One long posterior fixation post for Leksell® Coordinate Frame G. New insulating design well suited for high tesla MR scanners and high frequency MR sequences. A sterile, single-use insert is used to effectively insulate the fixation screw from the post, thereby minimizing the occurance of radio frequency generated thermal effects when using high tesla MR scanners and high frequency MR sequences.

The rounded slimmed top allows for more space in tight MRI head coils and increases the available treatable volume for Gamma Knife® surgery.

The risk of persistent cross-contamination is reduced when Insulated Fixation Posts are used together with Disposable Fixation Screws since the insert provides a single-use interface between the patient and the frame.
