Management of Nondisplaced Rib Fractures

Classification and Management

The Chest Wall Injury Society (CWIS) classifies nondisplaced rib fractures with >90% cross-sectional overlap, which applies to this patient's right posterior 10th rib fracture 1, 3
The fracture's location in the posterior region affects management considerations 4
The 10th rib's location in the lower thoracic region typically has less impact on respiratory mechanics than fractures of ribs 3-6 5
The American College of Surgeons recommends conservative management with adequate pain control and respiratory support for nondisplaced rib fractures, as surgical intervention is not indicated for isolated nondisplaced fractures 1, 2

Implement multimodal analgesia to control pain and allow for adequate respiratory effort, as recommended by the World Journal of Emergency Surgery 3, 6
Encourage deep breathing exercises and incentive spirometry to prevent atelectasis and pneumonia, as suggested by the World Journal of Emergency Surgery 3, 6
Early mobilization is recommended to prevent pulmonary complications 6
Clinical reassessment within 1-2 weeks is necessary to monitor for worsening displacement, development of complications, and adequate pain control 5

Surgical stabilization of rib fractures (SSRF) would be considered for multiple fractures (≥3 displaced rib fractures) 1, 2
SSRF would also be considered for flail chest segment 3, 7, severely displaced fractures (no cross-sectional overlap or overlapping ribs) 1, 2, or fractures with persistent respiratory impairment despite adequate pain control 2, 6

Monitor for signs of respiratory compromise (increased respiratory rate, decreased oxygen saturation) 6
Be alert for development of pneumothorax or hemothorax, although this is not present in the initial imaging 6

The 10th rib is not typically considered for surgical fixation unless there is marked displacement or organ impingement, as noted by the World Journal of Emergency Surgery 5

Inadequate pain control leading to splinting, poor respiratory effort, and atelectasis, as warned by the World Journal of Emergency Surgery 6
