- Background Reduced bone mineral density (BMD) together with muscle wasting and dysfunction, that is sarcopenia, emerges as a risk factor for hip fracture. The aim of this study was to examine body composition and BMD and their relationship with trauma mechanisms in young and middle-aged patients with femoral neck fracture. Materials and methods Altogether, 185 patients with femoral neck fracture aged 20-69 were included. BMD, body composition and fat-free mass index (FFMI) were determined by dual-X-ray absorptiometry (DXA), and trauma mechanisms were registered. Results Ninety per cent of the whole study population had a femoral neck BMD below the mean for age. In the young patients (<50years), 27% had a Z-score of BMD-2 SD. More than half of the middle-aged patients (50-69years) had osteopenia, that is T-score -1 to -25, and 35% had osteoporosis, that is T-score<-25, at the femoral neck. Patients with low-energy trauma, sport injury or high-energy trauma had a median standardised BMD of 0702, 0740 vs. 0803g/cm(2) (P=003), and a median FFMI of 159, 177 vs. 175kg/m(2) (P<0001), respectively. FFMI<10th percentile of an age- and gender-matched reference population was observed in one-third. Conclusions A majority had low BMD at the femoral neck, and one-third had reduced FFMI (i.e. sarcopenia). Patients with fracture following low-energy trauma had significantly lower femoral neck BMD and FFMI than patients with other trauma mechanisms. DXA examination of both BMD and body composition could be of value especially in those with low-energy trauma.

- Background and purpose: A femoral neck fracture (FNF) may have long-term effects on the patient's func-tion, also in patients younger than 70 years. These long-term effects are not well described, since most studies have short follow-ups. The aim of this study was to investigate clinical outcome by performance -based functional tests, hand grip strength, and hip function in different subgroups. The secondary aim was to study surgical complications, bone mineral density (BMD) and occurrence of sarcopenia 10 years after a FNF. Patients and methods: A prospective multicenter study with a 10-year follow-up of patients aged 20- 69 years with a FNF treated with internal fixation (IF). Five-times sit-to-stand test (5TSST), 4-m walking speed test, hand grip strength (HGS) and Harris Hip Score (HHS) were performed.A radiographic examination of the hip was performed and re-operations were registered. Bone min-eral density (BMD) at the hip, spine and total body composition were assessed with dual energy x-ray absorptiometry (DXA). Present sarcopenia was determined by the combination of reduced functional per-formance and low fat-free mass index (FFMI).Results: A total of 58 patients were included. 5TSTS was normal in 45% of the patients and old age was associated with poorer performance ( p < 0.001). 76% of the study population had a normal speed gait and likewise, old age ( p = 0.005) and walking aids ( p = 0.001) were associated with poor performance. HGS was normal in 82% of the men and 64% of the women. HHS showed that 85% had a good/excellent function. A major re-operation was performed in 34% of the patients with displaced FNF and in 20% of patients with non-displaced FNF. 74% displayed osteopenia and 12% osteoporosis. 17% of the men and 38% of the women had sarcopenia.Interpretation: The majority of patients less than 70 years of age with a FNF treated with IF, had normal functional tests, muscle strength and a good hip function ten years post-operatively. However, one in ten had osteoporosis, and one third was sarcopenic which indicate the importance of encouraging regular muscle preserving resistance training after hip fracture.(c) 2022 The Authors.

- Objectives: To evaluate potential sex differences and other factors associated with complications within 4 months after a hip fracture. Methods: A total of 1,915 patients. 65 years (480 men) with hip fracture were consecutively included in a prospective multicenter cohort study. A review of medical records and patient interviews according to a study protocol based on the Standardized Audit of Hip Fractures in Europe (SAHFE, RIKSHOFT) was performed. Sex differences in comorbidity according to the American Society of Anesthesiologists score and complications 4 months after a hip fracture were registered. Multivariate logistic regression analysis was performed to identify factors related to complications. Results: Male sex was associated with worse general health according to the American Society of Anesthesiologists classification (P=0.005) and with more comorbidities (P<0.001). Male sex emerged as a risk factor for developing pneumonia (P<0.001), and additionally, 18% of the men suffered from cardiac complications compared with 13% of the females (P=0.018). Female sex was predisposed for urinary tract infections, 30% vs 23% in males (P=0.001). Mortality was higher in the male vs female group, both within 30 days (15% vs 10%, P=0.001) and at 4 months (24% vs 14%, P=0.001). Conditions associated with pneumonia were male sex, pulmonary disease, and cognitive impairment. Cardiac complications were associated with delayed surgery and cardiovascular and pulmonary disease. Conclusion: Before surgery, men with hip fracture already have a poorer health status and higher comorbidity rate than women, thus resulting in a twofold increased risk of pneumonia. Cognitive dysfunction and pulmonary disease contributed to pneumonia in men. Delayed surgery seems to increase the risk for cardiac complications. It is important to consider the sex perspective early on together with cardiopulmonary comorbidity and cognitive dysfunction to be able to counteract serious complications that may lead to death.

- Background: The catabolic state that follows hip fracture contributes to loss of muscle mass and strength, that is sarcopenia, which impacts functional ability and health-related quality of life. Measures to prevent such long-term postoperative consequences are of important concern. The aim of this study was to evaluate the combined effects of protein-rich nutritional supplementation and bisphosphonate on body composition, handgrip strength and health-related quality of life following hip fracture. Methods: The study included 79 men and women with hip fracture, mean age 79 years (SD 9), without severe cognitive impairment, who were ambulatory and living independently before fracture. Patients were randomized postoperatively to receive liquid supplementation that provided 40 g of protein and 600 kcal daily for six months after the fracture, in addition to bisphosphonates once weekly for 12 months (group N, n = 26), or bisphosphonates alone once weekly for 12 months (group B, n = 28). All patients, including the controls (group C, n = 25) received calcium 1 g and vitamin D3 800 IU daily. Body composition as measured by dual-energy X-ray absorptiometry (DXA), handgrip strength (HGS) and health-related quality of life (HRQoL) were registered at baseline, six and 12 months postoperatively. Results: There were no differences among the groups regarding change in fat-free mass index (FFMI), HGS, or HRQoL during the study year. Intra-group analyses showed improvement of HGS between baseline and six months in the N group (P = 0.04). HRQoL decreased during the first year in the C and B groups (P = 0.03 and P = 0.01, respectively) but not in the nutritional supplementation N group (P = 0.22). Conclusions: Protein-rich nutritional supplementation was unable to preserve FFMI more effectively than vitamin D and calcium alone, or combined with bisphosphonate, in this relatively healthy group of hip fracture patients. However, trends toward positive effects on both HGS and HRQoL were observed following nutritional supplementation.
