Publication number: 20070287910Abstract: Devices and processes for use in computer aided or computer navigated surgery include one or more locator and locking mechanisms and mating parts, or, alternatively, one or more adjustable locking structures interposed between an indicium and an item to be used during surgery such as a body part, tool, implant, trial or other structure or component. After the indicia have been registered into the system and surgery begun, it is sometimes desirable to remove and reattach the indicia for better access to the surgical sight, to avoid contamination of the indicia, or to accommodate other surgical needs. Locator and locking mechanisms and mating parts according to various embodiments are designed to be easily removable and accurately reattached so that the indicia can be repositioned relative to the item without the need to reregister the indicia into the system relative to the item.Type: ApplicationFiled: April 14, 2005Publication date: December 13, 2007Inventors: Jody Stallings, Lauralan Terrill-Grisoni, Kevin Raburn

Patent number: 6712823Abstract: An apparatus for guiding the resection of the head of a humerus is provided. The apparatus includes a base, a cut block, and a stylus. The guide is used in connection with a reamer or other tool that is inserted into the intramedullary mayal of the humerus with the shank of the reamer extending superiorally above the head of the humerus to establish the axis of the humerus. The base is in rotatable connection with the reamer. The cut block is removably attached to the guide and has a component for receiving a saw blade. The stylus attaches to the cut block, preferably by engaging the component for receiving the saw blade, and extends around the articular margin of the humeral head to aid in setting height and version.Type: GrantFiled: January 11, 2002Date of Patent: March 30, 2004Assignee: Wright Medical Technology Inc.Inventors: N. Kelley Grusin, Lauralan Terrill-Grisoni, Charles Sorbie, William J. Mallon, Stuart Patterson, Christopher Jobe

Publication number: 20040006392Abstract: A series of humeral stems, each stem including an axial bore and longitudinal slots along the distal end to allow for distal compression. The compression force necessary to compress the distal diameter of each stem varies by stem diameter. Thus, as the stem diameter increases through the series, the compression force decreases. The axial bore and longitudinal slots together form a series of stem segments that assume the shape of the medullary canal, reducing the force exerted upon the canal by the humeral stem.Type: ApplicationFiled: March 25, 2003Publication date: January 8, 2004Inventors: N. Kelly Grusin, Lance Wolf, Lauralan Terrill-Grisoni, Christopher Jobe, Charles Sorbie, William J. Mallon, Stuart Patterson
