Immobilization and Splinting
›Immobilization options

›Pain reduction within 30-60 minutes expected
›Swelling considerations
›Avoid circumferential casting in early swelling phase unless specialist-directed
›Neurovascular documentation
›Pre-immobilization NV exam
›Post-immobilization NV exam
›Splint application details
›Padding and pressure control
›Extra padding at malleoli and heel
›Edge flaring to prevent skin injury
›Fit checks
›Two-finger tightness check at proximal and distal edges
›Toes visible for perfusion checks
›Post-application reassessment
›Pain trend after immobilization
›Capillary refill
›Toe movement
Reduction
›Typical need
›Reduction usually not indicated for toddler’s fracture
›Displacement uncommon
›If unexpected deformity or displacement
›Orthopedic involvement
›Alignment assessment
›Reduction plan if required
›Analgesia and sedation framework if reduction required
›Non-opioid base
›Acetaminophen PO 15 mg/kg
›Ibuprofen PO 10 mg/kg
›Opioid rescue for severe pain
›Intranasal fentanyl 1.5-2 mcg/kg
›Repeat 0.5-1 mcg/kg after 10 minutes if needed
›Maximum total per local protocol
›Procedural sedation when required
›Ketamine IV 1-2 mg/kg
›Additional 0.5 mg/kg boluses as needed
›Continuous monitoring with airway-ready team
›Ketamine IM 4-5 mg/kg if no IV access
›Redose 2-3 mg/kg if inadequate
›Recovery monitoring until baseline
›Post-procedure requirements
›NV reassessment
›Post-reduction radiographs
Open fracture medications and timing
›Open fracture pathway
›Immediate wound care
›Sterile saline-moistened dressing
›Gross contamination removal only if easily removable
›Antibiotics timing
›First dose as soon as feasible
›Antibiotic selection
›Cefazolin IV 30 mg/kg
›Maximum 2 g per dose
›If severe beta-lactam allergy, clindamycin IV 10 mg/kg
›Maximum 900 mg per dose
›If heavy contamination, broaden per local protocol and specialist guidance
›Tetanus prophylaxis
›Vaccine status verification
›Tetanus immune globulin if indicated by immunization status and wound type
›Orthopedic timing
›Urgent consultation or transfer to operative-capable center
DVT prophylaxis when relevant
›Typical pediatric case
›Pharmacologic prophylaxis not routine for isolated toddler’s fracture
›If high-risk context
›Adolescents
›Prolonged immobilization with additional risk factors
›Hematology or orthopedic guidance for prophylaxis decisions
09Special Populations/sp27
Pregnancy
›Imaging and medication considerations
›Rare scenario in pediatric condition
›Pregnant adolescent caregiver scenario not clinically relevant to injury physiology
›Radiograph shielding for caregiver presence if in room during imaging
Geriatric
›Not applicable population for toddler’s fracture
›Consider alternate diagnosis framing if presented as “spiral tibia fracture” in older patient
›Distinguish from tibial shaft fracture adult pathway
Pediatrics
›Age-specific considerations
›Typical age band 9 months to 3 years
›Low-energy mechanism common
›Occult fracture common with normal initial films
›Growth and remodeling
›Nondisplaced shaft fractures remodel well
›Malalignment uncommon in toddler’s fracture
›Nonaccidental trauma safeguards
›Higher concern in nonambulatory infants
›Child protection pathway activation triggers
›Inconsistent mechanism
›Additional bruising or injuries
›Delay in presentation
›Pediatric pain control
›Weight-based dosing
›Acetaminophen PO 15 mg/kg per dose
›Ibuprofen PO 10 mg/kg per dose if age-appropriate
›Nonpharmacologic adjuncts
›Caregiver presence
›Distraction techniques
10Background/b33
Epidemiology
›Frequency and demographics
›Common cause of limp and refusal to bear weight in toddlers
›Peak incidence during early ambulation phase
›Often no witnessed major fall
›Mechanism patterns
›Rotational injury with foot planted
›Minor trip or stumble common
›Outcomes
›Excellent healing with conservative care
›Complication rates low in nondisplaced patterns
Pathophysiology
›Injury mechanics
›Torsional force produces spiral or oblique tibial shaft fracture
›Fibula typically intact
›Why radiographs can be negative early
›Minimal displacement
›Subtle cortical lucency
›Periosteal reaction delayed
›Complications mechanism
›Skin pressure injury from immobilization
›Rare compartment syndrome
›Rare malunion in typical toddler’s fracture
Therapeutic Considerations
›Immobilization rationale
›Pain control through motion limitation
›Fracture stability support during early healing
›Immobilization choice considerations
›Long leg immobilization reduces rotation and improves comfort
›Boot may be acceptable in selected older toddlers with stable pattern and reliable follow-up
›Imaging follow-up rationale
›Repeat films show periosteal reaction confirming occult fracture
›Avoids unnecessary advanced imaging in many cases
›Evidence framing
›Conservative management standard of care for nondisplaced toddler’s fracture
›Shared decision-making for immobilization type based on comfort, safety, and follow-up reliability
11Patient Discharge Instructions/pdi23
Copy discharge instructions
›Home care and activity
›Keep splint or cast clean and dry
›Elevation above heart level as much as possible for first 48 hours
›Ice packs over splint area if tolerated
›No objects inside cast or splint
›Weight-bearing guidance
›Follow the weight-bearing plan given
›If allowed, weight-bearing as tolerated
›If not allowed, avoid standing or walking on injured leg
›Pain control plan
›Acetaminophen dosing per weight and label instructions
›Ibuprofen dosing per weight and label instructions if age-appropriate
›Avoid aspirin
›Return to ED now if
›Increasing pain not relieved by medication or elevation
›Toes become pale, blue, cold, or very swollen
›New numbness or inability to move toes
›Increasing tightness or severe discomfort under cast or splint
›Wet, broken, or slipping splint or cast
›Fever with worsening leg pain
›Follow-up
›Orthopedics or fracture clinic appointment within 3-7 days
›If initial x-rays were normal, repeat imaging may be needed in 7-10 days if still not walking
