Abstract
Systems and methods for anatomical alignment are disclosed herein. In some embodiments, the systems and methods can provide accurate and continuous intraoperative validation of anatomical alignment, e.g., of the spine, hips, pelvis, and/or shoulders. An exemplary system can include a sensor and marker arrangement for measuring coronal imbalance. Another exemplary system can include a sensor and marker arrangement for shoulder or pelvic leveling. Yet another exemplary system can include a mechanical frame for establishing a simulated ground plane and projecting a plumb line from the simulated ground plane.
Claims8
A method for assessing anatomical alignment, comprising:
- attaching, during a surgical procedure, a first range finder component at a first location on a patient;
- attaching, during the surgical procedure, a second range finder component at a left anatomy of the patient with respect to a sagittal plane of the patient;
- attaching, during the surgical procedure, a third range finder component at a right anatomy of the patient with respect to the sagittal plane of the patient;
- measuring, using a processor, a first time of flight of a first signal between the first and second components;
- measuring, using a processor, a second time of flight of a second signal between the first and third components;
- and
- comparing, using a processor, the first and second times of flight to determine an anatomical alignment of the left and right anatomies of the patient,
- wherein the first location is medial to least one of the second and third range finder components such that the first location is closer to a midline of the patient than both of the second and third range finder components.
