Objectives To systematically review the efficacy of conservative treatment and open reduction with internal fixation for multiple rib fractures. Methods We searched WanFang Data, CNKI, VIP, PubMed, EMbase, The Cochrane Library and Web of Science from inception to December 2017 to collect studies on conservative treatment and open reduction with internal fixation for multiple rib fractures. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. RevMan 5.3 software was used for meta-analysis. Results A total of 16 studies were included, involving 1 374 patients, 723 patients in the surgical group and 651 patients in the conservative group. The meta-analysis showed that the length of stay in the ICU (MD=–3.41, 95%CI –4.92 to –2.43, P<0.000 01), total length of stay (MD=–7.60, 95 %CI–10.67 to–4.53,P<0.000 01), incidence of pulmonary arylene (RR=0.40, 95%CI 0.29 to 0.54,P<0.000 01), incidence of lung infections (RR=0.43, 95%CI 0.30 to 0.61,P<0.000 01), and incidence of chest wall malformation (RR=0.05, 95%CI 0.03 to 0.11,P<0. 0.000 01) in the surgical group were superior to the conservative group. Conclusions Compared with conservative treatment, open reduction with internal fixation can significantly improve the recovery time of patients with multiple rib fractures, reduce hospitalization time, the incidence of perioperative complications, and significantly enhance the prognosis of patients, which is more conducive to the rehabilitation of patients.
