In addition, the highest pullout strength was found in combination of cylindrical-solid-full insertion.
The highest pullout strength was the UPS-4 screw, and there was no significant difference in pullout strength among the other screw designs.
Therefore, even though the pedicle screws have been shown to have the highest pullout strength, some authors did not recommend routine use due to a higher risk for vertebral artery injury [ 22].

In the 2.4-/2.5-mm 2.4-/2.5-mm 2.4-/2.5-mme cannulated screw designs had a significantestsigher pullout strength when compared with the solid-core screw (P <.05).
A higher pullout strength was obtained from the inclusion of fibers in the matrix, and 2 vol.% of fibers provided the best performance in all aspects of fiber pullout behavior including average and equivalent bond strengths and pullout energy.
In the testing of 3.0-mm screw test, 1 of the cannulated screw designs showed a significantly higher pullout strength than the other cannulated and solid-core screws that were tested (P <.05).
This increased interface led to significantly higher pullout strength for solid screws.
In the present study, for a given screw design (conical or cylindrical), we report a significantly higher pullout strength for solid screws with retrograde cement pre-filling than for cannulated screws with cement injection using artificial osteoporotic bones.
Battula et al. [ 62] set out to determine what they called the critical pilot hole size, which was defined as the hole size needed to maintain an optimal balance between low installation torque and high pullout strength.
The current testing study also demonstrated that the conical-shaped UPS-4 screw had higher pullout strength than its cylindrical-shaped counterpart, UPS-3, (Table 2 and Figure 3).
The results revealed the following 1) Regardless of the screw outer geometry (conical or cylindrical), solid screws with retrograde cement pre-filling exhibited significantly higher pullout strength than did cannulated screws with cement injection through perforation (p = 0.0129 for conical screws; p = 0.005 for cylindrical screws).
