Abstract
Various methods and devices for measuring the dimensions of a bone hole or cavity are provided. In one exemplary embodiment, a device for measuring the depth of a bone hole includes a depth indicator that is adapted to measure a depth of a bone hole, and a positioning member disposed through the depth indicator for positioning the device relative to the bone hole.
Claims24
A surgical measuring device, comprising:
- an indicator adapted to measure a dimension of a bone hole;
- and
- a positioning member disposed through the indicator and having a distal end that, upon retraction of a portion of the positioning member, is adapted to radially expand to engage bone to position the positioning member relative to a bone hole, thereby allowing the dimension of the bone hole to be measured using the indicator.
A method for measuring the depth of a bone hole, comprising:
- inserting a depth gauge device through a bone hole;
- retracting at least a portion of the device to radially expand a distal end of the device and to cause the radially expanded distal end to engage bone;
- and
- distally advancing a depth indicator into the bone hole to measure the depth of the bone hole.

A method for measuring the diameter of a cavity, comprising:
- inserting a gauge device into a cavity;
- retracting at least a portion of the device to radially expand a distal end of the device and to cause the radially expanded distal end to engage an inner surface of the cavity;
- and
- calibrating the device such that the amount of retraction corresponds to the diameter of the cavity.
