Inside-out guide for hip replacement method
First Claim
1. A method of creating a portal incision from inside a hip in a hip arthroplasty, comprising:
- creating a main incision in a skin in the hip to expose an acetabulum;
inserting a tubular body into the main incision in preparation for determining a proper location for the portal incision, the tubular body, comprising;
a first portion defining a first axis;
a second portion connected to the first portion, the second portion comprising a directional tool and a lead, wherein the lead defines a second axis and wherein the first and second axis are non-parallel;
aligning the directional tool to be perpendicular to a face of the acetabulum so that the lead points towards the proper location for the portal incision;
feeding a flexible tool from outside the hip into the first portion to exit the second portion inside of the hip directed towards the proper location for the portal incision from inside the hip;
advancing the flexible tool through non-critical tissues to create a path towards the proper location for the portal incision; and
creating the portal incision through the skin at the proper location identified by the flexible tool.

Abstract
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.
