Glenoid morphology rather than version predicts humeral subluxation: a different perspective on the glenoid in total shoulder arthroplastyHeinz R Hoenecke Jr 1, Lisa M Tibor, Darryl D D'Lima
Glenoid version did not correlate with humeral subluxation. The highest frequency of posterior subluxation was noted in biconcave glenoids.

Shoulder & ElbowIs there a correlation between humeral osteoarthritis and glenoid morphology according to Walch?Philipp Vetter

Increased humeral osteophyte length correlated with a higher grade of glenoid morphology (A1-A2-B1-B2-B3) according to Walch (r = 0.672; p < 0.0001).
​The criteria of humeral OL and HH morphology are associated with increasing glenoid retroversion, posterior humeral subluxation, and eccentric glenoid wear. Therefore, humeral radiological parameters might hint at the morphology on the glenoid side.

In a small sample size, I have found a corrrelation between posterior humeral subluxation and glenoid version
