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 Fracture Types
Proximal
- Intracapsular
- Extracapsular
Shaft
- Mid-shaft femur fracture (all subtrochanteric)
Hip pain
Acute Trauma
- Femur fracture
- Proximal
- Intracapsular
- Extracapsular
- Shaft
- Mid-shaft femur fracture (all subtrochanteric)
- Proximal
- Hip dislocation
- Pelvic fractures
Chronic/Atraumatic
- Hip bursitis
- Psoas abscess
- Piriformis syndrome
- Meralgia paresthetica
- Septic arthritis
- Obturator nerve entrapment
- Avascular necrosis of hip
Diagnosis
Proximal
- 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 pts at higher risk of hemorrhage:
- Age > 75 yrs
- Initial Hb < 12
- Peritrochanteric fracture
Disposition
- Generally requires admission for operative repair
