Abstract
NeedDuring deep brain stimulation (DBS) surgery, the base ring of the burr hole is the main structure that anchors the DBS lead. A discrepancy between the burr hole size and ring base renders the ring unstable which in turn compromises lead stability. Burr hole size mismatch is often seen in resource-poor countries where advanced perforators, that make exact size holes are not available.Technical SolutionWe describe a simple, cost-effective technique, the screw-lock method. When there is a mismatch, titanium self-tapping screws are inserted through the holding holes of the base ring into the skull with immediate and stable fixation.Proof of ConceptThis technique not only immediately secures the base ring to the skull but also prevents accidental displacement of the DBS lead.Next StepsThe titanium screws can be included in the burr hole ring set in commercially available products. A new type of expandable burr hole rings can be designed to fit any size of burr hole.ConclusionThis is an effective method to stabilize the burr hole base ring and the DBS lead.
期刊介绍：
Surgical Innovation (SRI) is a peer-reviewed bi-monthly journal focusing on minimally invasive surgical techniques, new instruments such as laparoscopes and endoscopes, and new technologies. SRI prepares surgeons to think and work in "the operating room of the future" through learning new techniques, understanding and adapting to new technologies, maintaining surgical competencies, and applying surgical outcomes data to their practices. This journal is a member of the Committee on Publication Ethics (COPE).
