Publication number: 20180263790Abstract: A tool and method for locating a proper position for a portal incision for hip arthroplasty, the tool having at least one generally straight body defining an axis, the generally straight body having a slot at one end, the slot being angled at an approximately 45 degree angle relative to the axis of the generally straight body, the slot configured to receive a cutting member or guide tool. A second generally straight body may be connected to the first generally straight body to form a right angle. If the lengths of the two generally straight bodies are substantially equivalent, then when the second generally straight body is inserted into the acetabulum, the first generally straight body positions the slot in the proper location such that sliding a guide tool or cutting member through the slot allows a portal incision to be created in the proper location. In some embodiments, the generally straight bodies may have adjustable lengths.Type: ApplicationFiled: April 8, 2016Publication date: September 20, 2018Applicant: Crescent H TrustInventor: Brad L.

Publication number: 20170202564Abstract: A method for accurately positioning the acetabular cup in a minimally invasive total hip arthroplasty (THA), comprising the steps of (a) placing the cup in roughly the correct position in the acetabulum using a acetabular component placement tool, (b) taking a first abduction reading and a first anteversion reading using a gyroscopic positioning unit aligned with the acetabular component placement tool, (c) taking an image of at least a portion of the cup using a radiography unit, (d) using the image to determine the actual orientation of the cup and required position of the cup to properly orient the acetabular component, (e) incrementally altering the position of the cup by using a striking tool, (f) taking new abduction and anteversion readings using the gyroscopic unit to determine the relative movement of the cup caused by the tapping, and (g) repeating any of the steps as necessary.Type: ApplicationFiled: April 4, 2017Publication date: July 20, 2017Applicant: Crescent H TrustInventor: Brad L.

Publication number: 20170189202Abstract: A tool and method for locating a proper position for a portal incision for hip arthroplasty, the tool being a tubular body having a first portion defining a first axis, a second portion defining a second axis non-parallel to the first axis, the second portion having a directional tool and a lead coaxially aligned, wherein when the tubular body is placed adjacent to an acetabulum with the directional tool aimed at the acetabulum and perpendicular to a plane of the face of the acetabulum, the lead points to location on the skin that would be the proper location for the portal incision. The lead may have a blunt tip, a cutting instrument, or an opening through which a flexible tool can be inserted to forge a path towards the proper location for the portal incision.Type: ApplicationFiled: September 12, 2016Publication date: July 6, 2017Applicant: Crescent H TrustInventor: Brad L.
