Summary: This study explored the anatomical correlation between the femoral neck shaft angle (NSA) and femoral anteversion angle (AA) in patients with developmental dysplasia of the hip. The results showed a positive correlation between NSA and AA in normal and Crowe type I-III hips, suggesting torsion of the proximal femur. This correlation provides a straightforward method to estimate AA based on NSA in these cases.

Summary: The study aimed to investigate the effects of imaging position and sex on NSA measurement and provide reference values. The findings showed no significant difference in NSA between the right and left in standing radiographs, but significant asymmetry was found in supine radiographs. Further research is needed to confirm these results.

Summary: This study investigates whether insects follow Bergmann's Rule and examines the long-term changes in body size of a species of Scarabaeidae beetle in response to rising temperatures in Taiwan. The results show that the beetles' size has increased over time, with a correlation between size and rising yearly temperatures in Taipei populations.

Summary: This article reviews the treatment methods for segmental femoral fractures, including damage control orthopaedics and definitive fixation. The study finds limited comparative evidence between different treatment methods. Additionally, advanced design nailing and plating systems offer improved fixation options.

Summary: This study investigated the relationship between femoral torsion angle (FTA) and femoral bowing angle (FBA) in a southern Chinese population. The results showed that increased FTA led to a greater lateral FBA. This finding has implications for orthopedic surgery, total knee arthroplasty, and patellofemoral pressure distribution.

Summary: The study found that body size of Chinese lizards is larger in warmer regions, but at the assemblage level, size is correlated with multiple climatic factors and correlations vary within different major groups. Phylogenetic analysis revealed that, except for agamids, there is no significant association between body size and climate for lizards.

Summary: The study assessed the reliability of a new technique for measuring neck shaft angle (NSA), finding no significant variability between bilateral NSA in males and females, and supporting the use of this measurement method and contralateral NSA for proximal femur fracture planning.

Summary: This study investigates the links between environmental factors, body size, range size, and extinction risk in rodents. The results show that body size is mainly influenced by vegetative index rather than latitude/temperature and smaller range size relative to body size is associated with increased risk of extinction.

Summary: This study investigated the development and maturation rules of the trabeculae in Ward's triangle and found that it was related to the neck-shaft angle. These findings provide a better understanding of the structure and mechanical characteristics of the proximal femoral trabeculae and improve our knowledge of the mechanism and treatment of proximal femoral fractures.

Summary: The aim of this study was to compare the accuracy of widely used conventional X-ray-based (2D) neck-shaft angle measurements with 3D reconstruction. The study found no significant difference in accuracy between the four examined 2D methods, but the deviation between 2D and 3D results was considerable. Only femoral torsion had a significant influence on the difference. It is recommended to use any 3D imaging method for surgical planning and in uncertain cases.

Summary: Animals often respond to climate change with changes in morphology, but recent studies show that these responses and the resulting fitness consequences cannot be generalized even among related species.

Summary: This study aimed to evaluate the clinical outcomes and risk factors associated with missed diagnosis of ipsilateral femoral neck and shaft fractures. It was found that there was a high rate of missed diagnosis, especially for minimally displaced fractures. CT examination was found to be a protective factor for detecting femoral neck fractures. Avascular necrosis of the femoral head was related to femoral neck fracture displacement, but not delayed diagnosis. The nonunion rate of the femoral shaft was high and requires attention.

Summary: As temperatures rise, there is evidence that species are becoming smaller. This article reviews the role of developmental plasticity in temperature-induced size reductions in birds and highlights insulin-like growth factors as a potential mechanism. It finds that changes in temperature during development can result in shifts in body size in birds, with size reductions being associated with warmer temperatures.

Summary: The study identified a correlation between high-energy femoral diaphyseal fractures (types A3, B, and C) and ipsilateral femoral neck fractures, suggesting that routine additional methods of image investigation may be unnecessary for patients with type A1 and A2 femoral diaphyseal fractures.

Summary: In addition to natural curiosity, science is characterized by a number of psychological processes and perceptions. A speculative theoretical model suggests the evolution of science reflects psychological repercussions of wearing clothes, as it leads to the perception of the natural world as hidden. This perspective proposes that scientific foundations began to develop during the last ice age, with the invention of complex clothing that covered the human body fully.

Summary: The advent of farming and food production sustained a massive expansion of human populations, facilitated socioeconomic and technological developments, and transformed the world's land surface. The idea that farming could support a rapidly growing population is questioned, as hunting and gathering offered more security and flexibility. The textile hypothesis suggests that the demand for woven cloth in response to climate changes tipped the balance in favor of farming.
