Ilioinguinal approach versus Stoppa approach for open reduction and internal fixation in the treatment of displaced acetabular fractures: A systematic review and meta-analysis

Purpose: To compare the efficacy and safety of open reduction and internal fixation through ilioinguinal approach and Stoppa approach for the treatment of displaced acetabular fractures. Methods: Case-controlled trials (CCTs) published from January 2010 to August 2015 that compared the ilioinguinal approach and Stoppa approach in the management of displaced acetabular fractures were retrieved from the databases of Cochrane Library, Pubmed, CNKI, and so on. Methodological quality of the trials was critically assessed. Statistical software RevMan 5.0 was used for data analysis. Results: Eight articles were included in the meta-analysis. Through comparing the efficacy and safety of ilioinguinal approach and Stoppa approach in the treatment of displaced acetabular fracture, statistical significance was found in the average operation time WMD = 68.29, 95% CI (10.52, 126.05), p < 0.05] and the median intraoperative blood loss WMD = 142.26, 95% CI (9.30, 275.23), p < 0.05]. However, there existed no statistical significance in the fracture end reset satisfaction rate RR = 0.63, 95% CI (0.17, 2.37), p > 0.05], the early complications rate RR = 0.89, 95% CI (0.33, 2.40), p > 0.05], the late complications rate RR = 0.91, 95% CI (0.27, 3.01), p > 0.05], and Harris hip score good function rate RR = 0.52, 95% CI (0.25, 1.10), p > 0.05]. Conclusion: Though both techniques can obtain satisfactory clinical functions in the treatment of displaced acetabular fractures, Stoppa approach is superior to the ilioinguinal approach in terms of operation time and intraoperative blood loss.
