Signs and Symptoms
- Decreased limb movement, unwilling to use
- Swelling
- Tenderness
- Deformity
- Ecchymosis
- Crepitus
- Limp
- Abnormal neurovascular status of extremity
- Compartment syndrome:
- Severe pain, especially in forearm, calf, foot
- Pain with passive stretching of fingers or toes
- Sensory deficit in the distal extremity
- Cool extremity
- Pulseless extremity
- Open fracture may be obvious or subtle (collection of blood with fat globules under skin)
History
- Mechanism of injury:
- Velocity of car, bike, etc.
- Height of fall
- Neurologic compromise
- Events surrounding injury
- Other injuries
Physical Exam
- Thorough secondary survey looking for deformities, bruising, other injuries
- Assess neurovascular status:
- Motor/sensation
- Distal pulses
- Capillary refill
- Range of motion of all joints involved
- Exclude concurrent injuries
- Ensure that history is consistent with injury
Essential Workup
- Prompt immobilization
- Imaging as below
Diagnostic Tests & Interpretation
Lab
- Required only if concomitant injuries, surgery anticipated, or multiple/major bone involvement
- CBC, ESR if infection suspected
Imaging
- Anteroposterior (AP), lateral, and oblique radiographs as necessary, including the joint above and below the fracture
- Comparison views may be useful if growth plates are involved
- Follow-up radiographs at 7-10 d may be required to exclude avascular necrosis or Salter I fractures
- Bone scan/CT/MRI may be useful to exclude fractures if plain radiographs are unhelpful or to evaluate for infection
Diagnostic Procedures/Surgery
Arthrocentesis if infection is suspected
Differential Diagnosis
- Sprain or strain
- Contusion
- Infection
- Tumor
- Neurologic deficits
- Subtle dislocations such as radial head subluxation (nursemaid's elbow)
- NAT
Prehospital
Immobilization
Initial Stabilization/Therapy
- Resuscitation for concurrent injuries
- Immobilization
ED Treatment/Procedures
- Management of life-threatening concurrent injuries
- Pain control
- Dislocations require immediate assessment and attention to neurovascular compromise:
- Mechanism helps in understand ing the direction of the force required to reduce
- Alignment is essential, particularly when fracture involves a joint surface
- Appropriate reporting of NAT
Salter-Harris Fractures
- Type I and type II fractures require immobilization and orthopedic follow-up
- Type II distal femur fractures require urgent orthopedic consultation
- Type III and type IV require urgent orthopedic consultation for anatomic reduction
- Type V fractures require immobilization and consultation
- Anatomic reduction does not eliminate possibility of growth disturbance
Clavicle Fracture
- Figure-of-8 splint or sling for comfort
- Distal third clavicle fractures should be referred with initial sling and swathe or shoulder immobilizer
Elbow Fracture
- 10% of all pediatric fractures
- >50% are supracondylar
- 10-15% have neural injury
- May present with only posterior effusion on lateral radiograph
- Orthopedic consultation because of potential neurovascular complications
- Brachial artery injury occur in 6-20% of supracondylar fractures
- Median nerve injury occur in 10-20% of supracondylar fractures
- Volar compartment syndrome of forearm can occur after supracondylar fracture:
- Develops within 12-24 hr post injury
- Can result in Volkmann ischemic contracture
- Fixed flexion of elbow, pronation of forearm, flexion at wrist, metacarpal-phalangeal joint extension
- Epiphyseal injury with long-term growth abnormalities
Distal Radius and Ulna Fractures
- Most common site of pediatric fracture: Distal radius
- Reduce angulated fractures >15 degrees
- Pronator fat pad along volar radius may indicate occult fracture
- Colles fracture:
- Reduce by traction in the line of deformity to disimpact the fragments, followed by pressure on the dorsal aspect of the distal fragment and volar aspect of the proximal fragment
- Correct radial deviation
- Immobilize wrist and elbow (sugar-tong splint)
- Orthopedic consultation
- Torus fracture (incomplete fracture; buckling or angulation on the compression side of the bone only):
- Most often in distal forearm
- Greenstick fracture (incomplete fracture of diaphysis of long bone with fracture on tension side of cortex):
- Immobilize
- Reduction if angulation >30 degrees in infants, >15 degrees in children
Tibia or Fibula Fracture
- Isolated fibular fractures: Short-leg walking cast
- Nondisplaced tibial fracture: Long-leg posterior splint, nonweight bearing
- Displaced tibial fracture and complex fractures require consultation
- Toddler's fractures:
- Nondisplaced, oblique, distal tibia fracture
- May need tangential view radiograph or bone scan to diagnose
- Splint if suspect and repeat radiograph in 7-10 d
- May apply Ottawa Ankle Rules to children
- Disruption thorough capital femoral epiphysis
- Need AP and frog-leg x-rays
- Overweight adolescent boys
- May have referred pain to knee, thigh, or groin
- Nonweight bearing with prompt orthopedic follow-up
- Often bilateral
Femur Fracture
Most common long-bone fracture
Stress Fractures
- Increasingly common
- Insidious onset
- Vague, achy pain
- Usually associated with rigorous activity
- Treatment:
- Selective bracing
- Activity modification
Open Fractures
- Irrigate and dress with moist saline gauze
- Immobilize
- Cefazolin if only small laceration and minimal contamination
- Gentamicin if moderate contamination, high-energy injury, or significant soft tissue injury
- Consider penicillin if concern for clostridia infection (farm injury, fecal or soil contamination)
- Small wounds with minimal soft tissue injury may be treated with oral antibiotics and immobilization in consultation with orthopedist
- Better prognosis than adults
Child With Limp
- Careful exam and review of systems for signs of rheumatologic disease, infection, or malignancy:
- Pediatric patients with leukemia may present with limp as their initial complaint
- CBC, ESR, CRP, arthrocentesis may be indicated
- Transient synovitis vs. septic hip
- More likely septic if:
- Fever
- Elevated ESR/CRP
- WBC elevation
- Refusal to bear weight
Medication
- Acetaminophen: 10-15 mg/kg PO or PR (per rectum) q4-6h; Do not exceed 5 doses/24 hr or 4 g/24 hr
- Cefazolin: 25-100 mg/kg daily IM/IV q8h
- Gentamicin: 2.5 mg/kg IV/IM q8h or 6.5-7.5 mg/kg IV/IM q24h
- Hematoma block: 1% lidocaine without epinephrine (max 3-5 mg/kg)
- Ibuprofen: 10 mg/kg PO q6-8h (first-line treatment)
- Morphine: 0.05-0.2 mg/kg SC/IM/IV q2-4h
Disposition
Admission Criteria
- NAT (or per social services)
- Open fracture
- Potential neurovascular compromise/compartment syndrome:
- Condylar or supracondylar humerus fracture
- Femoral shaft
Discharge Criteria
- Uncomplicated fracture: No concurrent injury or neurovascular/compartment compromise
- Follow-up arranged and parents understand injury and management
