Pain management is a crucial aspect of the care of hip fracture patients. Patients with poorly controlled pain have an increased risk of delirium, long-term functional impairment, and remain hospitalized longer. Today, to relieve hip fracture pain, fascia iliaca block is routinely performed in the emergency department in addition to other pain medications administered by vein or by mouth. Several studies have questioned the analgesic efficacy of this block, suggesting the superiority of the newer PENG block. The purpose of this multicenter, randomized study is to compare the analgesic efficacy of PENG block versus fascia iliaca block, hypothesizing the superiority of the new approach over the gold standard. Participants will be blindly assigned in a 1:1 ratio to the study or control group, recruited from the Emergency Departments of IRCCS Policlinico San Matteo and Colchester Hospital (UK).
The main outcome is represented by the reduction of pain after the two blocks, measured as %SPID (percentage of "pain intensity difference"), a value derived from VAS scale measurements in the first hour post-procedure. Secondly, we will evaluate the proportion of patients with satisfactory pain control, the amount of opioids used and the safety profile of the two approaches.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| PENG block: Study group | Experimental | Patients enrolled in the study group will receive a PENG block with 20 mL of 0,375% levobupivacaine with 4 mg of dexamethasone. The block will be performed with the patient in a supine position using an 18-gauge, 90 mm needle, inserted with an in-plane lateral to medial approach. Operators will use the original technique described by Girón-Arango L et al. The aim of this block is to inject the local anaesthetic between the psoas tendon and the iliopubic eminence. We will instruct operators to routinely use a curvilinear probe (2-6 MHz) or a linear probe (4-16 MHz) in particularly lean or cachectic patients. |

| Infrainguinal fascia iliaca block: Control group | Other | Patients allocated in the control group will receive an infrainguinal fascia iliaca block with 30 mL of 0,25 % levobupivacaine with 4 mg of dexamethasone, using an 18-gauge, 90 mm needle, inserted with an in-plane lateral to medial approach. The probe (linear 4-16 MHz) is placed transversely at the inguinal crease to identify the femoral artery, femoral nerve, iliopsoas muscle and the fascia iliaca over the psoas muscle. Moving the probe laterally the sartorius muscle and the anterior inferior iliac spine (AIIS) can be identified. After skin disinfection the needle is inserted placing the tip beneath the fascia iliaca at the lateral third of a line between the AIIS and pubic tubercle. Correct needle placement is confirmed by separation of the fascia iliaca from the iliopsoas muscle upon injection, with local anaesthetic spreading towards the FN medially and the iliac crest laterally. |

andomised-controlled trial with two parallel study groups. Participants will be randomised 1:1 to the study or control group. The study group will be treated with PENG block following randomisation, whereas the control group will receive the standard treatment, i.e., fascia iliaca block.
The study aims to demonstrate the superiority of the new intervention over the standard approach.
