When telephone lines go down, or Internet connections are lost, our communities temporarily come to a halt. What if something similar were found to be happening in Parkinson's? This is the focus of Dr. Schmitz and her team at the PDF Research Center at Columbia University Medical Center.

Background and Objectives: Individually manufactured microTargeting? platforms (MT) provide a novel generation of stereotactic systems based on preoperatively implanted bone markers and screws. The feasibility and reliability of these frames were evaluated for bilateral deep brain stimulation (DBS) in patients with idiopathic Parkinson's disease (IPD). Surgical and clinical results were compared to conventional Zamorano Dujovny frames (ZD) in this prospective study. Materials and Methods: Twenty-six IPD patients undergoing surgery for DBS were divided into 2 groups. In group I, electrode implantation was accomplished using conventional ZD. Group II underwent electrode implantation using MT. Microrecording and macrostimulation were performed and surgery time was measured. The clinical outcome was determined using the Unified Parkinson's Disease Rating Scale Part III (UPDRS III) and L-dopa-equivalent doses for a 12-month follow-up postoperatively. Results: Clinical evaluation confirmed comparable outcomes for both targeting procedures and electrode positioning. Surgical time was lower in group II than in group I. Significant improvements were determined for both groups in UPDRS III and L-dopa-equivalent dose. Conclusions: Both systems allow for reliable and safe neurosurgical procedures, yielding comparable clinical results. MT improved handling and automatic adjustment of frame coordinates. Surgery time was reduced markedly compared to conventional frames. © 2013 S. Karger AG, Basel.
