Which Analgesia is Better for Proximal Femoral Fractures?

Not Applicable
Conditions
Proximal Femur Fracture
Interventions
Procedure: combined LFCN block with PENG block
Procedure: Fascia iliaca block
Registration Number
NCT04309539
Lead Sponsor
Mansoura University
Brief Summary

This patient population is typically elderly and frail. They are at risk of adverse effects secondary to inadequate pain management such as prolonged admissions and poor functional outcomes.

Regional analgesia is preferred due to their opioid-sparing effects and reduction in related adverse effects but The analgesia from these blocks is only moderate and literature suggests that the obturator nerve (ON) is not covered.

Detailed Description

The aim of this study is to compare the effect of combined lateral femoral cutaneous nerve block with pericapsular nerve group block versus fascia iliaca block for proximal femur surgery.

Fascia iliaca compartment block is a simple technique to manage pain before positioning for spinal anesthesia performance and it constitutes a practical choice for perioperative pain control.

A recent anatomical study confirmed the innervation of the anterior hip by these 3 main nerves, but also found that the AON and FN play a greater role in the anterior hip innervation than previously reported The high articular branches from FN and AON are consistently found between the anterior inferior iliac spine (AIIS) and the iliopubic eminence (IPE), whereas the ON is located close to the inferomedial acetabulum.

The ultrasound-guided technique for blockade of these articular branches to the hip, the PENG (Pericapsular Nerve Group) block reported significantly reduced pain scores compared with baseline. Roy et al 2019 recommended the use of PENG block together with LFCN block as adjunctive to cover the lateral surgical incision.
