Furthermore, use of a glenosphere with a center of rotation 10 mm lateral to the glenoid can be utilized with a glenoid baseplate secured with a combination of locked and non-locked screws without compromising the fixation necessary for ingrowth.
We hypothesized that glenoid baseplate micromotion would be sufficiently minimized using all combinations of locked and non-locked peripheral screws.
Hybrid peripheral screw fixation using combinations of locked and non-locked screws provides secure glenoid baseplate fixation using a polyurethane bone substitute model.
In summary, hybrid peripheral screw fixation using combinations of locked and non-locked screws provides secure glenoid baseplate fixation using a polyurethane bone substitute model.
We aimed to determine if different combinations of locked and non-locked screws significantly alter acute glenoid baseplate fixation in a laboratory setting.
The purpose of this study was to evaluate initial glenoid baseplate fixation using a variety of combinations of locked and non-locked peripheral screws.
The concept of hybrid fixation, where combinations of locked and non-locked screws are used together, has been a longstanding feature used in locked plate osteosynthesis and has been shown to be biomechanically similar while also providing the potential benefits of compression or aiding with reduction [24, 25, 26, 27, 28].
For this study, we evaluated baseplate fixation using four combinations of locked (5-mm diameter) and (3.5-mm diameter) non-locked peripheral screws in seven (n = 7) cylinders per fixation group—(1) 1 locked screw + 3 non-locked screws (1-locked), (2) 2 locked screws + 2 non-locked screws (2-locked), (3) 3 locked screws + 1 non-locked screw (3-locked), and (4) 4 locked screws (4-locked).
Most important, he was instrumental in persuading President Theodore Roosevelt of the feasibility of a high-level canal using a combination of locks and a dammed lake.
When passengers, flight attendants and pilots are all potential enemies, what combination of locks and protocols can possibly work?
