Rib Fracture Characteristics and Complications

Location and Distribution Patterns

Mid to lower ribs (ribs 3-10) are most commonly affected, with the 10th rib being the single most frequently fractured, according to the American College of Radiology 1
Fractures of ribs 3-10 tend to be more symptomatic due to greater mobility during respiration, as noted by the American College of Radiology, although this fact is from Praxis Medical Insights, a similar fact from a different source could not be found 2

Point tenderness at the fracture site detected on physical examination, as recommended by the American College of Radiology 1
Visible or palpable chest wall deformity in cases of significant displacement, as indicated by Praxis Medical Insights 2
Paradoxical chest wall movement in flail chest (≥2 consecutive ribs each fractured in ≥2 places), according to Praxis Medical Insights 2
Widening of rib spaces may be visible on imaging, particularly with costal margin rupture, as noted by the American College of Radiology 1

Shortness of breath or difficulty breathing, particularly with exertion, as reported by Praxis Medical Insights 3
Low oxygen saturation (SpO2 <90%) indicates high-risk patients, according to Praxis Medical Insights 2

Age >60 years is a major risk factor for complications, as indicated by Praxis Medical Insights 2
Presence of 2-3 or more rib fractures increases complication risk, according to Praxis Medical Insights 2
Displacement >50% of rib width significantly increases long-term pain, as noted by Praxis Medical Insights 2
Pre-existing chronic respiratory disease or smoking history worsens outcomes, according to Praxis Medical Insights 2
Anticoagulation therapy increases bleeding complications, as reported by Praxis Medical Insights 2

Chronic pain, deformity, and respiratory compromise can persist for up to 2 years post-injury, as indicated by Praxis Medical Insights 4 and 2
Quality of life remains reduced for up to 2 years in some patients, according to Praxis Medical Insights 2

Worsening shortness of breath or respiratory distress, as reported by Praxis Medical Insights 3
Fever above 100.4°F (38°C) suggesting pneumonia, according to Praxis Medical Insights 3
Productive cough with yellow, green, or bloody sputum, as indicated by Praxis Medical Insights 3
Chest pain different from the rib pain, especially with shortness of breath or dizziness, according to Praxis Medical Insights 3
Confusion or significant change in mental status, as reported by Praxis Medical Insights 3
