Event or Problem Description
As reported by the rep: "surgeon requested for a 44/2 exeter stem to be opened, the outside box and inside stickers were checked by surgeon and scrub staff, both were correct.However, after cementing the surgeon decided to check the laser marking on the stem as something seemed amiss, the code on the stem was actually: 0580-1-352 which corresponds to a 37.5/0 exeter stem.No other stems were opened during that case and stickers and box were checked again showing: 0580-1-442, a 44/2 150mm exeter stem.Surgeon used a plus head instead of a minus head, with the smaller stem to account for the difference.".
