Abstract
A rod reducer including a housing, a plurality of arm members, an anvil, a shaft, a sleeve, and a plurality of locking feet. The shaft and locking feet are coupled to the anvil. The housing is slidably disposed within a cavity of the sleeve and defines an opening to receive the shaft. The locking feet are additionally coupled to the sleeve and are pivotable between an engaged configuration with the sleeve in a distal position with respect to the anvil and a released configuration with the sleeve in a proximal position. In the engaged configuration an engagement surface of the locking feet couple to an outer housing of a dual layered housing of a bone screw such that proximal translation of the shaft drives the outer housing proximally with respect to an inner housing of the bone screw into a partially locked or locked configuration.
