Introduction: Clavicle fractures are routinely encountered in orthopedic clinical practice and have often been the subject of debate when it comes to optimal treatment. Clavicle fracture surgery has come a long way with excellent pre-contoured superior locking plates available for fixation. This study aimed to evaluate a cohort of patients operated for displaced mid-shaft clavicle fractures by open reduction and internal fixation using superior clavicle locking plates.

Palladium (Pd) nanocubes, a type of metallic nanostructure, have demonstrated remarkable optoelectronic properties, garnering significant attention. However, their nonlinear optical characteristics and related device applications remain underexplored. In this study, we report the fabrication of a novel saturable absorber (SA) by depositing Pd nanocubes onto a D-shaped fiber (DF).

Amorphous aerogels with the microscopic nanoscale three-dimensional meshes provide superb platforms for investigating unique physicochemical properties. In order to enhance the physical, thermal and mechanical performances, one efficient and common approach is integrating diverse functional materials. Herein, we report a simple strategy to fabricate the amorphous silicon doped YO aerogels with the post-gelation method under the N/EtOH supercritical atmosphere.

Numerical design has shown that more than 70 MHz repetition rate is achievable in a ring cavity configuration using standard step-index fibers and components. Interest of WDM type filtering on pulse duration is especially shown.
