Which glenoid polyethylene option is typically cemented in place?

The glenoid polyethylene option that is typically cemented in place is the pegged design. This design consists of pegs that provide additional stabilization during cementing, allowing for a strong bond between the implant and the bone. The use of cement in establishing fixation is critical for ensuring long-term stability and appropriate load distribution across the implant.

While the keel design is also used in some systems, it may not always require cementing, as it relies on press-fit fixation in certain cases. The vault lock design allows for a different form of interaction with the bone which does not typically involve the same cementation process. Therefore, while both pegged and keel designs have their applications, the pegged glenoid is distinctively recognized for its dependence on cement for stability in many surgical scenarios.
