The glenoid fossa is involved in approximately 10% of all scapular fractures.Glenoid fossa incongruity is surprisingly well tolerated.Surgery is recommended when 20% or more of the anterior glenoid fossa is involved.Glenoid rim fractures often lead to chronic shoulder instability.Unstable glenoid neck fractures need surgical treatment and stable fractures can be treated conservatively.CT examination with 3D reformations of the glenoid fossa has improved insight into fracture morphology and fracture patterns and is very helpful for clinical decision makers.
