›CRP for suspected septic arthritis or osteomyelitis

›Elevated values support inflammation

›ESR for suspected septic arthritis or osteomyelitis

›Elevated values support inflammation

›Blood cultures if febrile with concern for bacteremia

›Obtain before antibiotics when feasible

06Diagnostic Tests/dt27

Scoring Systems

›Clinical decision support

›No validated scoring system specific to radial head subluxation

›Diagnosis primarily clinical in typical cases

›Imaging threshold framework

›If swelling, deformity, focal bony tenderness, or atypical mechanism, radiographs before reduction

MRI

›Advanced imaging role

›Rare indications

›Persistent pain and dysfunction with normal radiographs

›Concern for occult fracture, ligament injury, or infection

›Limitations

›Sedation needs in young children

›Not first-line in ED setting

›CT role

›Not routine for suspected radial head subluxation

›Radiation risk outweighs benefit

›Possible indication

›Complex fracture assessment when radiographs inadequate and orthopedic team requests

Ultrasound

›Point-of-care ultrasound adjunct

›Potential findings

›Annular ligament displacement

›Radial head alignment changes

›Use cases

›Equivocal cases with low suspicion of fracture

›Reduction confirmation when clinical reassessment uncertain

›Limitations

›Operator dependence

›Normal study does not exclude fracture

07Disposition/dispo17

Discharge criteria and follow-up

›Discharge after successful reduction

›Return of spontaneous use of arm

›Typical within 5-15 minutes

›Occasionally up to 30-60 minutes in anxious child

›Normal distal neurovascular status

›Caregiver education on recurrence prevention

›Observation or reassessment pathway

›If function not returning by 30-60 minutes, imaging for fracture or alternate diagnosis

›If radiographs normal and still not using arm, immobilization and close follow-up

Admission and consultation

›Orthopedic consultation triggers

›Failed reduction after 2-3 well-performed attempts

›Suspicion of fracture or dislocation

›Neurovascular compromise

›Concern for non-accidental trauma injury pattern

›Admission triggers

›Suspected septic arthritis or osteomyelitis requiring IV antibiotics

›Uncontrolled pain with suspected significant injury

08Treatment/t57

Analgesia and comfort

›Comfort measures

›Caregiver presence

›Minimize restraint when possible

›Distraction techniques

›Toys, video, bubbles

›Analgesics

›Acetaminophen PO 15 mg/kg per dose

›Maximum 1000 mg per dose

›Maximum 60 mg/kg/day or per local policy

›Ibuprofen PO 10 mg/kg per dose

›Maximum 600 mg per dose

›Avoid if dehydration, renal disease, or bleeding risk

›Intranasal fentanyl 1.5 microg/kg if severe pain or significant anxiety

›Maximum per local protocol

›Monitoring for sedation and respiratory depression

›Sedation considerations

›Procedural sedation usually unnecessary for typical reduction

›Consider only if repeated attempts and severe distress, and fracture has been excluded

Reduction maneuvers

›Technique selection

›Hyperpronation method

›Higher first-attempt success reported in comparative studies

›Less painful in many children

›Supination-flexion method

›Widely used alternative

›Useful if hyperpronation fails

›Hyperpronation maneuver

›Setup

›Stabilize elbow with thumb over radial head

›Hold distal forearm

›Motion

›Rapid forearm pronation

›Optional gentle elbow flexion at end range

›Success indicators

›Palpable or audible click at radial head may occur

›Supination-flexion maneuver

›Setup

›Stabilize elbow with thumb over radial head

›Hold distal forearm

›Motion

›Rapid forearm supination

›Immediate elbow flexion

›Success indicators

›Click may occur at radial head

›Post-reduction reassessment

›Functional recovery

›Child reaches for toy or uses hand

›Repeat attempt pathway

›If no improvement after 10-15 minutes, second attempt with alternate technique

›If still no improvement, radiographs

Immobilization and aftercare

›After successful reduction

›No routine splinting

›Normal use expected

›If persistent symptoms with normal imaging

›Posterior long-arm splint

›Elbow 90 degrees

›Forearm neutral or per comfort

›Follow-up within 24-72 hours with primary care or orthopedics

09Special Populations/sp27

Pregnancy

›Pregnancy considerations

›Condition rare in pregnant patients as primary population is pediatric

›Apply general limb injury assessment if adult presentation

›Imaging choice if adult elbow injury

›Radiographs acceptable with shielding when clinically indicated

›Analgesia

›Acetaminophen preferred

›NSAID avoidance guidance based on gestational age and local policy

Geriatric

›Older adult considerations

›Radial head subluxation uncommon

›Higher likelihood of fracture or dislocation with similar symptoms

›Lower threshold for imaging

›Osteoporosis risk

›Neurovascular assessment priority

›Baseline neuropathy confounders

Pediatrics

›Pediatric-specific approach

›Typical age range

›Most common in 1-4 years

›Can occur from infancy through early school age

›Weight-based analgesia

›Use kg dosing

›Recurrence counseling

›Avoid traction on arms

›Teach safe lifting under armpits

›Non-accidental trauma screen

›Inconsistent history

›Multiple bruises or injuries at different stages

10Background/b26

Epidemiology

›Epidemiologic features

›Common pediatric upper limb injury in toddlers

›Peak incidence in early childhood

›Recurrence

›Recurrence can occur, especially after first episode

›Laterality patterns

›Either arm possible

Pathophysiology

›Mechanism

›Annular ligament displacement over radial head

›Longitudinal traction on pronated forearm

›Pediatric anatomy predisposition

›Smaller radial head

›More lax annular ligament in early childhood

Therapeutic Considerations

›Reduction rationale

›Restores annular ligament position

›Rapid symptom resolution expected

›Imaging rationale

›Typical cases are clinical diagnosis

›Atypical features increase fracture probability

›Technique choice rationale

›Hyperpronation often higher success on first attempt

›Consider as first-line

›Alternate technique reasonable if first attempt fails

›Guideline style evidence framing

›Clinical pathway consensus supports reduction without imaging in classic presentation (ACEP Level C style consensus)

›Hyperpronation as first-line reasonable (Class IIa style recommendation based on comparative trials and systematic reviews)
