Double Drill Guide

Description

Double Drill Guide

The double drill guide has a bore at each end for two different drill sizes. Surgeons use it for lag screw technique, where two hole sizes are needed.

Lag screw basics

A lag screw compresses two fragments together. To do that, the near fragment gets a larger gliding hole and the far fragment a smaller thread hole. Therefore two guides, or one double guide, are needed.

Two versions

Choose 3.2 / 6.5 mm or 4.5 / 3.2 mm. Furthermore, the 4.5 / 3.2 mm version suits 4.5 mm cortical lag screws. Meanwhile, the 3.2 / 6.5 mm version pairs a 3.2 mm drill with larger screw work.

Who uses a double drill guide

Trauma surgeons use it in fracture fixation with lag screws. It also helps in osteotomy fixation. Scrub staff keep it with the drill bits.

Drilling sequence

Drill the near cortex with the larger bit first. Then insert the guide’s small end and drill the far cortex. Afterward, measure and insert the screw.

Fewer instruments

One double guide replaces two single guides. Consequently, the tray stays tidier. Turning the guide around is quick.
