Abstract
Disclosed herein is a surgical guide tool for use in total hip replacement surgery. The surgical guide tool may include a customized mating region and a resection guide.

An arthroplasty jig for use in performing an arthroplasty procedure on a bone of a patient, the bone forming a portion of a ball and socket joint, the bone comprising a head having an articular surface that is bounded by a neck border, a non-articular surface extending distally from the neck border, and a tubercle formed on non-articular surface of the bone, the arthroplasty jig comprising:
- a jig body comprising:
- a first mating surface defined on a bone facing side of the jig body, the first mating surface configured to matingly contact the non-articular surface of the bone in a first location in a customized fashion unique to the patient when the jig body is applied to the bone to perform the arthroplasty procedure;
- a second mating surface defined on the bone facing side of the jig body, the second mating surface configured to matingly contact the non-articular surface of the bone in a second location in a customized fashion unique to the patient when the jig body is applied to the bone to perform the arthroplasty procedure;
- a spaced-apart surface defined on the bone facing side of the jig body and separating the first mating surface and the second mating surface, the spaced-apart surface configured to be recessed from contact with the tubercle when the first and second mating surface matingly contact the first and second locations on the non-articular surface, respectively;
- and
- a saw guide configured to guide a saw in making a resection of the bone, the saw guide extending through the jig body and comprising a preoperatively planned position and orientation relative to the first and second mating surfaces.
