Round depth gauge

A system for measuring a depth of a blind hole formed through a bone, comprising:

• a first elongated rod including a shaft extending from a proximal end to a distal end, the distal end including an increased diameter abutment extending radially outward therefrom, the abutment including a proximal surface formed to contact a portion of the bone adjacent a distal opening of the blind hole to assume a locked configuration with the bone;
• a second elongated rod extending from a proximal end to a distal end along a longitudinal axis, the second rod including an increased diameter insert, the insert having a groove extending therethrough, the groove being sized and shaped to slidably receive the first rod therethrough;
• and
• a cylindrical housing have a substantially cylindrical channel extending therethrough to slidably receive the first and second elongated rods.

A method for measuring a depth of a blind hole formed through a bone, comprising:

• inserting a first elongated rod into a proximal opening leading into the blind hole and out of a distal opening of the blind hole such that an increased diameter abutment located at a distal end of the first rod is positioned distally of the distal opening;
• slidably moving a second elongated rod relative to the first rod such that a distal end thereof is positioned adjacent the abutment, a combined diameter of the abutment and the distal end of the second rod being greater than a diameter of the distal opening;
• retracting the first rod proximally until the abutment is seated against the distal opening;
• and
• advancing a housing encasing a proximal length of the first and second rods therein distally until a distal end of the housing contact the proximal opening so that the housing aligns with a marking corresponding to a depth of the blind hole.
