Pediatric Femoral Shaft
Fractures
One of the most common pediatric lower
extremity fractures
Most common pediatric fracture requiring
hospital admission.
Treatment Options
Traction
Spica Casting
Pins & Plaster
External Fixation
Internal Fixation
– Plate/Screws
– Flexible nails
– Rigid Intramedullary rods - trochanteric vs. lateral entry
Pediatric Femoral Shaft
Fractures
Treatment is often directed by the
patient’s age
– 0-6 months
– 6 months - 5 years
– 5 - 11 years
– 11 years - skeletal maturity
Other considerations
– Additional injuries, social
situation, physician preference,
etc.
Femoral Shaft Fractures:
0 - 6 Months
40% of femoral diaphyseal fractures in patients <1 year of age are non-accidental
Child Abuse - approximately 15% of femoral shaft fractures in patients <36 months
of age result from abuse
>90% of pediatric femoral shaft fractures resulting from abuse occur in children <36
months of age
Femoral Shaft Fractures:
0 - 6 Months
AAOS Clinical Practice Guideline: All children < 36 months of age with a
diaphyseal femur fracture must be evaluated for child abuse
– Complete History & Physical examination
– Consultation with Pediatrician, Family Practitioner, and/or Child Abuse
Team
– Skeletal survey if warranted
•
Femoral Shaft Fractures:
0 - 6 Months
Pavlik harness
•
•
Spica casting
•
•
•
Stable union typically
achieved within 5 weeks
Higher risk of skin
complications than Pavlik
Waterproof cast liners
improve sanitation
Spica casting with
incorporated distal femoral
traction pin
•
May decrease incidence of
unacceptable shortening
and frontal plane
malalignment
•
Femoral Shaft Fractures:
6 months - 5 years
Diaphyseal Femur Fractures:
•
<2cm shortening
•
Early spica casting (90°/90°)
•
•
•
•
•
Enhanced ease of care
Shorter hospital stay
No defined optimal weight range
Spica casting in ED versus OR
yield similar reduction quality and
complication rates
Traction with delayed spica casting
•
Skin traction typically ineffective;
skeletal traction often required
Femoral Shaft Fractures:
6 months - 5 years
•
Diaphyseal Femur Fractures:
•
> 2cm shortening
•
Spica casting
•
•
•
Mode of treatment may be
altered if deemed
necessary
External fixation
•
•
Insufficient evidence to
recommend for/against
(AAOS Clinical
PracticeGuideline)
Lower incidence of
malunion compared to
spica casting
Flexible IM nailing may be
considered for the oldest, most
Femoral Shaft Fractures:
6 months - 5 years
Insufficient evidence exists to recommend any specific degree of angulation,
rotation, or shortening that is unacceptable (AAOS Clinical Practice
Guideline)
– Traditionally:
• Varus/valgus deformity more poorly tolerated than flexion/extention
deformity
• Up to 30° of rotational malunion can be tolerated
• Remodelling occurs to a greater extent in younger children with more
growth potential
• Overgrowth is a biologic response to fracture in this age group but is
unpredictable
Femoral Shaft Fractures:
5 - 11 years
Skeletal Traction
– Typically used to precede definitive treatment
particularly in severely traumatized patients
Spica casting
– Poorly tolerated,
– Higher risk of malunion
Femoral Shaft Fractures:
5 - 11 years
External Fixation
– Lower incidence of malunion than spica casting
– Ease of hardware removal compared to plates or nails
– Risk of re-fracture, pin site infection,
scarring/stiffness of IT band
– Excellent mode of provisional fixation
Femoral Shaft Fractures:
5 - 11 years
Flexible (Elastic) Intramedullary Nails
– Preferred method for treatment of most femoral
disphyseal fractures in this age group
– Titanium or stainless steel (Enders)
– Antegrade or retrograde (more common) insertion
– Outcomes best when used to treat stable fracture patterns
– Shorter hospital stay
– Fewer adverse events
– More rapid return to school
– Most common complication is irritation at distal
insertion sites
– Increased risk of poor outcome in children weighing
>108 lbs (49kg)
Femoral Shaft Fractures:
5 - 11 years
Sub-muscular plating
– Compression versus bridging plate
techniques
• Open reduction versus minimally
invasive plate osteosynthesis
(MIPO)
• May address stable or unstable
fracture patterns effectively
– Indications for plate removal remain
controversial
Femoral Shaft Fractures:
11 years - Skeletal Maturity
External Fixation
– Useful to achieve provisional fixation of femoral
fractures in severely injured patients or open fractures
– May be used for definitive treatment of subtrochanteric
or distal metadiaphyseal fractures that are less amenable
to plate or nail fixation
– Avoids direct fracture exposure, minimizes blood loss,
minimizes risk of physeal injury
– More frequent complications include delayed union and
refracture after device removal
Femoral Shaft Fractures:
11 years - Skeletal Maturity
Flexible intramedullary nails
– Outcomes optimized when use is
limited to stable fracture patterns
– Higher risk of complications in patients
>11 years of age, >108 lbs (49kg), and
unstable fracture patterns
– Commonly reported complications:
knee pain at insertion site, nail
prominence, nail migration, fracture
shortening/malunion, delayed union
Femoral Shaft Fractures:
11 years - Skeletal Maturity
Sub-muscular plating
– Compression versus bridging plate techniques
• Open reduction versus minimally invasive plate
osteosynthesis (MIPO)
• May address stable or unstable fracture patterns
effectively
• Accurate and stable reductions are achievable;
malunions uncommon
Femoral Shaft Fractures:
11 years - Skeletal Maturity
– Submuscular plating:
• Open reduction with soft-tissue
stripping fracture exposure may
increase risk of non-union
• Risk of re-fracture if plate is removed
Femoral Shaft Fractures:
11 years - Skeletal Maturity
Rigid intramedullary nailing - greater trochanteric entry femoral
nail
– Well suited for unstable fracture patterns
– Patients >108lbs (49kg) who are not candidates for
flexible IM nailing
– Piriformis or near-piriformis entry nailing is NOT a
treatment option
• Risk of injury to the lateral ascending cervical
branches of the medial femoral circumflex vessel in
the piriformis fossa
• Increased risk of femoral head osteonecrosis (≥4%)
– Risk of coxa vara due to trochanteric apophyseal growth
arrest
– Permits rapid mobilization
Femoral Shaft Fractures:
11 years - Skeletal Maturity
Femoral head osteonecrosis
Femoral Shaft Fractures:
11 years - Skeletal Maturity
Rigid intramedullary nailing- lateral entry femoral nail
– Similar indications to trochanteric entry nails
– Designed to avoid injury to circumflex vessels
and trochanteric apophysis
Pediatric Femoral Shaft
Fractures
Unable to recommend for/against removal of surgical implants from asymptomatic
patients with healed diaphyseal femur fractures (AAOS Clinical Practice
Guideline)
– Risks include refracture, hematoma, infection, scarring, etc.
Regional anesthesia is an option for perioperative care (Hematoma and/or Femoral
Nerve Block) - AAOS Clinical Practice Guideline
– Reduced narcotic administrated demonstrated with hematoma block
