Dementia and hip fractures are 2 conditions that are seen primarily in older adults, and both are associated with substantial morbidity and mortality. An individual with dementia is up to 3 times more likely than a cognitively intact older adult to sustain a hip fracture. This may occur via several mechanisms, including (1) risk factors that are common to both outcomes; (2) the presence of dementia increasing hip fracture incidence via intermediate risk factors, such as falls, osteoporosis, and vitamin D; and (3) treatment of dementia causing side effects that increase hip fracture risk. We describe a model that applies these 3 mechanisms to explain the relationship between dementia and hip fractures. Comprehensive understanding of these pathways and their relative influence on the outcome of hip fracture will guide the development of effective interventions and potentially improve prevention efforts.

Cephalomedullary nail is the gold standard treatment for intertrochanteric fracture in geriatric population. 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).

The aim of this paper is to identify if there is a difference in length of stay following hip fractures when using rehabilitation beds. Prospective data was collected on all hip fracture admissions in patients over 50 years from May 2016 to February 2018 from ISD NHS Scotland to identify length of stay. It was found that patients discharged home via rehabilitation wards were less likely to have returned to their own home by 30 days post admission and were also significantly more likely to stay in hospital for 40 days or more when compared to patients discharged directly home.
