<b><i>Introduction:</i></b> Numerous studies reported poorer outcomes for patients who were admitted at weekends or off-hour, which relates to the underlying concept called the “weekend effect.” We aimed to assess the effect of adverse outcomes in older patients with intertrochanteric fracture surgery. <b><i>Methods:</i></b> A retrospective cohort study of patients aged ≥65 years with intertrochanteric fracture surgery. Data were collected from computerized medical records and all patients had a long-term follow-up. The association between weekend effect with adverse outcomes and factors for all-cause mortality was studied by 3-group comparison, Spearman and partial correlation analysis, univariate analysis, and multivariate Cox proportional-hazard model. <b><i>Results:</i></b> Our results showed no evidence supporting the existence of a weekend effect on adverse outcomes, including mortality rates (<i>p</i> = 0.950, log-rank), length of hospital stay, total hospital costs, rate and volume of transfusion, visual analog scale score, Harris Hip Score, and specific complications (all <i>p</i> > 0.05), except for an average of 0.5 days longer surgical delay found in patients admitted on Fridays relative to other days (<i>p</i> = 0.013). Instead, only age group (with a 10-year interval, HR 1.43, 1.28–1.59 95% CI, <i>p</i> < 0.001) and surgical delay (HR 1.05, 1.02–1.07 95% CI, <i>p</i> < 0.001) were identified as significantly associated with all-cause mortality. <b><i>Conclusions:</i></b> Older patients with intertrochanteric fracture surgery have similar mortality and adverse outcomes rates when admitted on weekends or holidays compared with weekdays. Our findings suggest that collaborative multidisciplinary team care seems both effective and efficient in the management of older patients with intertrochanteric fractures on any day of the week.
Aims With relatively thinner cortical thickness, the management of acetabulum osteoporotic fractures in elderly patients is difficult. The aim of the research was to compare and present the morphological characteristics of the quadrilateral plate in young and elderly age groups, such as the area, and position distribution of the thin cortical thickness region, fracture lines maps, and propose a revised design plate for elderly patients based on these anatomic information. Methods As a retrospective research, acetabular fracture with one normal hemipelvises, including 110 men and 39 women, were collected to present the morphological characteristics of the quadrilateral region. The subjects were divided into three different age groups: Group I = 18–40 years (31.3 ± 6.6 years), Group II = 41–60 years (49.9 ± 5.3 years), and Group III ≥ 61 years (68.7 ± 6.8 years). The area of the quadrilateral surface, the area and position distribution of the thin cortical thickness region, the ratio and fracture lines maps were calculated and compared with Mimics in different groups. Results The thin cortical thickness/width region area (TCWRA) was significantly increased in Group III compared with Group I and Group II. The ratio of TCWRA accounted for in the quadrilateral region was also significantly increased in Group III (≥ 61 years) compared with Group I (P = 0.01) and Group II (P = 0.011). None of the subjects had a component involving the “A” zone, thirty-three thin cortical thickness regions were located in the “B” zone, and one hundred and sixteen involved both zones of the quadrilateral plate (“A + B” zone). Furthermore, there were a significant differences in the fracture line distributions in three age groups. More fracture lines of elderly patients were located at anterior part (B zone) compared with Group I and Group II. Conclusions It was identified the area of thin cortical thickness region increased as age grown, and fracture lines were inclined to be more distributed in “B” zone in elderly patients. To meet the demands of acetabular fixation in different age groups, cortical thickness changes in young and elderly individuals should be given special attention when the quadrilateral surface plate is designed. Level of evidence Level IV, observational study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
