Abstract

Neck of femur (NOF) and pelvic fractures are common, serious injuries encountered in the pre‑hospital setting. Both carry high morbidity and mortality and demand prompt recognition and appropriate management. This article outlines mechanisms, signs, symptoms, and treatment protocols—aligned with JRCALC and NICE (major trauma & hip fracture guidelines) to support effective and safe pre‑hospital care in the UK.

1. Introduction

NOF fractures are prevalent in older populations and carry significant short‑ and long‑term mortality and functional decline if not managed promptly. Pelvic fractures, though less frequent, can be life‑threatening due to haemorrhage risk, often due to high‑energy trauma. Early recognition and management by pre‑hospital clinicians can significantly affect outcomes.

2. Clinical Assessment in the Pre-Hospital Environment

2.1 Primary Survey

Initial assessment follows R < C > ABCDE rapidly identify catastrophic haemorrhage, airway, breathing, circulation, disability, exposure, and environmental control—before secondary survey and focused assessment of hip or pelvic injuries JRCALC

2.2 Mechanism of Injury

  • NOF: Typically low‑energy, such as a fall from standing, particularly in the elderly.

  • Pelvic fracture: Usually from high‑energy trauma (e.g. road traffic collision, fall from height), raising concern for internal haemorrhage PMCResearchGate.

2.3 Clinical Signs & Symptoms

Neck of Femur (NOF)

  • Localised pain at the groin or anterior hip, with possible referral to medial thigh or knee—beware of misdiagnosing knee pain emergencymed.org.il.

  • Leg typically appears shortened and externally rotated; movement, especially internal rotation, is painful.

  • Tenderness on palpation over the hip crease.

Pelvic Fracture

  • Pain is diffuse or central, across lower abdomen, suprapubic region, iliac crests, sacrum, buttocks, occasionally radiating to the back or perineum/genitals, not side‑specific PMCResearchGate.

  • Signs may include pelvic instability, bruising in pelvic area, or signs of shock from internal bleeding.

Physical examination must be gentle pelvic compression can worsen bleeding; avoid unless performed once and with caution. Early suspicion, based on mechanism and presentation, guides management ResearchGateFrontiers.

3. Pre-Hospital Management

3.1 Analgesia & Pain Control

NOF: Provide prompt analgesia following NICE hip fracture management (CG124)—paracetamol first; consider opioids if inadequate; nerve blocks where trained practitioners available NICE. Pre‑hospital practices often involve IV analgesia, traction splinting, or even fascia iliaca compartment block (FICB) where available emerging but effective techniques emergencymed.org.il+1.

Pelvic Fracture: Follow NICE major trauma pain guidance offer pain relief appropriate to injury severity, aiming to support patient comfort without delaying other interventions NICE.

3.2 Immobilisation & Support

NOF: Gentle handling, support, and comfort avoid unnecessary movement. Traction splinting may suit the femoral shaft but not the hip; standard practice is to immobilise the leg and minimise movement.

Pelvic Fracture: Use a purpose-made pelvic binder (or an improvised one if necessary), applied early in suspected high-energy cases to stabilise the pelvic ring and reduce haemorrhage risk NICE. Evidence supporting binders is moderate, but widely accepted as temporary stabilisation in pre‑hospital care PMC+2Royal Children’s Hospital+2.

3.3 Haemodynamic Management

Pelvic fractures carry a high risk of internal bleeding. Follow BATT score to help assess necessity for tranexamic acid (TXA); paramedics should administer TXA < 3 hours post-injury when indicated PMC. Fluid resuscitation should be judicious restrict crystalloids unless hypotensive and following local protocols.

3.4 Antibiotics

For open fractures of the femur, administer prophylactic IV antibiotics (co‑amoxiclav is common unless contraindicated), ideally within one hour of injury and without delaying transport JRCALC+1.

3.5 Transport & Destination Decisions

NOF: Generally transported to the nearest ED unless co-morbidities or other injuries necessitate a different destination.
Pelvic Fracture: If pelvic fracture is suspected and the patient stable, transport to the nearest hospital. If unstable or other major trauma criteria are present, direct transport to the Major Trauma Centre (MTC) is recommended NICE.

3.6 Ongoing Assessment & Handover

Continue monitoring vital signs, pain, and mental state en route. Provide structured handover—mechanism, signs, treatments applied (analgesia, binder, TXA), and any instability to the receiving team or trauma unit.

4. Summary Table of Key Pre-Hospital Actions

Situation Key Actions (UK Pre-Hospital)
Suspected NOF Gentle handling; analgesia (paracetamol → opioid → nerve block); immobilise; ED transport.
Suspected Pelvic Fx Treat per ABCDE; early pelvic binder; TXA if indicated; avoid internal pelvic pressure; cautious fluids; destination: ED or MTC depending on stability; urgent handover.

5. Alignment with JRCALC and NICE Standards

  • JRCALC provides essential, rolling‑update guidance for UK pre‑hospital clinicians—covering trauma assessment, analgesia, limb and open fracture management, antibiotics, etc. Magu Library+3JRCALC+3JRCALC+3.

  • NICE major trauma recommendations guide the use of pelvic binders, analgesia, triage, and pre‑hospital imaging and transfer decisions NICE.

  • NICE hip fracture guidance (CG124) emphasises early analgesia, appropriate pain control, and multidisciplinary care post‑arrival. Though focused on hospital settings, its principles bleed into pre‑hospital analgesia strategies openorthopaedicsjournal.com+3NICE+3NICE+3.

6. Discussion

NOF fractures: Frequently seen among elderly fallers; prompt analgesia and careful immobilisation are key. Pre-hospital nerve blocks (e.g. FICB) are limited but promising.

Pelvic fractures: Far riskier—bleeding and haemodynamic instability dictate urgency. Early binder application and TXA can be lifesaving. However, binders must be removed within 24 hours once the fracture is stable or controlled, coordinated with the surgical teams PMC.

7. Conclusion

Neck of femur and pelvic fractures may appear deceptively similar but require distinct approaches. NOF needs comfort, analgesia, and morbidity reduction; pelvic fracture demands vigilance for hidden bleeding, early stabilisation, and decisive transport decisions. By adhering to JRCALC and NICE guidance and keeping the focus sharp, pre‑hospital clinicians can make the difference between a manageable injury and a fatal event.
