Ortho follow-up if stable after reduction or if managed nonoperatively
Admission if uncontrolled pain
Transfer criteria
Posterior dislocation without surgical backup
Any vascular compromise concern
Any airway compromise concern
Follow-up timing
Outpatient follow-up targets
Orthopedics within 3 to 7 days for anterior injury
Earlier follow-up if reduction performed in ED
Rehab plan after immobilization period
Treatment
Immediate life-saving interventions
Posterior dislocation emergency actions
If airway compromise, airway team activation
If hemodynamic instability, hemorrhage protocol and surgical activation
If vascular compromise, emergent reduction planning with vascular surgery availability
Analgesia baseline
Acetaminophen PO 1000 mg
Ibuprofen PO 400 mg
If opioid required, morphine IV 0.05 mg/kg
Nausea control when sedation anticipated
Ondansetron IV 4 mg
If QT concern, metoclopramide IV 10 mg
Immobilization and Splinting
Immobilization strategy
Sling for comfort
Shoulder girdle support to limit motion
Avoid circumferential chest binding if respiratory compromise risk
Post-immobilization checks
Neurovascular recheck
Symptom recheck for dyspnea and dysphagia
Reduction
Reduction indications
Posterior dislocation suspected
Neurovascular compromise
Airway or esophageal compression symptoms
Skin compromise
Reduction location and team
Posterior dislocation reduction with surgical standby
Anterior dislocation reduction acceptable in ED if stable and experienced team
Analgesia and anesthesia
Local and regional options
Local infiltration at SC region avoided if anatomic distortion or vascular concern
Regional anesthesia considered per local expertise
Procedural sedation pathway
Airway risk assessment
Posterior dislocation treated as potential difficult airway
NPO status not required for emergent reduction
Sedation medication options
Ketamine IV
Initial 1 mg/kg
If inadequate, additional 0.5 mg/kg
Propofol IV
Initial 0.5 mg/kg
Titrate 0.25 mg/kg every 1 to 3 minutes to effect
Fentanyl IV for analgesia adjunct
0.5 mcg/kg
Repeat 0.5 mcg/kg every 5 minutes as needed
Anterior dislocation technique principles
Supine position with towel roll between scapulae
Traction on abducted arm
Direct pressure posteriorly on medial clavicle
Posterior dislocation technique principles
Operating room preferred
If emergent bedside attempt, surgical team present
Shoulder abduction and traction with extension
Towel clip technique reserved for operative setting
Post-reduction requirements
Repeat neurovascular exam
Repeat airway symptom check
Post-reduction CT confirmation for posterior dislocation
Immobilization plan and activity restriction
Open fracture medications and timing
Skin breach pathway relevance
Open injury uncommon at SC joint
If open wound present, open fracture protocol
Antibiotics if open injury
Cefazolin IV 2 g
If severe beta-lactam allergy, clindamycin IV 600 mg
Tetanus prophylaxis
Tdap if immunization unknown or not up to date
Tetanus immune globulin if high-risk wound and unimmunized
DVT prophylaxis when relevant
DVT prophylaxis considerations
Upper extremity immobilization alone usually no pharmacologic prophylaxis
If polytrauma admission, follow institutional VTE protocol
Special Populations
Pregnancy
Pregnancy considerations
Shielding for radiographs when feasible
CT use guided by maternal benefit and injury severity
Acetaminophen preferred analgesic
Sedation considerations
Obstetrics consultation if viable gestation and procedural sedation planned
Left lateral tilt positioning if late pregnancy
Geriatric
Geriatric considerations
Higher fracture likelihood with low-energy trauma
Higher admission threshold for pain control and function
Opioid delirium risk mitigation
Bone health pathway
Fragility fracture screening
Osteoporosis follow-up planning
Pediatrics
Pediatric and adolescent considerations
Medial clavicle physeal injury as common mimic
Lower threshold for CT to define anatomy when posterior injury suspected
Weight-based analgesia and sedation dosing
Nonaccidental trauma context
Injury pattern inconsistent with history triggers safeguarding pathway
Background
Epidemiology
SC dislocation frequency
Rare compared with AC and glenohumeral dislocation
Posterior dislocation minority but highest risk
Typical populations
Contact sports participants
High-energy trauma patients
Adolescents with physeal vulnerability
Pathophysiology
Anterior dislocation mechanics
Anterior capsular and ligament disruption
Medial clavicle displaced anteriorly
Posterior dislocation mechanics
Posterior capsular disruption
Medial clavicle displaced into mediastinal space
Potential compression of trachea, esophagus, great vessels, brachial plexus
Therapeutic Considerations
Treatment rationale
Posterior displacement treated as time-critical due to mediastinal compression risk
Closed reduction success decreases with delayed presentation
Nonoperative pathway rationale
Anterior dislocation often stable with symptomatic care
Persistent prominence acceptable if function preserved
Operative pathway rationale
Posterior instability or recurrent instability may require reconstruction
Hardware choices avoid transfixing pins due to migration risk
Patient Discharge Instructions
Copy discharge instructions
Discharge packet
Sling use as directed
