| 1. An instrument for measuring blind holes in bones or implants inserted within bones, comprising:
a. an elongated probe having a proximal end, a distal end, a longitudinal axis, and a scale on the proximal end of the probe;
b. a housing slidably mounted relative to the scale;
c. an abutment formed at the distal end of the probe, the abutment configured and dimensioned to fit through a hole to be
measured;
d. an elongated insert having a longitudinal groove with a transverse section corresponding to a transverse section of the
probe, the groove configured and dimensioned to permit sliding of the insert with respect to the probe along the longitudinal
axis;
wherein sliding of the insert toward the proximal end of the probe causes movement of the abutment toward a distal wall adjacent
the hole.
