Abstract: Systems and methods for calculating external bone loss for alignment of pre-diseased joints comprising: generating a three-dimensional (“3D”) computer model of an operative area from at least two two-dimensional (“2D”) radiographic images, wherein at least a first radiographic image is captured at a first position, and wherein at least a second radiographic image is captured at a second position, and wherein the first position is different than the second position; identifying an area of bone loss on the 3D computer model; and applying a surface adjustment algorithm to calculate an external missing bone surface fitting the area of bone loss.

Abstract: A system for establishing an intramedullary path includes a body sized and configured to be received within a resected bone space. The body defines a first aperture that extends through the body and is sized and configured to receive a surgical tool therethrough. A first bone engaging structure extends from the body in a first direction and includes a first surface that is complementary to a surface topography of a first bone. When the first surface of the bone engaging structure engages the surface topography of the first bone to which the first surface is complementary, an axis defined by the first aperture is substantially collinear with a mechanical axis of the first bone.

Abstract: A resection guide locator includes a bone engagement portion with surfaces that are complementary to the surface topographies of a bone to be resected during surgery. A housing includes a socket defined by a resilient annular wall that is sized and arranged so to accept a resection guide by press-fit to thereby position and hold the resection guide within he socket. The resection guide is maintained in a predetermined, preferred position while the surfaces are releasably locked in position on the bone. A method is disclosed for forming and using the resection guide locator.

Abstract: A method includes mapping a contoured surface of at least one bone onto a digital model of a resection guide locator using a processor to create a digital model of a customized resection guide locator and manufacturing the customized resection guide locator. The customized resection guide locator includes a complementary surface of the at least one bone and a wall having a shape that is complementary to an outer profile of a resection guide and defining a pocket. A first elongate slot and at least one first hole are positioned within the pocket such that the first elongate slot aligns with a second elongate slot defined by the resection guide and the at least one first hole aligns with at least one second hole defined by the resection guide when the resection guide is received within the pocket of the customized resection guide locator.

Abstract: A method of providing a minimally invasive hip arthroplasty in conjunction with a main incision formed through a patient's skin and soft tissue in the patient's hip, including providing an instrument having a main body and an arrangement for guiding the formation of a portal incision and a small path to the patient's acetabulum along an impaction axis. A trocar is placed through a guide ring on an arm of the instrument to form the portal incision and small path. Impaction of an acetubular shell is carried out along the impaction axis thus formed.
