Despite the plausibility that diabetes may increase the risk of motor vehicle crashes (MVCs) due to various diabetes related complications and co-morbidity, findings from epidemiological studies on the relationship between diabetes and MVCs remained inclusive mainly due to heterogeneity in the study design and failure to complete consideration of potential confounders. This study re-visited this putative association with an improved study design. ⋯ T2D diagnosis was associated with a moderate but significant increase in the risk of MVCs among scooter drivers, but not among car drivers.

We sought to determine if the magnitude of anterior physeal separation (APS) in slipped upper femoral epiphysis was a predictor for the subsequent development of avascular necrosis (AVN). Anterior Physeal Separation (APS) is defined as the distance between the anterior lip of the bony capital epiphysis and the lateral corresponding point of the adjacent bony metaphysis on the Lauenstein radiographic view. It represents hinging of the posterior aspect of the metaphysis with the anterior epiphysis lifting away from its adjacent metaphysis, indicating instability and potential vulnerability of the vessels. ⋯ APS is sensitive, specific, accurate and reliable for the association with AVN in SUFE. Its values closely reflect the high AVN rates seen in acute and unstable SUFE. This risk is greatest if the magnitude of APS exceeds the critical value of 7.5 mm.

Walkability scores have been developed to measure how well the characteristics of the physical environment support walking. However, because pedestrian safety is not taken into account, areas that have higher Walk Scores could be associated with more walking and also more pedestrian-related injury. We aimed to explore the association between Walk Score and pedestrian-related injury in Sydney. ⋯ For the majority of the population, built environment characteristics that are considered to make walking attractive also make it safer, offsetting any exposure-related increase injury risk. However, this is not the case for people aged ≥ 19 years, and those living in socioeconomically disadvantaged areas. Incorporating measures of pedestrian safety in walkability scores may create an impetus to ensure that the built environment is designed to support the safety of pedestrians from these groups.

Displaced acetabular fractures in the elderly present significant treatment challenges. The 'fix and replace' concept involves open reduction and internal fixation of the acetabulum, providing bony stability to accept the press-fit of an acetabular cup, with a cemented femoral stem. This allows early mobilisation and the advantages this confers. This study of 57 patients treated with fix and replace describes our technique, outcomes, and survival analysis. ⋯ While fix and replace is conceptually attractive, this medically complex patient group requires considerable support peri‑ and post-operatively. Further studies are required to provide clinicians with more information to decide on how best to provide a holistic management strategy for such injuries in this frail patient cohort.

Fragility fractures of the pelvis (FFP) are becoming increasingly common. Percutaneous sacroiliac screw fixation is an accepted and safe treatment method for FFP. Augmentation is an option to optimize fixation strength of the screws. This study aims to compare patient mobility and the occurrence of complications after operative treatment of FFP utilizing two different augmentation techniques. ⋯ Both augmentation techniques have a low complication rate and are safe methods to maintain patients' mobility level. The authors advocate early consideration of surgical treatment for patients with FFP. Augmentation can be considered a safe addition when performing percutaneous sacroiliac screw fixation.
