Inclusion criteria were patients between the ages of 16 to 85 years with displaced rib fractures with a flail chest or non\u2013flail chest injuries with severe chest wall deformity. Exclusion criteria included patients with significant other injuries that would otherwise require prolonged mechanical ventilation, those medically unfit for surgery, or those who were randomly assigned to study groups after 72 hours of injury.
