What this trial studies

This is a prospective, monocentric observational pilot cohort enrolling adults undergoing surgery for pelvic or acetabular fractures who receive regional anesthesia within a multimodal analgesia plan. Pain intensity will be recorded at predefined time points in the first 48 hours and opioid consumption quantified in the first 24 hours, while investigators will document complications and adverse events. The team will also monitor the onset of persistent post-surgical pain and track functional recovery at 30, 60, and 90 days. Patients with absolute contraindications to regional anesthesia (for example uncorrectable coagulopathy or allergy to local anesthetics) are excluded.

Who should consider this trial

Good fit: Adults (≥18 years) with pelvic or acetabular fractures who require surgery, can provide informed consent, and have no contraindications to regional anesthesia are the ideal candidates.

Not a fit: Patients under 18, those with absolute contraindications to regional anesthesia (uncorrectable coagulopathy, known allergy to local anesthetics), or cases where regional techniques cannot be performed are unlikely to benefit from this approach.

Why it matters

Potential benefit: If successful, this approach could reduce early postoperative pain and opioid requirements and may lower complication rates and the risk of long-term persistent pain after pelvic fracture surgery.

How similar studies have performed: Regional anesthesia and peripheral nerve blocks have demonstrated reduced pain and opioid use after hip and lower-extremity fractures, but robust data specifically for pelvic and acetabular fracture surgery are limited.
