This is peak at a project I’m doing with real-time assessment of scapula dynamics after reverse arthroplasty using the Alyve system (showmotion). I believe this is the next level of understanding how reverse work, above and beyond preop planning, navigation, and augmented reality in the OR. We’ve never before been able to assess real time scapula function like this! Glenohumeral amplitudes alone do not explain the results we get, and it’s much more complicated than the moment arm of the deltoid, lateralization and medialization of the glenosphere, and passive motion arcs. Kudos to the Alyve team for building a next level assessment tool for the shoulder! #alyve #showmotion #ases #shouldersurgery #reversearthroplasty #shoulderarthroplasty
I want to learn more about this.

8moHey Brett Sanders this is a good and interesting presentation. In the pre-op, it is clearly visible that the unstable tilt becomes negative (anterior) and seriously limits mobility. This is mainly attributed to the upper trap activity. In the post-op phase, it is interesting to note how the patient regains protraction but to do this she needs to over tilt (this is very typical of a patient having a reverse). In the final check instead a normalization of the tilt comes together with a nicer Pr-Re curve and it is noticeable the stabilization in the first degrees in upward rotation. It is really amazing the plot of the SHR track and the comparison to the contralateral. The difference in ratio and smoothness is really evident and provides a completely new and powerful way to track the patient's evolution and status. The rough pattern in the contralateral is a confirmation of the unstable control of the scapula. The tracking of the SHR is a very important variable to assess the proper shoulder function together with the protraction angle at rest. An optimal ratio con be targeted to maximize the outcome and optimize the function having a more homogeneous result.
