ABSTRACT:
Liquid material is directed under pressure into a hole, such as a hole formed in a bone. The vessel from which the liquid is directed, such as a syringe or squeeze bulb tube, provides a seal at the point of contact between the vessel and the hole to maintain a closed system. After the liquid is directed into the hole, a continued drop in liquid volume within the vessel is accompanied by a rapid drop in air pressure, which is measured by a gauge, indicating a deficit in the structural integrity of the hole.
