BackgroundDuring Leksell frame-based stereotaxy the lateral trajectory can be obstructed by the arc supports at certain combinations of the X-coordinate and arc angle.ObjectiveTo provide a matrix with usable and prohibited combinations of the X-coordinate and arc angle to faciliate finding lateral stereotactic trajectories with the Leksell frame in standard configuration.MethodsVarious combination settings of the X-coordinate and arc angle were tested for a Leksell Multi-Purpose Stereotactic Arc mounted on a Leksell Coordinate Frame G.ResultsA matrix of usable and prohibited combinations of the X-coordinate and arc angle is provided.ConclusionsThe matrix will help to facilitate surgical work flow during stereotactic procedures involving the Leksell frame.
