Why the study?
Do keeled glenoid components compared to pegged components affect the frequency of radiolucencies and incomplete component seating?
Do keeled glenoid components compared to pegged components affect the frequency of radiolucencies and incomplete component seating?
Keeled glenoid components are associated with more frequent radiolucencies and incomplete seating than pegged components.
Answers are grounded in this paper and cite their sources.
May favor pegged over keeled glenoid components; leaves open effects on outcomes and revisions.
Perfectly cementing and seating a glenoid replacement is a difficult task. Radiolucencies and incomplete component seating occur more frequently in association with keeled components compared with pegged components. Surgeon experience may be an important variable in the achievement of a good technical outcome.
