Tips and Tricks for Removing Problematic Implants: Plates
When all the screws have been removed, the plate can also be removed. As a general rule, this should not pose a problem provided that there is sufficient access.
Tips and tricks for removing minimally invasively inserted plates
- In the insertion area, use a chisel to release the plate.
- Try to extract the plate (see below); if this fails to achieve the desired result:
- Release the plate with the aid of a chiselexactly the same width as the plateeither above or below the plate.
- Use right-angled chisels in order to progress along the entire edge.
- All these chisels should be advanced with care or they should be propelled forward with light hammer blows.
- In our experience, a traditional Kntscher extraction hook with a long shank and a recess for a slot hammer has proved to be effective (Fig 9). Using light hammer blows, the plate can then be loosened and progressively extracted. Other types of hook can also be used.
- Check whether there is any bleeding from the position of the plate and from the entire canal of the former implant.
- Another way of releasing a plate is to rotate it about its longitudinal axis.
