Trauma Surgery
Rib Fracture
Manage rib fracture as a thoracic-trauma risk problem: identify pneumothorax, hemothorax, pulmonary contusion, flail physiology, and respiratory compromise; use imaging selectively; and escalate analgesia or stabilization when pain or chest-wall instability impairs ventilation.
Immediate Priorities
Triage thoracic injury before counting fractures
The first decision is whether the rib injury is a marker of a dangerous chest-wall or intrathoracic injury.
In blunt thoracic trauma, actively evaluate for pneumothorax, hemopneumothorax, pulmonary contusion, flail chest, and nonthoracic injury rather than focusing solely on the number of fractured ribs. Rib fracture burden correlates with morbidity and mortality, and severe pain can impair ventilation and contribute to atelectasis, nosocomial pneumonia, and respiratory complications.

Escalate the level of observation when advanced age, multiple fractures, fracture location, or clinically important comorbidity increases the likelihood of hospital or ICU-level care. Hypoxia, failure to ventilate effectively because of pain, chest-wall instability, or inability to liberate from ventilatory support should prompt early trauma and chest-wall stabilization assessment.

Treat nontraumatic mechanisms as diagnostic branches. Fractures after aggressive CPR, severe cough, athletic activity, or without an adequate trauma mechanism warrant consideration of a pathologic process such as primary bone tumor or metastatic disease, rather than attribution to routine blunt trauma alone. In young children, rib fractures require an abuse evaluation because nonaccidental trauma accounts for 65% to 100% of cases.

Diagnostic Workup
Choose imaging based on associated injury risk, not fracture confirmation alone
Imaging should establish clinically consequential thoracic injury and guide disposition or intervention.
Use chest radiography as first-line imaging for known or possible thoracic trauma. Its immediate role is not merely to identify a rib fracture but to evaluate for complications such as pneumothorax, hemopneumothorax, and pulmonary contusion. BMJBMJRib fractures - Symptoms, diagnosis and treatment | BMJ Best Practice US
Use chest CT when the clinical question requires more complete fracture characterization or assessment of lung, mediastinal, or abdominal injury. CT is the preferred diagnostic imaging test for rib fractures and can evaluate associated injuries in the same examination.

Interpret a negative radiograph cautiously when clinical suspicion remains high. In a cohort of 8,661 patients who received both chest radiography and CT, 2,071 had rib fractures and 1,368 of those fractures were observed on CT only; a separate report found that 66% of fractures were seen only on CT.

Bedside or radiology-performed chest ultrasonography can improve fracture detection when CT is not otherwise indicated. Compared with CT, pooled ultrasound sensitivity was 89.3% and specificity 98.4%; cortical irregularity had a positive likelihood ratio of 55.7, while no ultrasonographic fracture had a negative likelihood ratio of 0.11. Ultrasound does not replace CT when the management question is associated intrathoracic or multisystem injury.

Ventilatory Protection
Treat pain that compromises ventilation with an escalation pathway
The clinically important analgesic endpoint is restored breathing and cough, not pain-score reduction alone.
Severe rib-fracture pain can impair ventilatory function and is associated with increased atelectasis, nosocomial pneumonia, and respiratory complications. Reassess whether the patient can breathe deeply, cough, and mobilize after analgesic intervention; persistent functional limitation should drive escalation.

Use ultrasound-guided serratus anterior plane block as a regional analgesic option for acute rib-fracture pain when systemic analgesia does not restore respiratory function or opioid exposure is undesirable. SAPB improves pain control in patients with rib fractures, and the technique has been evaluated specifically for early rib-fracture pain management.

Select regional technique according to fracture distribution, clinical setting, and procedural expertise. Thoracic paravertebral catheter techniques have been reported for rib-fracture analgesia, while continuous regional anesthesia may reduce opioid requirements in mechanically ventilated patients; these approaches require a setting capable of procedural placement and ongoing catheter management.

Do not use analgesic success to defer evaluation of associated trauma.

Definitive Management
Select surgical stabilization for instability or refractory respiratory consequences
Most rib fractures heal without surgery, but chest-wall instability and respiratory failure identify the key operative branch.
Most rib fractures heal without operative repair. Consider surgical stabilization of rib fractures when multiple fractures produce an unstable chest wall consistent with flail chest, or when injury severity causes ongoing hypoxia or prevents removal of mechanical ventilatory support. BMJBMJRib fractures – Patient education series: understanding trauma and emergency surgery conditions | Trauma Surgery & Acute Care Open
For multiple displaced rib fractures selected for fixation, aim for early operative assessment because fixation is ideally performed within 48 to 72 hours of injury. The timing decision should be coordinated with treatment priorities for associated thoracic and extrathoracic injuries. Wiley+1WileyManagement of major thoracic trauma: a narrative reviewBMJRib fractures - Symptoms, diagnosis and treatment | BMJ Best Practice US
Current fixation constructs commonly stabilize fractures with metal plates and screws. Titanium clips, bars, screws, and plates have been reported as effective and safe for repair of rib fractures and larger chest-wall defects, but operative selection remains driven by instability and respiratory consequence rather than the imaging finding of a fracture alone.

Escalate early to trauma, thoracic, or chest-wall surgery when CT demonstrates multiple displaced fractures with a clinically unstable chest wall, or when adequate analgesia does not reverse hypoxia or ventilator dependence. Delay can move fixation beyond the described 48- to 72-hour preferred window for displaced fractures. Wiley+1WileyManagement of major thoracic trauma: a narrative reviewBMJRib fractures – Patient education series: understanding trauma and emergency surgery conditions | Trauma Surgery & Acute Care Open
Flail chest is a principal indication for operative stabilization. BMJBMJRib fractures – Patient education series: understanding trauma and emergency surgery conditions | Trauma Surgery & Acute Care Open
Persistent hypoxia or failure to wean from mechanical ventilation can justify fixation assessment even when the immediate issue is respiratory rather than mechanical pain.

Reassessment
Monitor for pulmonary deterioration and identify patients needing higher-acuity care
Disposition should reflect respiratory trajectory and associated injury burden, not the presence of a fracture alone.
Reassess oxygenation, respiratory effort, cough effectiveness, and analgesia-responsive ventilatory function after initial treatment. Rib-fracture complications include pneumonia, respiratory failure, and pneumothorax; one report estimates that approximately 13% of patients experience one or more complications. WileyWileyRare Case of Acute Pulmonary Thromboembolism After ...
Use inpatient or ICU monitoring selectively for patients with advanced age, multiple fractures, clinically important fracture location, or comorbid disease that increases risk of deterioration. These factors increase the likelihood that hospital or ICU admission will be required. BMJBMJRib fractures – Patient education series: understanding trauma and emergency surgery conditions | Trauma Surgery & Acute Care Open
A changing respiratory examination or oxygen requirement should trigger renewed assessment for delayed or evolving thoracic complications, including pneumothorax, hemopneumothorax, and pulmonary contusion. Repeat imaging modality should match the unresolved clinical question, with radiography as the initial trauma study and CT when more complete injury assessment is needed.
