Diagnosis

[Section Outline]

Signs and Symptoms!!navigator!!

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!!navigator!!

Diagnostic Tests & Interpretation!!navigator!!

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

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

Slipped Capital Femoral Epiphysis

  • 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

Follow-Up

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

Issues for Referral

All Salter-Harris fractures should have orthopedic follow-up

Pearls and Pitfalls

  • History is essential in evaluation of NAT
  • Undress patient fully especially if suspicion for NAT
  • Have a low threshold to splint and /or consult orthopedist
  • Pain control is essential and often underdosed
  • Distal radius is often associated with other fractures: Ulna, elbow, carpal bones
  • Supracondylar fractures may lead to nerve or vascular injury
