Stabilization clamp for insertion of deep brain stimulation electrodes: technical note.
BACKGROUND
Deep brain stimulation (DBS) electrodes are being implanted with increasing frequency for the management of movement disorders and chronic pain. Success with this neuro-augmentative technique requires accurate electrode lead placement. In order to enhance accuracy of final lead placement and ease of insertion, we describe a useful and reliable DBS electrode lead stabilization device developed and used at our centre.


METHODS
The DBS electrode stabilization device consists of a 2-clamp system designed to fit the Leksell stereotactic frame. The clamps work in series to secure the stereotactic lead at the time of its final positioning in the desired subcortical target without the need of fluoroscopic control.


RESULTS
The DBS electrode stabilization device has been used in 30 patients for 54 electrode implantations at our institution since 2000. Postoperative magnetic resonance imaging was performed in all cases and confirmed accurate placement of the electrodes.


CONCLUSIONS
Accurate electrode lead placement is critical for the clinical efficacy of DBS systems. The simple and reliable stabilization device described here is easy to operate and enhances the final placement accuracy of DBS electrode leads.
