The B2 retroverted glenoid is an augmented glenoid needed?

In performing a total shoulder for the B2 retroverted glenoid with posterior decentering, some surgeons prefer to normalize glenoid version with anterior glenoid bone reaming, posterior bone grafting or posteriorly augmented glenoids, we have found that most cases can be managed with a standard glenoid component accepting the retroversion as described in this link.

Here is a recent case of a B2 glenoid with preoperative retroversion of 25 degrees and posterior decentering.

A total shoulder arthroplasty was performed with a standard glenoid component without changing the glenoid version. Note the re-centering of the humeral head.

 This approach is in contrast to the use of special posteriorly augmented glenoid components as discussed in a recent article (see this link). Here ar examples of augmented components.

Here is an example from that article. 

We suggest that the minor degree of retroversion shown here could be well managed with a standard, non-augmented glenoid component as shown above.
