[Treatment of clavicular fractures using intramedullary nailing or K-wire versus plating fixation: a meta-analysis].

ABSTRACT

OBJECTIVE: TFo compare the efficacy and complications rate of intramedullary (IM) nailing or K-wire versus plating fixation for clavicular fractures. METHODS: Pubmed, Embase, Cochrane Library databases, CNKI, VIP and Wangfang databases were searched to find all randomized or quasi-randomized controlled trials of clavicle fractures using plating versus IM nailing or K-wire. The methodologic quality of the studies was assessed. After independent study selection by 2 authors ,data were collected and extracted independently. Outcomes of postoperative shoulder functional measurement, the efficacy and information of the operation and complications rate were meta-analyzed using RevMan 5 software. RESULTS: Nine hundreds and seventy-six patients in 10 randomized controlled trials (RCTs) and 3 quasi-RCTs were involved in the meta-analysis,of which 5 studies compared the K-wire and the plating fixations and 8 studies compared the IM nailing and the plating fixations. The overall odds ratio(OR) (with 95% CI) of the operation efficacy for K-wire versus the plating was 3.79 (1.93, 7.46). The overall weighted mean difference (with 95% CI) of Constant Shoulder score for plating versus IM fixation was -1.39 (-3.43, 0.65) in 6 studies. The overall OR of the plating versus IM nailing was 9.34(2.70, 32.32) for the overall major complications in 5 studies and 5.04 (1.52,16.77) for the revision rate in 5 studies. CONCLUSION: The current limited evidences suggested that the IM fixation could reduce the incidences of the overall major complications and the revision surgery, while the post-operative efficacy of the plating was superior to the K-wire. More high quality RCTs are still needed in the future.
