One such method includes simulating an insertion point and an orientation of a simulated surgical hardware installation on a diagnostic representation of the bone, and then using an electronic device to align an instrument for inserting a surgical hardware installation at a desired orientation through an insertion point by indicating when an orientation of the electronic device is within a threshold of the simulated orientation. ## Claims ### Claim 1 A method for assisting with orienting a medical device at a desired location, the method comprising: displaying, on an electronic device, by one or more processors, an image of a representation of a location at or adjacent the desired location; simulating, by one or more processors, a position of the medical device relative to the image to determine a first desired orientation of the medical device relative to a plane of the image; positioning the medical device at or adjacent the desired location; positioning the electronic device at a reference position relative to the medical device; determining, by one or more processors, an orientation of the electronic device using an orientation sensor; and determining, by one or more processors, when the orientation of the electronic device is positioned at or about the first desired orientation of the medical device relative to the plane of the image. ### Claim 2 (depends on 1) The method of claim 1, further comprising: determining, by one or more processors, when the electronic device is positioned at or about a second desired orientation of the medical device relative to a second plane of a second image; and outputting a notification when the electronic device is positioned at or about the first desired orientation and the second desired orientation. ### Claim 3 (depends on 1) The method of claim 1, wherein the image is a superior view of the desired location, a lateral view of the desired location, or a posterior view of the desired location. ### Claim 4 (depends on 1) The method of claim 1, wherein the image is a pictorial view, an x-ray, a radiograph, a computed tomography scan, or a magnetic resonance image. ### Claim 5 (depends on 1) The method of claim 1, wherein the plane is one of an axial plane, a coronal plane, or a sagittal plane. ### Claim 6 (depends on 1) The method of claim 1, wherein the medical device is a pedicle screw, a steel rod, a stent, an interbody cage, a bone graft, an implant, a gearshift probe, a drill guide, or a drill bit. ### Claim 7 (depends on 1) The method of claim 1, wherein the image includes a representation of at least one or more portions of a body from a group that includes a spine, a joint, a rib cage, a cranium, an artery, a lung, or other portion of the body to receive an implant. ### Claim 8 (depends on 1) The method of claim 1, wherein the electronic device includes two or more computing devices that include one or more processors. ### Claim 9 (depends on 1) The method of claim 1, further comprising creating an opening in a body part for receiving the medical device using an instrument positioned adjacent to the electronic device. ### Claim 10 (depends on 1) The method of claim 1, wherein the orientation sensor comprises at least one or more of a gyroscope, an accelerometer, or an inertial measurement unit. ### Claim 11 (depends on 9) The method of claim 9, wherein the instrument is one of a gearshift probe, a drill guide, or a drill bit. ### Claim 12 (depends on 1) The method of claim 1, wherein determining the orientation of the electronic device is determined with respect to an orientation of a longitudinal axis of the electronic device. ### Claim 13 A method for assisting with orienting a medical device at a desired location, the method comprising: receiving, by one or more processors, a first input from a user specifying a first positioning angle of the medical device in a first image of a representation of a location at or adjacent the desired location; receiving, by one or more processors, a second input from the user specifying a second positioning angle of the medical device in a second image of the representation of the location at or adjacent the desired location, the second image orthogonal to the first image; determining, by one or more processors, a three-dimensional orientation of an electronic device for positioning the medical device based on the first positioning angle and the second positioning angle; and displaying, by one or more processors, a visual indicia on a display device that represents the three-dimensional orientation of the medical device. ### Claim 14 (depends on 13) The method of claim 13, wherein the electronic device and the display device use one or more processors. ### Claim 15 (depends on 13) The method of claim 13, wherein the display device and the electronic device are included in a device. ### Claim 16 (depends on 13) The method of claim 13, wherein the first positioning angle corresponds with a first axis of the medical device and the second positioning angle corresponds with a second axis of the medical device. ### Claim 17 (depends on 13) The method of claim 13, wherein the first positioning angle corresponds with a first axis of an instrument and the second positioning angle corresponds with a second axis of the instrument. ### Claim 18 (depends on 13) The method of claim 13, wherein the first image is an axial view, and the second image is a lateral view. ### Claim 19 (depends on 13) The method of claim 13, wherein the medical device is a pedicle screw, a steel rod, a stent, an interbody cage, a bone graft, an implant, a gearshift probe, a drill guide, or a drill bit. ### Claim 20 (depends on 13) The method of claim 13, wherein the first image and the second image include representations of at least one or more portions of a body from a group that includes a spine, a joint, a rib cage, a cranium, an artery, a lung, or other portion of the body to receive an implant. ### Claim 21 (depends on 13) The method of claim 13, wherein the electronic device includes two or more computing devices that include one or more processors.
