Retrospective analyses have shown that osteoporotic pelvic fractures are associated with decreased mobility and independence and with a one-year mortality ranging from 9.5% to 27%. Prospective therapeutic trials are urgently needed.

Background and purposeAdequate restoration of femoral offset (FO) is critical for successful outcome after hip arthroplasty or fixation of hip fracture. Previous studies have identified that hip rotation influences the projected femoral offset (FOP) on plain anteroposterior (AP) radiographs, but the precise effect of rotation is unknown.Patients and methodsWe developed a novel method of assessing rotation-corrected femoral offset (FORC), tested its clinical application in 222 AP hip radiographs following proximal femoral nailing, and validated it in 25 cases with corresponding computed tomography (CT) scans.ResultsThe mean FORC was 57 (29–93) mm, which differed significantly (p < 0.001) from the mean FOP 49 (22–65) mm and from the mean femoral offset determined by the standard method: 49 (23–66) mm. FORC correlated closely with femoral offset assessed by CT (FOCT); the Spearman correlation coefficient was 0.94 (95% CI: 0.88–0.97). The intraclass correlation coefficient for the assessment of FORC by AP hip radiographs correlating the repeated measurements of 1 observer and of 2 independent blinded observers was 1.0 and 1.0, respectively.InterpretationHip rotation affects the FOP on plain AP radiographs of the hip in a predictable way and should be adequately accounted for.

Background Hip fractures are regarded as a worldwide epidemic and a major public health concern. Changing risk factors, local differences and temporal trends contribute to the particular epidemiology of hip fractures. This overview gives a comprehensive insight into the epidemiology of hip fractures and reviews where German data have contributed to the literature. Methods The review of the epidemiology of hip fractures in Germany is based on a systematic literature search in PubMed. Information about the global epidemiology of hip fractures was provided by a selective literature review focusing on specific aspects of the epidemiology of hip fractures. Results Hip fracture rates vary more than 100-fold between different countries. In most high-income countries, a rise in age-standardized hip fracture rates was observed until the 1980s and 1990s and a decrease thereafter. Such a decrease has not been observed for Germany so far. Many factors, diseases and drugs have been found to be associated with hip fractures and there is some evidence that fracture risk in later life is already programmed during fetal life and early childhood. Of the hip fracture burden 50% occur in people with disability and in need of care. In nursing homes approximately 4 fractures can be expected in 100 women per year. In people with intellectual or developmental disabilities comparable risks of hip fracture occur 10–40 years earlier than in the general population. Incidence of disability, institutionalization and death are frequent consequences of hip fractures. Conclusion The epidemiology of hip fractures is characterized by a high burden of disease, local differences, temporal trends, well-defined high-risk populations and many established risk factors.

This study identified high patient age, distinctive comorbidities, male sex, and high osteoporosis grade as significant risk factors for increased in-hospital mortality in the treatment of trochanteric femoral fractures. Furthermore, high ASA grade and a liberal transfusion regime led to an increased incidence of cardio-respiratory complications. Patient-specific characteristics, especially osteoporosis grade and pre-existing medical conditions, may assist in the identification of high-risk patients and allow a patient-specific geriatric co-management plan.

There was a clear tendency to a better overall result in patients receiving multidisciplinary orthogeriatric treatment using a ward visit model of orthogeriatric comanagement, with lower rates of cardiorespiratory complications and mortality. While special care pathways could reduce the rate of myocardial infarction in hip fracture patients, costs and revenues showed no difference between all care models evaluated. However, patients with hip fracture or periprosthetic fracture represent cohorts at clinical and economic risk as well.

It would be advantageous to pretest at-risk individuals in their environment using a simple self-assessment approach, with the main purpose of identifying potential balance problems. With this approach, cost savings in the healthcare system are possible, combined with a higher health-related quality of life in the geriatric population.
