Comparison of Robotic Arm and Stereotactic Frame Techniques in DBS Surgery
Overview
This retrospective study compared the Neuromate stereotactic robot with the Leksell G stereotactic frame in deep brain stimulation (DBS) surgeries for Parkinson’s disease. The robotic system demonstrated comparable radiological accuracy and clinical efficacy but was associated with longer surgical times.
Background
Deep brain stimulation is a well-established surgical treatment for movement disorders such as Parkinson’s disease, essential tremor, and dystonia. Traditionally, the stereotactic frame has been the gold standard for precise electrode implantation. Robotic-assisted surgery has recently emerged as a promising alternative, offering enhanced precision and potentially faster recovery. However, no prior studies have comprehensively compared the effectiveness, safety, and radiological accuracy of stereotactic robots versus frames in DBS.

Key Findings
The Neuromate robotic arm and the Leksell G stereotactic frame showed no significant differences in primary confounding clinical variables.
Surgical time was significantly longer in the robotic arm group (3.8 ± 0.9 hours) compared to the frame group (3.2 ± 0.6 hours; P = 0.004).
Radiological accuracy was assessed by radial and vector errors, though specific comparative data were not provided in the excerpt.
Both groups underwent similar preoperative planning and surgical execution aside from the electrode implantation method.
Additional intraoperative radiological studies (O-Arm) were used in nearly 80% of robotic cases as a precaution but later deemed unnecessary.
Clinical Implications
The Neuromate robotic system offers a viable alternative to the traditional stereotactic frame for DBS electrode implantation with comparable accuracy and clinical outcomes. However, clinicians should anticipate longer surgical times when using the robotic technique. The use of intraoperative imaging may be reduced as experience with the robotic system increases.
Conclusion
Robotic-assisted DBS surgery using the Neuromate system is as effective and safe as the conventional stereotactic frame method, though it currently requires longer operative times. This supports the integration of robotic technology into functional neurosurgery for movement disorders.
