Summary: The study found that there was no significant difference in the removal torque of augmented versus non-augmented screws during implant removal surgery. However, significantly more screws failed in the augmented group. When implanting a femoral component for knee arthroplasty, the presence of broken screws and residual cement did not significantly affect initial anchorage.

Summary: The study aimed to compare the difference in fracture gap compression and pull-out force between cement-augmented sacroiliac screw fixation using partially and fully threaded screws. The results showed that partially threaded screws with cement augmentation can narrow the fracture gap even in osteoporotic bone, with resistance against pull-out force not significantly lower compared to fully threaded screws.

Summary: This study compares the construct stability of cement augmented sacroiliac screws using two different cementation sites in a biomechanical fragility fracture model of the pelvis. The results demonstrate that cement augmentation at the lateral mass of the sacroiliac screw provides less fragment and screw displacements compared to cement augmentation at the center of the vertebral body of S1.

Summary: This study compares the pull-out strength of cement augmented screws between inserting screws in the working phase or hard phase of bone cement. The results show that screws inserted in the working phase have higher pull-out strength. Therefore, it is recommended to perform internal fixation before cementation after curettage of aggressive bone tumors.

Summary: This study found that simultaneous treatment of injured patients is rare. Individuals treated in parallel with other patients were more often admitted to level-one trauma centers compared with individual patients. Although diagnostics take longer, treatment principles and mortality are equal in individual admissions and simultaneously admitted patients. More studies are required to optimize health care under these conditions.

Summary: This study compared the clinical outcomes of operative and conservative treatment for patients with acromial or scapular spine fractures after reverse total shoulder arthroplasty (RTSA). The results showed no significant differences between the two treatment methods in terms of Constant score, subjective shoulder value, or range of motion. However, both treatment options yielded inferior results compared to RTSA without postoperative acromial fractures. Conservative treatment may be the preferred option for acromial fractures after RTSA until better surgical methods are developed.
