Surgical stabilisation of rib fractures: A meta-analysis of randomised controlled trials

Abstract

IntroductionRib fixation for ventilator dependent flail chest patients has become a mainstay of management in major trauma centres. However, the expansion of rib fixation for fractured ribs beyond this remains largely in the hands of enthusiasts with the benefits in non ventilator dependent groups largely unproven. Previous meta-analyses have largely included non-randomised and retrospective data, much of which is now more than two decades out of date. We wanted to perform an updated meta-analysis including only rigorous prospective trials which were randomised. Further we wanted to include quality of life outcomes which have not been previously examined in published meta-analyses. MethodsThis meta-analysis was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and included randomised controlled trials only, of rib fixation compared to non-operative management in adult patients. ResultsEight studies comprising 752 patients of whom 372 had been randomised to receive rib fixation were included. Benefits of rib fixation were identified with significant reductions in mechanical ventilation and lengths of stay (both ICU and hospital) as well as rates of pneumonia and tracheostomy. No significant benefit in quality of life at 6 months was identified. ConclusionOperative intervention for rib fractures leads to significantly lower rates of pneumonia, lengths of intensive care stay and time on mechanical ventilation compared to non-operative intervention. Further study is needed to investigate quality of life improvements after rib fractures as operative rib fixation expands to non-ventilator dependent groups.
