Depth gauge
A rod-shaped instrument with a hooked tip and a millimeter scale, inserted into a drilled hole in the bone.
How it is used
Used to measure the depth of a drilled bone hole and determine the correct length of screw to be inserted.
Clinical tip
Measurement accuracy improves with experience, so the reading is often double-checked before picking a long screw.
