Smith & Nephew plc. is ending 2017 by closing its acquisition of Rotation Medical Inc. for $125 million in cash, plus an additional $85 million in potential milestone payments. The London-based company first revealed it would pick up the bioinductive implant-maker back in October in a deal that would be neutral for earnings in 2018 and boost them in 2019.
