Background: The Asian Working Group for Sarcopenia (AWGS) introduced the concept of "possible sarcopenia" in 2019. However, the association between possible sarcopenia and hip fracture is not well characterized. Hence, we conducted a study to explore this association in older Chinese adults.
Methods: This was a population-based cohort study based on nationally representative data from the China Health and Retirement Longitudinal Study. Individuals aged ≥60 years with no history of hip fracture at baseline (2011-2012) were included and followed up until September 2018. Possible sarcopenia was defined based on the AWGS 2019 criteria during the study period, and the occurrence of hip fractures was monitored. The association between possible sarcopenia and hip fractures was assessed using Cox proportional hazards regression models.
Results: A total of 4,011 participants were included, of whom 44.8 % had possible sarcopenia. During the 7-year follow-up, 197 individuals experienced hip fractures. Individuals with possible sarcopenia had a significantly higher risk of hip fractures than those without possible sarcopenia (hazard ratio: 2.00, 95 % confidence interval: 1.46-2.75; P < 0.001). The association was consistently observed across various subgroups based on age, sex, and overweight status.
Conclusions: This study identified possible sarcopenia as a significant risk factor for hip fractures in older Chinese adults. These findings underscore the importance of addressing possible sarcopenia as a preventive measure to reduce the incidence of hip fractures.

Introduction: Data regarding the incidence of 12-month postoperative cognitive decline following regional or general anaesthesia in older patients undergoing hip fracture surgery remain observational. Compared with general anaesthesia, we hypothesised that regional anaesthesia would decrease the incidence of 12-month postoperative cognitive decline.
Methods: This is substudy of a multicentre randomised trial of regional anaesthesia with no sedation vs.

: Femoral neck fractures are rare but serious injuries in children and adolescents, often resulting from high-energy trauma and prone to complications like avascular necrosis (AVN) and nonunion. Even rarer is the development of slipped capital femoral epiphysis (SCFE) following femoral neck fracture, which presents unique diagnostic and treatment challenges. SCFE can destabilize the femoral head, with severe cases requiring complex surgical interventions.

The aim of the study was to investigate the differences of the reamed versus the unreamed short proximal femoral nailing (PFN), in terms of the duration of surgery and the outcome. The impact of patients and fracture characteristics to the outcome was also evaluated.

A retrospective study of all orthopaedic cases with a hip fracture from 2020 to 2022 at CHC Montlegia has been undertaken, the group is compared to patients with the same impairment from 2018-2020 admitted to Saint Joseph/Esperance CHC hospitals (before the merge and the existence of a DOTR). The delay between the arrival at the emergency department and transfer to the operating room, as well as the mortality are evaluated.

A double-blind randomized controlled trial was conducted in 140 patients with hip fracture. After randomization, 68 patients received a single dose of 1 gr of intravenous TXA at the start of the surgery (TXA group), and 72 received a placebo treatment (placebo group).
