For pediatric patient see Femur fracture (peds)

Background

• Despite good care, proximal fracture 30-day all cause mortality is 22% and grows to 36% at one year^[1]

Clinical Features

• History of trauma
• Pain, point tenderness, deformity

Differential Diagnosis

Femur fractures

Proximal

• Intracapsular
  • Femoral head fracture
  • Femoral neck fracture
• Extracapsular
  • Intertrochanteric femur fracture
  • Trochanteric femur fracture

Shaft

• Mid-shaft femur fracture (all subtrochanteric)

Hip pain

• Femur fracture
• Hip dislocation
• Hip bursitis
• Psoas abscess
• Piriformis syndrome
• Meralgia paresthetica
• Septic Arthritis (Hip)
• Obturator nerve entrapment
• Pelvic fractures
  • Acetabular pelvic fractures
  • Open book pelvic fracture
  • Straddle pelvic fracture
  • Pelvic avulsion fracture
• Avascular necrosis of hip

Evaluation

Proximal

Location of femur fractures

• Consider AP pelvis in addition to AP/lateral views to compare contralateral side
• Consider MRI if strong clinical suspicion but negative x-ray

Mid-Shaft

• Plain xrays of femur

Management

• Pain control in ED with femoral nerve blocks.
  • Nerve Block: Fascia Iliaca Compartment
  • 3 in 1 block (femoral, obturator, lateral cutaneous nerve of thigh)
  • No difference in 2 blocks listed above, which both reduced pain scores in the ED. ^[2]
• Most fractures, including all displaced, are treated with ORIF
  • Exception is isolated trochanteric fracture often does not require surgery
  • See individual pages for further discussion

• Type and cross/screen for patients at higher risk of hemorrhage:
  • Age > 75 yrs
  • Initial hemoglobin < 12
  • Peritrochanteric fracture

Disposition

• Generally requires admission for operative repair
