Abstract
A medical instrument for measuring depth of fastener hole in bone. The depth gauge has a scale tube which fits into fastener hole in bone. The zero index of scale tube expands exclusively in radial dimension to a diameter greater than the hole diameter, affording a positive stop for the zero index, thus insuring precise alignment of scale zero index with edge of hole in distal bone wall. A sliding scale marker is frictionally mounted to scale tube, affording a record of the measurement.
