Title: The Analgesic Efficacy of Different Techniques Surrounding Regional Anesthesia of the Lumbar Plexus and its Terminal Branches for Hip Fracture Surgeries

Background: In 1884, the first clinical locoregional anesthetic technique was introduced, (1) followed by the first central neuraxis block just 5 years later. After another 7 decades, the first proximal lower extremity peripheral nerve block was described in 1973 called the “3-in-1 block,” (1). Since then, many techniques for regional anesthesia of the lumbar plexus and its terminal branches have evolved; including psoas compartment block (posterior lumbar plexus block), iliacus block, 3-in-1 block (anterior lumbar plexus block), PENG (pericapsular nerve group) block, etc. These techniques are frequently used for hip fracture patients due to the opioid-sparing effects, (2). However, due to the rapid pace in the development of these new techniques, confusion exists in literature and in practice regarding the definition and efficacy of one technique in comparison to another.

Research Objective: (1) To write a narrative description of regional anaesthesia approaches to the lumbar plexus and associated terminal branches; (2) To do a systematic review and meta-analysis of published articles regarding the analgesic efficacy of regional anaesthesia in the context of hip fracture and hip fracture surgery

Research Question: (1) Does regional anaesthesia of the lumbar plexus and its terminal branches enhance analgesic outcomes following hip fracture and hip fracture surgery? (2) Does the evidence point toward one techniques superiority over another?

Study Design: Quantitative systematic review and meta-analysis.
