The purpose of this study was to compare the complication risk of different treatments for displaced intra-articular calcaneal fractures (DIACFs). Randomized controlled trials comparing interventions for DIACFs were included: (1) interventions with conservative treatment, surgery with a minimally invasive approach (MIA) (sinus tarsi or small longitudinal), surgery with a percutaneous approach (PA) and open surgery with the extensive "L" lateral approach (ELA), and (2) complications and wound infections were also assessed. Twenty-six published trials met the inclusion criteria. The trials involved a total of 2538 patients surgically treated for acute DIACFs. For total complications, the mean incidence rate in the ELA was significantly higher than the rates in other treatments (conservative treatment vs ELA: odds ratio (OR), 0.36; p < .001; MIA vs ELA: OR, 0.23; p = .002; and PA vs ELA: OR, 0.18; p < .001). For wound infections, there were no significant differences among the groups (MIA vs PA: OR, 0.98; 95% CI, 0.32-3.01; p = .977; MIA vs ELA: OR, 0.45; 95% CI, 0.19-1.10; p = .081; and PA vs ELA: OR, 0.46; 95% CI, 0.19-1.11; p = .085). According to the surface under the cumulative ranking curve, the PA was most likely to be the best management for minimizing complications (surface under the cumulative ranking curve = 86.2). The ELA was significantly related to a higher risk of complications among all management methods. The PA was most likely to be the ideal choice when only complications were considered.
