Abstract
A drill guide system comprising: a hemispherical cup having an opening therein; a body having a distal end, a proximal end and a lumen extending between the distal end and the proximal end; and a connector for connecting the body to the hemispherical cup so that the lumen at the distal end of the body is aligned with the opening in the hemispherical cup.

A drill guide system comprising;
- a hemispherical cup having an opening therein;
- a body having a distal end, a proximal end and a lumen extending between the distal end and the proximal end;
- and
- a connector for connecting the body to the hemispherical cup so that the lumen at the distal end of the body is aligned with the opening in the hemispherical cup.

A drill guide system comprising:
- a surgical implant comprising a hole and a mount adjacent the hole;
- a drill guide comprising an elbowed hollow tube having a distal end, a proximal end and a lumen extending between the distal end and the proximal end;
- and
- a flexible drill comprising a distal end, a proximal end and a flexible shaft extending from the distal end to the proximal end;
- wherein the distal end of the drill guide comprises a complementary mount for mating with the mount of the surgical implant so that the lumen at the distal end of the tube is aligned with the opening in the surgical implant.

A depth gauge comprising:
- a shaft having a distal, end and a proximal end, the distal end of the shaft being split so as to form at least two dilatable arms, at least one of the arms having a laterally-extending flange having a surface facing in the proximal direction, such that when the depth gauge is passed all the way through a hole in a bone, the flange can engage the far surface of the bone.
A method for forming a hole in a bone adjacent to an acetabular cup of the sort having a hole therein, the method comprising:
- providing a drill guide system comprising:
- a hemispherical cup having an opening therein;
- a body having a distal end, a proximal, end and a lumen extending between, the distal end and the proximal end;
- and
- a connector for connecting the body to the hemispherical cup so that the lumen at the distal end of the body is aligned with the opening in the hemispherical cup;
- positioning the acetabular cup in the bone;
- positioning the drill guide against the interior surface of the acetabular cup so that the opening in the hemispherical cap is aligned with the hole in the acetabular cup;
- passing a drill through the lumen, through the opening in the hemispherical cup, through the hole in the acetabular cup, and into the bone.
