Background:

Deep brain stimulation (DBS) is a common treatment for movement disorders and pain.
Electrode stability is crucial for effective and safe DBS therapy.
Current methods for electrode fixation may have limitations.

Purpose of the Study:

To introduce and evaluate a new technique for anchoring DBS electrodes using a titanium microplate.
To assess the safety and efficacy of this microplate anchoring system.

Main Methods:

A titanium microplate was utilized to secure quadripolar DBS electrodes.
The technique was applied to 20 patients undergoing DBS implantation for movement disorders (18) and pain (2).
Electrode placement included the thalamus (12), subthalamic nucleus (4), and pallidum (4).

Main Results:

The titanium microplate technique was safely applied to 20 DBS electrodes.
No instances of electrode migration or rupture were observed.
All implanted electrodes demonstrated proper functionality after system internalization.

Conclusions:

The titanium microplate offers a safe and effective method for anchoring DBS electrodes.
This technique ensures electrode stability and maintains therapeutic efficacy.
The findings support the use of titanium microplates in DBS surgery.
