How should I treat a 50-year-old female patient with a displaced left-sided rib fracture, who presented with left side rib pain after a fall, and has normal lung fields and overlying soft tissues?

Treatment of Displaced Left-Sided Rib Fracture

This patient requires aggressive multimodal analgesia and respiratory support with conservative management, as surgical stabilization is NOT indicated for a single displaced rib fracture without flail chest, respiratory failure, or severe refractory pain. 1, 2

Immediate Pain Management Protocol

First-Line Analgesia

• Start acetaminophen 1000mg every 6 hours on a scheduled basis (not as-needed), as this provides superior pain control when given regularly 1, 2
• Oral formulation is equally effective as IV and more practical for outpatient management 2

Second-Line Analgesia for Breakthrough Pain

• Add NSAIDs (such as ketorolac or ibuprofen) if acetaminophen alone is insufficient 1, 2
• Contraindications to avoid: aspirin/NSAID-induced asthma, pregnancy, cerebrovascular hemorrhage, active GI bleeding, or severe renal impairment 1, 2

Opioid Use (Reserve as Last Resort)

• Use only for severe breakthrough pain at the lowest effective dose and shortest duration 1
• Particularly avoid in this 50-year-old patient if possible, as respiratory depression risk increases with age 1

Non-Pharmacological Adjuncts

• Apply ice packs or cold compresses to the painful area alongside medications 2
• These simple measures enhance overall pain control 2

Respiratory Care Protocol (Critical to Prevent Complications)

Mandatory Interventions

• Incentive spirometry performed while sitting: take slow deep breaths, hold 3-5 seconds, then exhale 1
• Continue this for at least 2-4 weeks to prevent atelectasis and pneumonia 1
• Perform deep breathing exercises and gentle coughing regularly to clear secretions 1
• Early mobilization is mandatory - the patient should not remain sedentary 1, 3

Why This Matters

• Under-treatment of pain leads to splinting, shallow breathing, poor cough, atelectasis, and pneumonia - this is the most common pitfall 1, 3
• Rib fractures are associated with pulmonary complications including atelectasis, impaired secretion clearance, and pneumonia 4

Risk Stratification for This Patient

This 50-year-old patient has lower risk for complications based on available information, but assess for these high-risk factors 1, 2:

• Age >60 years (she is 50, so lower risk)
• SpO2 <90% (check oxygen saturation)
• Obesity or malnutrition
• Smoking or chronic respiratory disease
• Anticoagulation therapy
• Presence of ≥5 consecutive rib fractures (she has one displaced fracture)

If any high-risk factors are present, consider more aggressive pain management including regional anesthesia 1, 2

Why Surgery is NOT Indicated

Surgical stabilization of rib fractures (SSRF) is reserved for specific indications that do NOT apply to this patient 1, 2:

• Flail chest (≥2 consecutive ribs each fractured in ≥2 places) - not present
• ≥3 ipsilateral displaced fractures - she has only one
• Respiratory failure requiring mechanical ventilation - not present
• Severe refractory pain despite optimal multimodal analgesia - not yet attempted

The single displaced rib fracture, despite the displacement noted on imaging, does not meet surgical criteria 1, 2, 3

Follow-Up and Monitoring

Schedule Clinical Reassessment Within 1-2 Weeks

• Monitor for worsening displacement 1, 3
• Assess adequacy of pain control 1
• Evaluate for development of complications 1

Red Flags Requiring Immediate Attention

Instruct the patient to return immediately if she develops 1, 2:

• Worsening dyspnea or respiratory distress
• Fever >38°C (100.4°F)
• Productive cough with yellow, green, or bloody sputum
• Progressive oxygen desaturation
• Chest pain that suddenly worsens
• Dizziness, fainting, or confusion

Expected Recovery Timeline

• Pain improvement: Should see significant improvement by 4 weeks with appropriate management 1, 2
• Bone healing: Typically 6-8 weeks 1, 2
• Functional recovery: Return to normal activities takes 8-12 weeks 1, 2
• Complete pain resolution: May take up to 2 years in some patients 1, 2

Critical Pitfalls to Avoid

1. Under-treating pain - This leads to immobilization, shallow breathing, and preventable pneumonia 1
2. Over-relying on opioids - Causes respiratory depression, especially problematic in older patients 1
3. Failing to implement respiratory physiotherapy - Results in preventable pulmonary complications 1
4. Ignoring the discrepancy between the radiology report (which states "No displaced rib fracture" in findings but "Evidence of displaced left-sided rib fracture" in impression) - Clarify this with the radiologist, as management depends on actual displacement 4

Note on Imaging Discrepancy

The X-ray report contains a contradiction: the findings state "No displaced rib fracture" but the impression states "Evidence of displaced left-sided rib fracture." This needs clarification, as chest X-rays miss up to 50% of rib fractures 4, 2. However, treatment remains the same whether the fracture is displaced or nondisplaced, focusing on pain control and respiratory support 4, 1
