“…The BMD-DXA from the specific region of the femur neck (BMD = 0.78, 0.96 and 0.54 g/cm 2 for S1, S2 and S3, respectively) were retrieved and the ROI used to calculate it was individuated. Femur neck ROI was chosen as it represents one of the regions more affected by fragility fractures due to osteoporosis [ 35 ] and one of the most commonly occurring due to sideways fall. The angle between the long bone axis and the femur head was individuated and the stack of images were oriented to obtain the ROI of the femur neck perpendicular to the y -axis (see Figure 4 ).…”

Trabecular bone could be assessed non-invasively using MRI. However, MRI does not yet provide resolutions lower than trabecular thickness and a comparative analysis between different MRI sequences at different field strengths and X-ray microtomography (μCT) is still missing. In this study, we compared bone microstructure parameters and bone mineral density (BMD) computed using various MRI approaches, i.e., turbo spin echo (TSE) and gradient recalled echo (GRE) images used at different magnetic fields, i.e., 7T and 3T. The corresponding parameters computed from μCT images and BMD derived from dual-energy X-ray absorptiometry (DXA) were used as the ground truth. The correlation between morphological parameters, BMD and fracture load assessed by mechanical compression tests was evaluated. Histomorphometric parameters showed a good agreement between 7T TSE and μCT, with 8% error for trabecular thickness with no significative statistical difference and a good intraclass correlation coefficient (ICC > 0.5) for all the extrapolated parameters. No correlation was found between DXA-BMD and all morphological parameters, except for trabecular interconnectivity (R2 > 0.69). Good correlation (p-value < 0.05) was found between failure load and trabecular interconnectivity (R2 > 0.79). These results suggest that MRI could be of interest for bone microstructure assessment. Moreover, the combination of morphological parameters and BMD could provide a more comprehensive view of bone quality.

“…A hip fracture (HF), which refers to a break in the continuity of the femur at the site of its articulation with the pelvis [ 1 ], is a serious clinical event associated with high morbidity and mortality rates in older adults [ 2 ]. HF commonly occurs in individuals aged 80 years [ 3 ]. The incidence of HF has nearly doubled in the past decade in South Korea, and the mortality rate within one year from fracture diagnosis has increased to 20% [ 4 ].…”

Development and validation of a self-care scale for older adults undergoing hip fracture surgery: the HFS-SC

Background The ability to take care of oneself after hip fracture surgery is important for older adults. Various scales have been developed for evaluation of this ability, but a scale specifically focusing on hip fracture has not been developed. The aim of this study was to develop and validate a scale (Hip Fracture Surgery Self-Care Scale, HFS-SC) to evaluate self-care for older adults undergoing hip fracture surgery. Methods The scale was developed according to the guidelines by DeVellis. Initial items were derived from a literature review and individual interviews with 11 older adults who underwent hip fracture surgery. To confirm the suitability of the questions, a preliminary survey was conducted on 25 older adults. Psychometric testing was performed on 300 older adults 65 years old or over living at home after surgery for hip fracture. Psychometric properties of the scale were examined by content validity, construct validity, concurrent validity, internal consistency reliability, and test-retest reliability. Results Exploratory factor analysis and confirmatory factor analysis demonstrated that the 18-item scale comprised five factors (functional independence, symptom recognition and management, positive mental health, participation and support in social activities, and a safe environment). The results of EFA showed that the factor loadings ranging from 0.51 to 0.87. The results of CFA were χ2=375.83, χ2/df=2.14, RMSEA 0.07, SRMR 0.05, GFI 0.88, TLI 0.91, and CFI 0.92 for the 18-item scale. The reliabilities of the scale were 0.91 for Cronbach’s alpha and 0.82 for test-retest reliability. Conclusions The HFS-SC has acceptable validity and reliability and is expected to be useful for evaluating the levels of self-care for older adults undergoing hip fracture surgery and adjusting at the post-fracture period at the community or out-patient department.

“…Hip fractures, an ongoing major health concern among aging populations may not only severely restrict mobility and independence, but may increase the risk of premature mortality. 19 Often associated with an elevated risk of multi morbidity, possible subsequent hip fractures, pain, enormous medical and social costs, and slow recovery rates in survivors, it is possible a host of lifestyle factors, including associated nutrition intakes play a causative and/or mediating role in this negative cycle of health events found in hip fracture patients as outlined by Fusaro et al, 6 and Mortensen et al, 52 In addition, even if not considered by Fiatarone Singh 53 to be relevant in efforts to address hip fracture recovery, a persistently deficient food intake, and related cardiovascular complications may well impact hip fracture mortality risk 54 as well as bone blood supply. 54 As well, osteoporosis found to often accompany hip fracture injuries may ensue 52,54,55 in the absence of adequate vitamin K1 56 especially in those cases who are already vitamin K compromised.…”

Hip fractures remain highly prevalent oftentimes life-threatening events among older populations, despite years of multiple related preventive endeavors. In an effort to explore options for mitigating hip fracture disability and premature death, this mini-review strove to examine whether: 1) Vitamin K, an important dietary compound is a potentially important hip fracture determinant, and 2) whether more research and consideration of this vitamin is warranted. After exploring relevant data concerning this topic as extracted from three well-established preselected electronic data bases housing English language research or commentary reports published over the last 20 years (2000-2022) it is concluded that more intense and thoughtfully designed research to examine the multiple ways vitamin K may mediate bone health, may help towards reducing the persistent global age-associated hip fracture burden and its immense associated human and social costs.
