Indications for Rib Plating (SSRF)
Rib plating should be performed for flail chest, multiple displaced rib fractures (≥3 ribs with ≥50% displacement), and patients with persistent respiratory impairment or severe pain despite optimal medical management. 1
Primary Indications
1. Flail Chest
- Definitive indication: ≥2 consecutive ribs each fractured in ≥2 places creating paradoxical chest wall movement
- Associated with reduced mortality, shorter mechanical ventilation, decreased pneumonia rates, and shorter ICU stays when surgically stabilized 1
2. Multiple Displaced Rib Fractures (Non-Flail)
Critical threshold: ≥3 ipsilateral displaced fractures of ribs 3-10 with displacement ≥50% of rib width on axial CT 1
Must have at least 2 of the following pulmonary derangements after initiation of regional anesthesia:
- Respiratory rate >20 breaths/minute
- Incentive spirometry <50% predicted
- Pain score >5/10
- Poor cough effectiveness
This represents the most recent high-quality evidence showing SSRF reduces pleural complications, pain, and respiratory disability 1
3. Unstable Chest Wall Injuries
Consider SSRF for:
- ≥3 fractures with severe displacement (>100% overlap) or overriding (≥15mm each)
- Rib protrusion into lung parenchyma
- ≥25% hemithorax volume loss
- Associated with decreased mortality (0% vs 6%) in ventilated patients 1
4. Persistent Severe Pain
- Patients with severe pain despite multimodal analgesia and regional blocks
- Pain as sole indication remains debated but shows reduced narcotic requirements post-operatively 2
Special Populations Where SSRF Should Be Considered
Traumatic Brain Injury (TBI)
- Mild to moderate TBI (GCS 9-15): SSRF associated with lower pneumonia risk, reduced 30-day mortality, and shorter ICU stay 1
- Severe TBI (GCS ≤8): Recent evidence shows reduced mortality with SSRF; no longer an absolute contraindication 1
- Pneumonia is a strong independent predictor of mortality in polytrauma patients—SSRF helps prevent this 1
Elderly Patients
- Do not withhold based on age alone 1
- Elderly patients may benefit MORE than younger counterparts as they tolerate rib fractures poorly and deteriorate faster
- SSRF safe and reduces mortality compared to non-operative management, though hospitalization may be longer 1
Pulmonary Contusion
- Not a contraindication 1
- Mild-moderate contusion: SSRF reduces respiratory failure, tracheostomy, mechanical ventilation duration, and hospital stay
- Severe contusion: Recent evidence shows benefits regardless of severity 1
Timing Algorithm
Optimal window: 48-72 hours from injury 1
If contraindications exist initially (hemodynamic instability, ongoing resuscitation):
- Perform SSRF as soon as stable, ideally within 3-7 days
- Early SSRF minimizes pneumonia, reduces technical complexity (less inflammation, hematoma, callus formation)
Key Contraindications
Absolute
- Hemodynamic instability (though patients on low, stable vasopressors may benefit if SSRF facilitates weaning sedation) 1
- Age <18 years (FDA exclusion; plates may need removal within 3 months) 1
Relative (Assess individually)
- Active empyema (hardware infection risk)
- Prior chest wall radiation (hardware failure risk)
- High spinal cord injury/quadriplegia (may not benefit from pain control)
- Uncorrected coagulopathy
- Terminal illness 1
Common Pitfalls to Avoid
Waiting for "late failures": This introduces selection bias and misses the window for optimal benefit. Operate early (48-72h) when indicated 1
Excluding elderly patients: Age alone should not preclude surgery—elderly patients often benefit most 1
Assuming TBI is a contraindication: Even moderate-severe TBI patients benefit from SSRF with reduced mortality and pneumonia 1
Dismissing non-ventilated patients: Those with ≥3 displaced fractures and persistent respiratory impairment/pain benefit significantly from SSRF 1
Using pain as sole criterion without objective measures: Combine pain assessment with respiratory parameters (incentive spirometry, respiratory rate, cough effectiveness) 1
The evidence strongly supports expanding SSRF indications beyond traditional flail chest to include multiple displaced fractures with respiratory compromise, even in previously excluded populations like TBI and elderly patients 1.
