplasty is frequently associated with moderate to severe postoperative pain, which may negatively affect early mobilization, rehabilitation, and overall recovery. Adequate postoperative analgesia is therefore essential to reduce complications such as pulmonary morbidity, thromboembolism, delirium, and prolonged hospital stay.
The hip joint is innervated by both deep articular branches (femoral, obturator, and accessory obturator nerves) and superficial cutaneous branches (femoral nerve and lateral femoral cutaneous nerve). An optimal regional analgesic technique should provide effective blockade of both components. However, currently used techniques often fail to adequately block deep capsular innervation while preserving motor function.
The suprainguinal fascia iliaca block (SIFIB) is widely used in hip surgery and effectively blocks the femoral nerve and lateral femoral cutaneous nerve, providing reliable cutaneous analgesia. Nevertheless, insufficient spread to obturator and accessory obturator nerves may result in inadequate deep joint analgesia. Attempts to overcome this limitation using high-volume injections may increase the risk of quadriceps weakness and motor blockade.
The Deep Iliacus Plane Block (DIPB) is a recently described fascial plane block targeting the deep surface of the iliacus muscle at the level of the anterior inferior iliac spine. Anatomical and preliminary clinical findings suggest that DIPB allows spread of local anesthetic to femoral, lateral femoral cutaneous, and pericapsular articular branches of the hip joint, potentially providing both capsular and cutaneous analgesia with reduced motor impairment. DIPB has therefore been proposed as a hybrid technique combining advantages of existing regional blocks.
This prospective, randomized, controlled, double-blind clinical trial will be conducted at Sivas Numune Hospital. Seventy patients (ASA I-III) scheduled for elective primary total hip arthroplasty under spinal anesthesia will be enrolled and randomly assigned into two groups: the SIFIB group (n=35) and the DIPB group (n=35). Randomization will be performed using a computer-generated sequence.
All patients will receive standardized spinal anesthesia and multimodal systemic analgesia. At the end of surgery, ultrasound-guided SIFIB or DIPB will be performed by an experienced anesthesiologist using 0.25% bupivacaine (30-40 mL, weight-adjusted). Postoperative pain will be assessed using the Numeric Rating Scale (NRS) at rest and during movement at predetermined intervals up to 48 hours. Rescue analgesia with intravenous tramadol will be administered when NRS ≥4, and total opioid consumption will be recorded. Motor blockade will be evaluated using the modified Bromage scale. Block-related complications and adverse events will also be documented.
The primary aim of the study is to compare postoperative pain scores and opioid consumption between DIPB and SIFIB. Secondary outcomes include motor blockade, block-related complications, and overall analgesic effectiveness. The findings of this study are expected to clarify whether DIPB provides superior or comparable analgesia with less motor impairment, thereby contributing to safer and more comprehensive postoperative pain management in hip arthroplasty patients.

What is being measured
The primary outcome is the main question the study is designed to answer.
Postoperative pain intensity
Postoperative pain assessed using the Numeric Rating Scale (NRS; 0 = no pain, 10 = worst pain imaginable) at rest and during movement following total hip arthroplasty.
Measured: 2, 4, 8, 16, 24, and 48 hours postoperatively
Secondary outcomes (3)
Opioid consumption
Total rescue opioid consumption (intravenous tramadol) administered for postoperative pain management.
Measured: From the end of surgery to 48 hours postoperatively
Motor block
Motor blockade assessed using the Modified Bromage Scale (0-3), where higher scores indicate greater motor impairment of the lower extremity following regional anesthesia.
Measured: 4, 8, 16, 24, and 48 hours postoperatively
Pain during movement
Pain during movement assessed using the Numeric Rating Scale (NRS; 0 = no pain, 10 = worst imaginable pain), where higher scores indicate greater pain intensity.
Measured: 2, 4, 8, 16, 24, and 48 hours postoperatively

Questions about this trial
What is this clinical trial studying?
A study testing Suprainguinal Fascia Iliaca Block and Deep Iliacus Plane Block in people with Hip Arthroplasty and Postoperative Pain, run by Sivas Numune Hospital at 2 sites in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 2 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Fatih Balcı, MD (+90 545 864 76 57, fatihbalci05@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Postoperative pain intensity (time frame: 2, 4, 8, 16, 24, and 48 hours postoperatively). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07452120, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Apr 2026.
