Is this trial a fit for you?
✓Likely a good fit
Adults classified ASA I–III scheduled for elective lumbar instrumentation under general anesthesia who can give informed consent and have no contraindications such as anticoagulant use, local infection, allergy to local anesthetics, diabetes, or significant renal/hepatic impairment are ideal candidates.
✕Probably not a fit
Patients on anticoagulants or with bleeding disorders, infection at the block site, pregnancy or lactation, prior lumbar surgery, diabetes, renal or hepatic impairment, or cognitive impairment limiting reliable pain reporting are unlikely to be eligible or to benefit from participation.

What this trial studies
Lumbar instrumentation commonly causes significant postoperative pain that can delay recovery and increase analgesic needs. In this interventional study, adults undergoing elective lumbar instrumentation under general anesthesia will receive an ultrasound-guided Quadro-Iliac Plane Block as part of their postoperative pain management. Investigators will record postoperative pain scores, opioid consumption, and any block-related complications to characterize analgesic effectiveness and safety. The results aim to clarify whether this newly described regional technique provides meaningful pain relief after lumbar spine surgery.
Why it matters
Potential benefit: If successful, this block could reduce postoperative pain and opioid requirements and support earlier mobilization after lumbar spine surgery.
How similar studies have gone: The Quadro-Iliac Plane Block is newly described and direct clinical data are limited, although other ultrasound-guided plane blocks for lumbar surgery have shown promising but variable reductions in pain and opioid use.
