Which is the best option for glenoid baseplate fixation in the elderly?
Here are some variables to consider:
1. A 6.5 mm screw is often used. Will this gain sufficient purchase in the elderly?
2. A central post has the potential of ingrowth but has a larger diameter of a 6.5 mm screw.
3. A revision of a post will need at least a 9.5 mm screw or a completely different hole position
4. The dimensions of the glenoid vault will determine post perforation which may not be desirable
