Intramedullary fixation versus plate fixation for displaced mid-shaft clavicle fractures: A systematic review of overlapping meta-analyses.

Displaced mid-shaft clavicle fractures (DMCFs) are common injuries. Both intramedullary fixation (IMF) and plate fixation (PF) have been described and routinely used. Multiple trials have been conducted to compare these treatments. Multiple meta-analyses have been published to compare IMF and PF treatment for DMCFs; however, the results remain controversial. The purposes of this study were to perform a systematic review of overlapping meta-analyses comparing IMF and PF treatment for DMCFs, to help decision makers critically evaluate the current meta-analyses, and to propose a guide through the best available evidence.
