Background: Glenoid support is critical for stability of the glenohumeraljoint.
2
This relationship permits the large range of motion normally seen in the glenohumeraljoint.
3
The glenohumeraljoint is innately complex and comprised of both static and dynamic stabilizers.
4
Over the time frame of the study, there was radiographic evidence of glenohumeraljoint-space narrowing.
5
A detailed radiographic analysis was performed to evaluate glenohumeral subluxation, glenoid bone loss, and the glenohumeraljoint space.
6
The development of glenohumeraljoint space narrowing is a turning point that indicates a risk of rapid joint destruction.

This article introduces our preferred approach to diagnostic arthroscopy of the glenohumeraljoint and subacromial space with needle arthroscopy and small-bore instruments.
8
Patients younger than 55 years with degenerative conditions of the glenohumeraljoint represent a unique population that can be treated with shoulder arthroplasty.
9
The purpose of this study was to evaluate prospectively the findings during shoulder arthroscopy in patients with recurrent anterior instability of the glenohumeraljoint.
10
As this prospective study shows, multiple morphologic changes are associated with instability of the glenohumeraljoint; there is no single cause for an unstable shoulder.

Results: The hyperplastic synovium of the anterior capsule obstructed the communication between the SSB and the glenohumeraljoint cavity at 2 and 3 weeks.
