Objective: This study aims to investigate the incidence and clinical significance of sodium, potassium and calcium electrolyte disturbances in elderly patients with hip fracture before an operation.
Methods: The clinical data of 220 patients with intertrochanteric fracture and 261 patients with femoral neck fracture from September 2013 to December 2016 in our hospital (≥60 years old) was reviewed. The sodium, potassium and calcium values, and the underlying diseases of patients were recorded after the first blood test. These patients were divided into two groups according to the fracture site: femoral neck fracture group and intertrochanteric fracture group. Then, the differences between these two groups were compared to analyze the proportion of electrolyte disturbances in elderly patients with hip fracture, and explore its clinical significance.
Results: Patients with intertrochanteric fractures were older than patients with femoral neck fracture. There was no significant difference in the prevalence of underlying diseases between these two groups. The incidence of hyponatremia, hypokalemia and hypocalcemia was 10.0%, 32.9% and 1.4%, respectively, in the femoral neck fracture group, and 24.3%, 21.1% and 7.7%, respectively, in the intertrochanteric fracture group. The incidence of hypernatremia, hyperkalemia and hypercalcemia was 1.4%, 1.4% and 0.9%, respectively, in the femoral neck fracture group, and 1.1%, 0.7% and 0.8%, respectively, in the intertrochanteric fracture group.
Conclusion: Patients with old hip fractures before an operation are prone to hyponatremia, hypokalemia and hypocalcemia, and most of them have mild electrolyte disorders, which needs to be corrected in time. Furthermore, some patients urgently need urgent supplementation ofblood electrolytes for some diseases, the correction of electrolyte disorders, and the prevention of serious adverse consequences.
Key Words: Femoral neck fracture, Femoral intertrochanteric fracture, Hyponatremia, Hypokalemia, Hypocalcemia.

Purpose: Hip fractures in elderly individuals are associated with high mortality rates, even with advanced treatment options. Identifying factors correlated with mortality could guide potential preventive strategies. Elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels, as well as the AST/ALT ratio (AAR), have been associated with mortality in various diseases, but their association with hip fracture mortality remains underexplored.

Background: Reduced Bone Mineral Density (BMD) has been linked to Human Immunodeficiency Virus (HIV) infection and treatment. There is a lack of information regarding the osteoporosis status of middle-aged patients with HIV in Iran, despite the fact that Antiretroviral Therapy (ART) is widely accessible.
Objective: The purpose of this cross-sectional study was to assess the BMD status and low BMD risk factors in patients with HIV under ART living in Iran.

Objective: Despite several surgical options, there has yet to be a consensus on the best treatment for femoral neck fracture (FNF) due to higher complication rates compared to other bone fractures. This study aims to examine the possible consequences and solution suggestions of changing screws during surgery for various reasons in FNF surgical treatment from a biomechanical perspective.
Method: FNF and treatment materials were analyzed biomechanically using a package program based on the finite element method (FEM).

Background: Hypotension during anesthesia for surgery for hip fracture is common and associated with myocardial injury, stroke, acute kidney injury, and delirium. We hypothesized that maintaining intraoperative blood pressure close to patients' preoperative values would reduce these complications compared to usual care.
Methods: A pilot feasibility patient- and assessor-blinded parallel group randomized controlled trial.
