At a recent Cantina luncheon, conversation among five shoulder surgeons concluded that shoulder surgeons are becoming divided with respect to their approaches to arthritic shoulders with glenoid retroversion: there are the “acceptors” and
The “correctors”.You can also find out more about the following: Acceptors The glenoid should only be reaming enough to produce a smooth concavity corresponding to the rear of the glenoid. The Correctors If possible, reduce the glenoid retroversion by 15 degrees or less using components that are posteriorly enhanced, a “high-side” anterior reaming or posterior bone graft.
You can also find out more about the following: Acceptor This approach uses only standard plain radiographs. It may also use anteriorly eccentric humeral heads and rotator-interval plications if there is excessive decentering of the posterior limb at surgery.
In contrast, the Corrector A preoperative CT scan is usually required, as well as three-dimensional planning and a way to carry out the plan during surgery, such a patient-specific instrumentation or computer guided.
In terms of clinical outcomes, the literature to date has not demonstrated a superiority in either approach for arthritic shoulder with a retroverted elbow.
