"we noticed on the stem, after impacting tray, white blotchy.Didn't rub off.Decided to open a 3b stem after compacting new size.When 3b stem was opened we noticed plastic flecks on the stem.We wiped them off and impacted the tray on the new stem.After tray impaction we noticed these white marks again on both sides of the stem.We determined this was an issue with the impaction block mwf107.The 3b stem was implanted.No back up available.Had to open and compact for size up.Not the best size and fit.".
