Background: Clinical management in orthogeriatric units and outcome indicators are similar for extracapsular fragility hip fractures, without discriminating between subtrochanteric and pertrochanteric fractures. Hypothesis: Geriatric patients, 75 years or older, with subtrochanteric fractures have worse clinical and functional outcomes than those with pertrochanteric fractures. Materials and methods: Retrospective observational study of data prospectively collected by the Spanish Hip Fracture Registry including patients 75 years or older, admitted for extracapsular hip fractures from January 2017 to June 2019. Demographic and baseline status, pre-operative, post-operative and 30-day follow-up data were included. Results: A total of 13,939 patients with extracapsular hip fractures were registered: 12,199 (87.5%) pertrochanteric and 1740 (12.5%) subtrochanteric. At admission, patients with subtrochanteric fractures were younger (86.5 ± 5.8 versus 87.1 ± 5.6 years old), had better pre-fracture mobility (3.7 ± 2.7 versus 3.9 ± 2.8) (1-to-10 scale, 1 being independent) and were more likely to be living at home; those with pertrochanteric fractures had worse cognitive function (Pfeiffer 3.3 ± 3.3 versus 3.8 ± 3.5). The subtrochanteric fracture group showed worse post-fracture mobility (7.3 ± 2.7 versus 6.7 ± 2.7) and greater deterioration of mobility (3.7 ± 3.0 versus 2.9 ± 2.7). Among individuals living at home at baseline, those with subtrochanteric fractures were more likely to remain in an assisted facility at 30-day follow-up. In-hospital mortality during acute admission was higher for the subtrochanteric group (5.6% versus 4.5%) (p = 0.028). To our knowledge, this is the first paper highlighting the differences between these two fracture groups in the geriatric population. Conclusions: Subtrochanteric fractures in the older population are a different and worse entity, with greater morbimortality and functional decline than pertrochanteric fractures. Despite being younger and fitter at admission, older patients with subtrochanteric fractures have a higher risk of remaining non-weight bearing and undergoing re-operation and institutionalization. Orthogeriatric units should be aware of this and manage subtrochanteric fractures accordingly. Level of evidence: IV.

Background: Hip fractures are prevalent among older people, often leading to reduced mobility, muscle loss, and bone density decline. Malnutrition exacerbates the prognosis post surgery. This study aimed to evaluate the impact of a 12-week regimen of a high-calorie, high-protein oral supplement with β-hydroxy-β-methylbutyrate (HC-HP-HMB-ONS) on nutritional status, daily activities, and compliance in malnourished or at-risk older patients with hip fractures receiving standard care. Subjects and Methods: A total of 270 subjects ≥75 years of age, residing at home or in nursing homes, malnourished or at risk of malnutrition, and post hip fracture surgery, received HC-HP-HMB-ONS for 12 weeks. Various scales and questionnaires assessed outcomes. Results: During the 12 weeks of follow-up, 82.8% consumed ≥75% of HC-HP-HMB-ONS. By week 12, 62.4% gained or maintained weight (+0.3 kg), 29.2% achieved normal nutritional status (mean MNA score +2.8), and 46.8% improved nutritional status. Biochemical parameters improved significantly. Subjects reported good tolerability (mean score 8.5/10), with 87.1% of healthcare providers concurring. Conclusions: The administration of HC-HP-HMB-ONS markedly enhanced nutritional status and biochemical parameters in older hip-fracture patients, with high compliance and tolerability. Both patients and healthcare professionals expressed satisfaction with HC-HP-HMB-ONS.

Objective: This scoping review aimed to identify predictive factors influencing gait recovery post-hip fracture surgery among adults aged 65 and older. Design: A systematic search of MEDLINE, Embase and CINAHL databases was conducted, focusing on studies assessing predictive factors of gait recovery within one month to one-year post-surgery. Two independent reviewers carried out study selection, quality assessment and data extraction using the Quality in Prognosis Studies Tool to gauge evidence levels. Results: About 10,627 articles were initially identified. After duplicates were removed, 7665 were screened based on title and abstract, then 796 based on full text; 138 articles were finally included. The review identified a total of 77 predictive factors. However, just under half (34) of these were supported by studies with a low risk of bias. Higher-level evidence-supported factors were age, pre-fracture independence in daily activities, cognitive impairment, delirium, orthogeriatric multidisciplinary co-management, specific surgical interventions, allowing weight-bearing, comorbidities, nutritional status, rehabilitation treatments and polypharmacy. Conclusion: The identified factors influencing gait recovery include both non-modifiable factors [such as younger age, pre-fracture independence in activities of daily living, absence of cognitive impairment, fewer comorbidities and lower anaesthetic risk] and modifiable factors, including rehabilitation treatments, organisational factors, absence of delirium, orthogeriatric co-management, surgical factors such as implant type and unrestricted weight-bearing, better nutritional status and strength, and reduced polypharmacy. We believe the latter should be prioritised in managing patients with hip fractures to achieve optimal recovery.
