Background: hip fractures result in a significant burden to the patient, their caregivers and the health care system. Patients with Alzheimer's disease (AD) have a higher incidence of hip fracture compared with other older people without AD, although it is not clear if AD is an independent risk factor for hip fracture.
Methods: a retrospective cohort study was conducted using anonymised electronic medical records from primary care practices in the United Kingdom. Proportional hazards regression modelling with adjustment for potential confounders was used to evaluate AD as an independent risk factor for predicting hip fractures.
Results: the incidence of hip fracture among patients with and without AD was 17.4 (95% CI, 15.7-19.2) and 6.6 (95% CI, 5.8-7.6) per 1,000 person years, respectively. Patients with AD had a hazard that was 3.2 (95% CI, 2.4-4.2) times that of non-AD patients after controlling for potential confounders. AD patients who experienced a hip fracture also had an increased mortality rate compared with non-AD patients who experienced a hip fracture (hazard ratio = 1.5; 95% CI, 1.1-1.9).
Conclusion: patients with AD and their caregivers should be advised on how to prevent hip fractures and more attention should be given to AD patients who are undergoing rehabilitation following a hip fracture.

Fracture surgeries are frequently accompanied by severe pain, necessitating efficacious pain management strategies to enhance postoperative recovery. Nerve block techniques, which are critical in mitigating pain, involve the targeted administration of local anesthetics to disrupt nerve signal transmission, thereby achieving significant analgesia. Traditionally, these techniques rely on anatomical landmarks and the clinician's expertise, which can introduce variability and potential risks.

Rationale & Objective: There are likely over 42 million patients with hypertension taking thiazides in the United States and many more worldwide. Hyponatremia is a common complication of thiazide therapy. It is not currently known if thiazide-associated hyponatremia is also associated with increased mortality.

Background: A population-based study delineating the epidemiologic, clinical, and treatment characteristics of femoral neck fractures (FNFs) in elderly patients has not yet been conducted in Turkey. In this nationwide study, the epidemiologic, clinical, and treatment characteristics of patients aged ⩾65 years with FNFs who underwent osteosynthesis, hemiarthroplasty (HA), or total hip arthroplasty (THA) were examined.
Methods: Patients aged ⩾65 years with FNFs were identified in this retrospective, nationwide study.

Department of Trauma and Orthopeadics, Peking University People's Hospital, Beijing, People's Republic of China.
Objective: Reverse obliquity intertrochanteric fracture is an unstable type of fracture. Current guidelines recommend intramedullary fixation, but there are still complications such as screw removal, hip varus, nail withdrawal, and nail fracture. The objective of this study was to use finite element analysis to compare the biomechanical properties of the novel proximal femoral bionic nail (PFBN), proximal femoral nail antirotation (PFNA), and combined compression interlocking intramedullary nail (InterTan) in the treatment of reverse obliquity intertrochanteric fractures (AO/OTA 31-A3.

Background: Simultaneous cardiac and non-cardiac surgeries can be beneficial for patients, but there are still few reports on this approach.
Case Presentation: A 90-year-old woman was diagnosed with a femoral trochanteric fracture and severe aortic stenosis. A heart team conference decided to perform transcatheter aortic valve implantation (TAVI) and femoral osteosynthesis under general anesthesia on the same day.
