Hip surgery systems and methods
Orthopedic systems and methods are provided for use in preparing joints for implants. Specifically, hip preparation systems and methods are disclosed which can include a surgical orientation device. The hip preparation systems and methods can be used, for example, to orient the hip during the procedure, determine the orientation of an anatomical plane or planes, and orient a prosthetic component or components.
1. A method for assisting a surgeon, comprising:
providing an orientation device comprising a display and at least one inertial sensor;
positioning the orientation device to register the orientation device relative to the operating table;
coupling the orientation device to a surgical instrument;
positioning the orientation device and the surgical instrument within the surgical field;
monitoring the orientation of a prosthetic component coupled to the surgical instrument as the prosthetic component is moved and adjusted within the acetabulum; and
aligning the prosthetic component based on on-screen graphics presented on the display of the orientation device.
2. The method of claim 1 , wherein the on-screen graphics comprise instructive images.
3. The method of claim 1 , wherein the on-screen graphics comprise textual instructions.
4. The method of claim 1 , wherein the on-screen graphics comprise orientation data received from the at least one inertial sensor.
5. The method of claim 1 , wherein the on-screen graphics comprise an indicator to aid the user in maintaining a particular orientation.
6. The method of claim 1 , wherein the on-screen graphics comprise a numerical reading or measurement.
7. A method for assisting a surgeon, comprising:
providing an orientation device comprising a display and at least one inertial sensor;
coupling the orientation device to a first location on the patient's pelvic region;
recording a measurement with the orientation device at the first location;
coupling the orientation device to a second location on an acetabular cup impactor, wherein the orientation device is transitionable between the first location and the second location;
positioning the orientation device and the acetabular cup impactor within the surgical field;
monitoring an orientation of the acetabular cup impactor as the acetabular cup impactor is moved.
8. The method of claim 7 , wherein the display of the orientation device provides on-screen graphics.
9. The method of claim 7 , wherein the display of the orientation device provides textual instructions.
10. The method of claim 7 , wherein the orientation device allows a user to confirm completion of the surgical procedure step.
11. The method of claim 7 , wherein the orientation device allows a user to enter data.
12. The method of claim 7 , wherein the orientation device allows a user to verify a position of the surgical instrument.
13. The method of claim 7 , wherein the at least one inertial sensor provides a measurement relative to a reference plane.
14. The method of claim 7 , wherein the at least one inertial sensor provides a measurement relative to gravitational zero.
15. A method for assisting a surgeon, comprising:
providing an orientation device comprising a display and at least one inertial sensor;
coupling the orientation device to a pelvis of a patient;
coupling the orientation device to a surgical instrument after coupling the orientation device to the pelvis of the patient;
wherein the orientation device generates orientation data corresponding to the monitored orientation of the orientation device;
aligning a prosthetic component based on orientation data corresponding to the monitored orientation of the orientation device, wherein display provides an angle measurement;
coupling the orientation device to the pelvis of the patient after aligning the prosthetic component; and
adjusting the prosthetic component after aligning the prosthetic component.
16. The method of claim 15 , wherein the display provides an interactive graphical indicator of orientation, wherein the interactive graphical indicator of orientation is a level.
17. The method of claim 15 , wherein the at least one inertial sensor provides measurements relative to a reference plane.
18. The method of claim 15 , wherein the at least one inertial sensor provides measurements relative to gravitational zero.
