Introduction: Screw tip augmentation with bone cement for fixation of osteoporotic proximal humerus fractures seems to improve stability and to decrease the rate of complications related to implant failure. However, the optimal augmentation combinations are unknown. The aim of this study was to assess the relative stability of two augmentations combinations under axial compression load in a simulated proximal humerus fractures fixed with locking plate.

- The study investigated the impact of different screw tip augmentation combinations with bone cement on the stability of osteoporotic proximal humerus fractures fixed with a locking plate.
- The experimental setup involved testing five pairs of embalmed humeri, examining interfragmentary motion during cyclical loading and evaluating failure under increasing compression force.
- Results showed no significant differences in stability between the two configurations of cemented screws, indicating that the choice of screw configuration does not significantly affect implant stability with low-energy loads.
