title: Early intramedullary nailing of femoral shaft fracture on outcomes in patients with severe chest injury: A meta-analysis.
abstract: Early intramedullary nailing (IMN) within the first 24 hours for multiply injured patients with femoral fracture and concomitant severe chest injury is still controversial. This review aimed to investigate the association between early IMN and pulmonary complications in such patients. We searched the literature up to Jan 2016 in the main electronic databases (PubMed, Web of Science, Cochrane library databases) to identify eligible studies. Data were extracted and analyzed using a Mantel-Haenszel method with random-effects model to estimate pooled odds ratio (OR) and 95% confidence intervals (CIs). Seven retrospective cohort studies were identified eventually. The pooled estimates demonstrated that the application of early IMN did not significantly increase the risk of adult respiratory distress syndrome (ARDS) (OR, 0.65; 95% CI: 0.38-1.13), mortality (OR, 0.79; 95% CI: 0.43-1.47), pneumonia (OR, 0.92; 95% CI: 0.55-1.54), multiple organ failure (MOF) (OR, 0.87; 95% CI: 0.45-1.71) and pulmonary embolism (OR, 1.81; 95% CI: 0.28-11.83). In subgroup analysis according to the type of IMN (reamed or undreamed), we did not find any significant difference either. Our results indicated that early IMN of femoral shaft fracture was not associated with increased rates of pulmonary complications in severe chest-injured patients.
