Progressive glenoid bone loss and humeral head subluxation occur in primary glenohumeral osteoarthritis (GHOA), but less is known about the rate and pattern by which this occurs. The purpose of this study was to determine how glenohumeral subluxation and glenoid bone loss changed over time in shoulders that underwent arthroplasty and had been evaluated with radiographs at 1 or more time points over the 5-15 years before arthroplasty.
In primary GHOA, humeral head subluxation and glenoid bone loss do progress over time, but not universally and not always through the same pathway.
Level of evidence: Level IV; Case Series; Prognosis Study. Copyright remains with the authors and publisher.
