“…Franken et al [ 20 ] also found that impingement-associated deformities of the hip may cause FNSF. Tokyay et al [ 21 ] pointed out that acetabular morphology can predict the types of proximal femoral fractures among elderly patients. NSA of trochanteric fracture was found to be less than that of the femoral neck fracture, but there was no statistically significant difference between them.…”

β cells are the main cells responsible for the hypoglycemic function of pancreatic islets, and the insulin secreted by these cells is the only hormone that lowers blood glucose levels in the human body. β cells are regulated by various factors, among which neurotransmitters make an important contribution. This paper discusses the effects of neurotransmitters secreted by various sympathetic and parasympathetic nerves on β cells and summarizes the mechanisms by which various neurotransmitters regulate insulin secretion. Many neurotransmitters do not have a single source and are not only released from nerve terminals but also synthesized by β cells themselves, allowing them to synergistically regulate insulin secretion. Almost all of these neurotransmitters depend on the presence of glucose to function, and their actions are mostly related to the Ca2+ and cAMP concentrations. Although neurotransmitters have been extensively studied, many of their mechanisms remain unclear and require further exploration by researchers.

“…Several studies comparing osteoporotic hip fractures regarding bone quality, age and morphology have been performed previously. Most of them assessed the proximal morphology as an important factor for determining the fracture type [9,18,19]. Cory et al investigated the fracture morphology of high shear angle vertical neck fractures in young adult patients under age of fifty years and vertical coronal fractured averaged 60 degrees and axial fracture obliquity averaged 24 degrees with deficiency in the posterior neck.…”

Objective: Femoral neck fractures mostly occurs due to high-energy trauma in young population and management differs compared to elderly. Different geometric parameters in the hip joint can play a role in fracture morphology regarding to the age. Present study aims to compare hip morphology between young and elderly population Materials and methods: 45 patients with isolated femoral neck fracture included to the study. Patients were divided into two regarding to the age; group 1 (younger than 60 yr.) and group 2 (older than 60 yr.). Garden and Pauwels classifications, Sharp angle (acetabular index-AI), acetabular depth (AD), Hip-axis length (HLA), Neck-shaft angle (NSA), Center-edge angle (CE), Singh indexes and femur head extrusion indexes were compared between groups. Results: The mean age of group 1 (22 patients) was 48 ± 10.4 while the mean age of group 2 (23 patients) was 77 ± 6.3. Significant differences found in 3 parameters; the mean HLA (13.4 ± 1.4 cm vs 12 ± 1.1 cm) (p: 0,034), the Sharp angle (37.9° ± 5° vs 40.3° ± 3°) (p: 0.047) and the CE (38.1° ± 6.2° vs 34.8° ± 4.5°) (p: 0.48) between group 1 and 2 respectively. No statistically significant difference was found in terms of AD, NSA, Singh index and extrusion index. Conclusions: Our study shows influence of proximal femoral and acetabular morphology on femoral neck fracture in young patients and may help future studies to reveal the relevance between hip morphology and fractures type.

Purpose This study aimed to evaluate the intrinsic risk factors for SFFFH in young military recruits. Methods We retrospectively analyzed 98 SFFFH and 24 ONFH patients who were affiliated with the Chinese People's Liberation Army (PLA) between 2013 and 2019. X-ray and MRI were the main data for analysis. Acetabular anteversion of the superior acetabulum (AVsup), acetabular anteversion of the center of the acetabulum (AVcen), anterior acetabular sector angle (AASA), posterior acetabular sector angle (PASA), superior acetabular sector angle (SASA), neck-shaft angle (NSA), inferior iliac angle (IIA) and ischiopubic angle (IPA) were calculated by two observers with three times. Then, logistics regression and independent samples T-test were performed to analyze the above data to explore the risk factors of SFFFH. Results Based on the results of logistics regression, age (OR: 1.33; 95% CI: 1.12-1.65; P-value = 0.0031) could be considered as the indicator. AVcen (P-value = 0.0334), AASA (P-value = 0.0002), NSA (P-value = 0.0007), IIA (P-value = 0.0316) were considered to be statistical significance. Further, AVcen (OR: 1.41; 95% CI: 1.04-1.95) and AASA (OR: 1.44; 95% CI: 1.21-1.77) especially AASA (area under curve: 66.6%) should be paid much more attention. Conclusions We unveiled that AASA could be the key factor for SFFFH, which further verified that deficient anterior coverage of the acetabulum might be the main cause of SFFFH.

The Influence of Acetabular Morphology on Prediction of Proximal Femur Fractures Types in an Elderly Population

Abstract: The rate of trochanteric femur fractures is higher in patients with high acetabular index, whereas the rate of femoral neck fractures is higher in patients with increased hip axis length.
