Tap Instrument For Dynamic Hip Screws

Description

Tap Instrument For Dynamic Hip Screws

The DHS tap cuts a thread for the lag screw in dense femoral head bone. It slides over the guide wire after reaming.

When to tap

In soft bone, the lag screw often cuts its own path. However, dense bone can resist and even rotate the head. Therefore the surgeon taps first in younger or denser bone.

Cannulated design

The tap has a central channel for the guide wire. As a result, it follows the reamed track exactly. Moreover, that keeps the thread aligned with the planned screw.

Who uses the DHS tap

Trauma surgeons use it in hip fracture fixation. Besides, it is part of the full DHS set. Teams keep it ready even if not every case needs it.

Tapping with the DHS tap

Advance the tap with steady turns of the handle. Then stop at the planned depth. Withdraw it carefully along the guide wire.

Checking the guide wire

The tap can push the guide wire forward. Consequently, watch the wire on imaging while tapping. Stop if it moves.
