Publication number: 20210361297Abstract: A surgical positioning system including a rotation guide slide and a rotation guide pointer configured to be coupled to the rotation guide slide. The rotation guide pointer includes a base and a pointer extension. The base includes protrusion and a hole extending through the base and the protrusion where the protrusion is sized and configured to be received within a channel such that the rotation guide pointer can translate parallel to a plane defined by the first side of the rotation guide slide. The hole is sized and configured to receive a screw to fix the position of the rotation guide pointer relative to the rotation guide slide, with the protrusion configured to expand when the screw is advanced in the hole.Type: ApplicationFiled: August 5, 2021Publication date: November 25, 2021Applicant: Wright Medical Technology, Inc.Inventors: Ramon Luna, Matthew D.
