Abstract
An instrument for breaking off and retaining the tab of a reduction screw is provided. The instrument includes a breaking arm and a retaining mechanism. The breaking arm is configured to break off an excess portion of the tab of the reduction screw about a weakened section. The retaining mechanism is configured to retain the broken off tab and preventing the tab from falling into a surgical site. The retaining mechanism is further configured to allow the instrument to engage another tab while simultaneously holding a predetermined number of previously broken off tabs. Accordingly, the instrument reduces surgical time as the surgeon may simply move from one reduction screw to another while breaking off the tabs until the instrument can no longer retain additional broken off tabs.
