These versatile depth gauges are ideally suited for a variety of screws and provides the surgeon with an accurate measurement for the appropriate selection of screw length. Like most other manufacturers, the length of VOI screws includes the head of the screw. This needs to be taken into account when measuring the depth of a hole. It???s also important to add 2-3mm to the depth measurement to account for full engagement of the trans-cortex by self-tapping screws. Some depth gauges already take the screw head into account. To check this, read the gauge when it???s fully retracted. If it reads zero, then you need to add approximately 3-5mm onto any measurement. If it reads ~2mm then it has taken the screw head into account and only 2-3mm needs to be added to the depth measurement.
