Anteriorly unstable trabeculated metal prosthesis with rocking horse glenoid loosening

Here's another example of an anteriorly unstable trabeculated metal prosthesis referred to us for revision to a reverse because of refractory anterior instability, failed subscapularis reconstruction, and rocking horse loosening of the glnoied. See our most recent post (link here).





This was revised to a reverse. Because, as is often the case in revising an ingrowth humeral component the tuberosity cracked on humeral component removal, some proximal cement was needed to assure rotational stability,


By contrast, the typical reverse with intact tuberosities can usually be stabilized with impaction grafting alone.
