References: Latch Reamers Warning

Warning:
The reamers are used sequentially beginning with a 2.5mm diameter and ending with the diameter of the intended implant. The newest reamers have horizontal markings at 6.0, 8.0, 11, 14 and 17mm, whereas older reamers may have different markings. It is imperative that the depth indicators on the latch reamers are identified prior to surgery. No assumptions should be made about the height of the first marking on any latch reamer.
