For shoulder surgeons, it is difficult to treat severe glenohumeral Osteoarthritis (GHOA), with posterior glenoid erode.
The authors of Anatomic Total Shoulder Arthroplasty with All-Polyethylene Glenoid Component for Primary Osteoarthritis with Glenoid Deficiencies evaluated 66 shoulders with type-B2 glenoids (n = 40) or type-B3 glenoids (n = 26) undergoing total shoulder arthroplasties with a non-augmented glenoid component inserted without attempting to normalize glenoid version.
Scores on the Simple Shoulder Test were improved
Scores on the Simple Shoulder Test were improved
Preoperatively, 3.2 to 9.9 days after surgery with a mean follow-up of 2.8 for type-B2 Glenoids
From
3.0 preoperatively to 8.4 postoperatively with a mean follow-up of 2.9 for type B3 glenoids.
These results were no different from those achieved for shoulders with other type of glenoid.
Postoperative glenoid version was not significantly different (p > 0.05) from preoperative glenoid version.
The mean humeralhead decentering of the glenoid facial was reduced
Type-B2 glenoids: -14% preoperatively, -1% postoperatively
For type-B3 Glenoids, from -4% preoperatively up to -11% postoperatively.
