Fragility fractures of the pelvis are becoming increasingly important in an ageing society. However, they are under-represented in the current research literature. In particular, unstable bilateral fragility fractures of the sacrum (FFP IVb) benefit from surgical treatment, but individual fracture patterns need to be considered in the surgical decision. This study describes the sacral anatomy in patients with FFP IVb pelvic fractures, with particular emphasis on the identification and evaluation of possible trans-sacral screw corridors, with particular emphasis on the transverse fracture components. ⋯ III.

Boxing is a sport well-known for the risk of injury. However, the epidemiology of boxing-associated fractures has not been well studied. This study aims to report the characteristics of boxing fractures that lead to presentation to the emergency room and evaluate the demographics and practices of the patients to prevent these injuries. ⋯ Hand fractures were the most common type of BAF. Males had significantly more BAFs, although the incidence of BAFs in females increased significantly since 2013. Fractures mainly occurred in recreational places, but from 2020-2022, most occurred at home. This shift coincided with the COVID-19 pandemic, suggesting increased home sparring. These findings emphasize the need for further research into protective measures and injury prevention in boxing.

Femoral neck fractures, particularly Pauwels type II and III, pose significant challenges due to their vertical instability and susceptibility to complications such as non-union and avascular necrosis (AVN). Medial buttress plates (MBPs) have emerged as a promising adjunct in fixation, offering biomechanical advantages by neutralizing shearing forces and enhancing stability. However, the clinical efficacy of MBPs across different fixation techniques, plate configurations, and positioning remains unclear. ⋯ MBPs are a valuable adjunct in managing Pauwels type II and III femoral neck fractures, providing favourable outcomes with low rates of failure and complications. The combination of MBPs with various fixation techniques has shown promising results, highlighting the potential for improved stability and outcomes. Further research is needed to optimize plate size, screw type, positioning, and the role of MBPs in augmenting fixation techniques for these challenging fractures.

The repair of critical-sized bone defects represents significant clinical challenge. An alternative approach is the use of 3D composite scaffolds to support bone regeneration. Hydroxyapatite (HA) and tri-calcium phosphate (β-TCP), combined with polycaprolactone (PCL), offer promising mechanical resistance and biocompatibility. ⋯ The TGF-β/BMP pathway study showed the HA/TCP+ES group increased BMP-7 gene expression at 30 and 60 days, and also greater endothelial vascular formation. Moreover, the HA/TCP and HA/TCP+ES groups exhibited a bone remodeling profile, indicated by RANKL/OPG ratio. HA/TCP scaffolds with ES enhanced vascular formation and mineralization initially, while modulation of the BMP/TGF pathway maintained bone homeostasis, controlling resorption via ES with HA/TCP.

Injuries and violence are among the most prominent public health problems in the world. As well as being a leading cause of mortality - particularly among children and young adults - many of the millions of non-fatal injuries result in life-long disabilities and health consequences. The aim of this study was to estimate the prevalence of unintentional injuries and violence, and their associated factors among high school students. ⋯ This study demonstrated that the prevalence of unintentional injuries and violence among high school students is a major public health problem in Turkey. This study results can have important implications for school administration, parents, and policymakers alike to plan appropriate anti-violence strategies and interventions.
