Epidemiology
Incidence
as high as 19 per 100,000 in U.S. (250,000 cases per year)
Uncommon in children (2% of all
Pediatric Fractures
)
Pathophysiology
Images
High energy injury (often in young adults)
Motor Vehicle Accident
Pedestrian accident
Fall from height
Toddlers and preschool children
Falls
Nonaccidental Trauma
Atypical
Femur Fracture
s
May be associated with prolonged use of
Bisphosphonates
or
Denosumab
Stop these medications if atypical
Femur Fracture
occurs
Diagnosis

Hip Fracture
Distal to first 5 cm of femoral shaft
Below
Subtrochanteric Fracture
Descriptive Classification
Proximal or distal location
Transverse or oblique angle
Comminuted (common)
Pitfalls
Associated injuries (common)
Hip Fracture
including
Femoral Neck Fracture
Supracondylar
Femur Fracture
Patella Fracture
Knee
ligament injury
Vascular Injury
Evaluate for pulseless limb or
Hemorrhagic Shock
Consider CT angiogram of leg
Imaging
See
Femur Fracture
XRay
Obtain AP and Lateral
Femur
Consider Pelvic XRay
Consider
Knee XRay
Consider
Lumbar Spine XRay
Advanced Imaging (CT, MRI)

Femur Fracture
Management
See
Trauma Evaluation
See
Femur Fracture
(includes
Hare Traction Splint
)
Immobilize hip and knee
Evaluate for associated injuries (see pitfalls above)
Strongly consider regional
Nerve Block
(
Fascia Iliaca Block
or
PENG Block
) in hip and
Femur Fracture
s
Closely manage fluid status
Initial
Resuscitation
with isotonic crystalloid
Average blood loss from
Femur Fracture
: 1.2 units
Type and Cross for 2 Units
pRBC
Continually reassess hemodynamic status
Fracture
Management (per orthopedic
Consultation
)
Age <2 years
Closed reduction and
Casting
(6-8 weeks)
Indicated if no significant angulation, rotation, comminution (otherwise surgical management)
Diaphysis
Fracture Splinting
in hip spica (hips and knees both at 90 degrees)
Age 2 to 16 years
Best management is controversial and varies by local expert opinion
Splinting
risks immobilization complications (joint rigidity, altered gait, pressure wounds)
Flexible nails and titanium elastic nails (
TENS
) may allow for growth and avoid
Splinting
complications
Age >16 years and adults
Open reduction and internal fixation (typically intramedullary rods)
Complications
Significant blood loss and hemodynamic instability
Peroneal artery and peroneal nerve injury
Associated with distal
Femur Fracture
