Abstract: An exemplary system and method that non-invasively assess the effusion state of a joint via the use of a non-invasive measurement device. The measurement device actively interrogates the bone connected to the joint and nearby tissue with mechanical or acoustic energy by applying an impulse or vibratory mechanical or acoustic energy into the bone to assess the response of the bone at its connecting joint and its proximate tissue. The measurement device may additionally interrogate the bone connected to the joint and nearby tissue with electrical energy by applying an impulse or vibratory electrical energy into the joint (e.g., knee) or its nearby tissue to assess the electrical response of the joint and its proximate tissue. In some embodiments, the sensors employ both mechanical interrogation and electrical interrogation of the joint for the non-invasive assessment, e.g., for bioimpedance characteristics of the tissue and joint.

Abstract: Image-guided implant placement as a function of a determined axial rotation of a pelvis. At least one pelvic image presenting a two-dimensional lateral view of a pelvis and at least one pelvic image presenting a 2-D antero-posterior view of the pelvis are processed, including to measure at least one of distances, angles, and areas based on a plurality of identified anatomical landmarks. Pelvic axial rotation at the time of the 2-D AP image is determined, as a function of calculations associated with the at least one of distances, angles, and areas. Information associated with the determined pelvic axial rotation is provided.

Abstract: A system and method provide for image-guided implant placement as a function of at least one intraoperative image during a surgical procedure. At least one computing device is configured by executing code stored in non-transitory processor readable media to process at least one preoperative image to assess axial rotation and/or sagittal pelvic inclination. Further, as a function of a plurality of identified anatomical landmarks in the at least one preoperative image, at least one of distances, angles, and areas is measured. Thereafter, as a function of calculations associated with the at least one of distances, angles, and areas, axial rotation associated with at least one image is measured. Thereafter, at least one value associated with placement of an implant during the surgical procedure is adjusted and information associated therewith is provided via a graphical user interface.
