Surgical Stabilisation of Rib Fractures

The problem being fixed

Multiple rib fractures cause pain that prevents deep breathing and effective coughing, leading to retained secretions, loss of lung volume and pneumonia. Where a segment of chest wall is separated from the rest — flail chest, classically three or more consecutive ribs fractured in two or more places — that segment moves paradoxically and ventilation becomes mechanically inefficient as well as painful.

Crucially, most of the respiratory failure after severe chest wall trauma is caused not by the ribs themselves but by the underlying pulmonary contusion and by pain. Surgical stabilisation addresses the mechanics; it does not treat the contusion. See Flail Chest.

What the operation involves

Fractured ribs are exposed, reduced and fixed with contoured titanium plates and screws, or occasionally intramedullary devices. Access is through muscle-sparing incisions over the fracture sites, sometimes with thoracoscopic assistance to inspect the pleural cavity, evacuate haemothorax and place a drain. Fixation is usually undertaken within the first few days, and earlier surgery is generally associated with better outcomes than delayed.

Who benefits — and what the evidence shows

The evidence is genuinely mixed, and it is worth being precise rather than enthusiastic.

• Flail chest. Marasco and colleagues randomised patients with ventilated traumatic flail chest to operative fixation or continued mechanical ventilation and found reduced ventilator hours and shorter intensive care stay in the surgical arm.¹ Cochrane review of surgical versus non-surgical management of flail chest concluded that fixation may reduce pneumonia, ventilation duration, intensive care stay and chest deformity, but on a small and methodologically limited evidence base.²
• Severe non-flail fracture patterns. The Chest Wall Injury Society multicentre controlled trial in severe non-flail patterns found no difference in the primary respiratory outcomes, though secondary measures including pain and narcotic requirement favoured surgery in some analyses.³ This tempered the enthusiasm for extending fixation to all multiple-fracture patients.
• Practice guidance. The Eastern Association for the Surgery of Trauma conditionally recommends fixation for adults with flail chest, while noting the limited quality of evidence.⁴

Risk stratification

Outcome after blunt chest wall trauma is driven by age, number of fractures, pre-existing lung disease, oxygenation and pre-injury anticoagulation, and validated prognostic models exist to identify patients needing higher-level care.⁶ An older patient with three fractures and chronic obstructive pulmonary disease may be at higher risk than a young patient with six.

Practical translation: do not stratify physiotherapy intensity by fracture count alone. Age, comorbidity, baseline function and the quality of analgesia matter more.

Physiotherapy after chest wall trauma and fixation

The plan is broadly the same whether or not the ribs were fixed, with the difference that a fixed chest wall is usually less painful on movement and permits earlier progression.

• Analgesia first, every session. Time treatment to peak analgesic effect and escalate rather than working around inadequate pain relief.
• Deep breathing and supported coughing, with a pillow or the patient's own hands over the site. Sputum retention is the commonest reason these patients deteriorate.
• Early mobilisation and upright positioning, which do more for lung volumes than any bed-based technique.
• Watch the underlying injury. Pulmonary contusion typically worsens over the first 24 to 72 hours; deterioration in that window is usually the contusion evolving rather than a failure of treatment.
• Shoulder and thoracic mobility on the operated side, which stiffens quickly with guarding.
• Incentive spirometry is commonly used in trauma protocols; the general surgical evidence is weak, and it should not displace mobilisation. See Incentive Spirometry.
• Non-invasive ventilation may be used for hypoxaemic failure. There is no absolute prohibition after fixation, but confirm with the surgical team where a pleural injury or air leak exists.
• Chest drains are frequently present — mobilise with them. See Chest Drains.

Longer term

Persistent chest wall pain, intercostal neuralgia, reduced trunk range and fear of movement are common at three to six months, and a proportion of patients develop chronic pain. Implant irritation or infection occasionally requires removal. Return to heavy work and contact sport is guided by the surgical team, typically once fracture union is established.

Role of the physiotherapist

Treat the pain and the contusion, not the metalwork. Push analgesia hard enough to make deep breathing and coughing possible, mobilise early, and expect the contusion to worsen before it improves. Recognise that fixation changes the mechanics and the comfort but not the underlying lung injury — and that the patient who has not been fixed needs the same care, delivered more carefully.
