Aims This study aims to define the epidemiology of trauma presenting to a single centre providing all orthopaedic trauma care for a population of ∼ 900,000 over the first 40 days of the COVID-19 pandemic compared to that presenting over the same period one year earlier. The secondary aim was to compare this with population mobility data obtained from Google. Methods A cross-sectional study of consecutive adult (> 13 years) patients with musculoskeletal trauma referred as either in-patients or out-patients over a 40-day period beginning on 5 March 2020, the date of the first reported UK COVID-19 death, was performed. This time period encompassed social distancing measures. This group was compared to a group of patients referred over the same calendar period in 2019 and to publicly available mobility data from Google. Results Orthopaedic trauma referrals reduced by 42% (1,056 compared to 1,820) during the study period, and by 58% (405 compared to 967) following national lockdown. Outpatient referrals reduced by 44%, and inpatient referrals by 36%, and the number of surgeries performed by 36%. The regional incidence of traumatic injury fell from 5.07 (95% confidence interval (CI) 4.79 to 5.35) to 2.94 (95% CI 2.52 to 3.32) per 100,000 population per day. Significant reductions were seen in injuries related to sports and alcohol consumption. No admissions occurred relating to major trauma (Injury Severity Score > 16) or violence against the person. Changes in population mobility and trauma volume from baseline correlated significantly (Pearson’s correlation 0.749, 95% CI 0.58 to 0.85, p < 0.001). However, admissions related to fragility fractures remained unchanged compared to the 2019 baseline. Conclusion The profound changes in social behaviour and mobility during the early stages of the COVID-19 pandemic have directly correlated with a significant decrease in orthopaedic trauma referrals, but fragility fractures remained unaffected and provision for these patients should be maintained.

This study found that gentamicin and daptomycin were the only effective single-agent antibiotics against established Staphylococcus biofilms. Interestingly the addition of a bacteriostatic antibiotic was found to antagonize the ability of gentamicin to eradicate Staphylococcus biofilms.
These results suggest that the previously documented clinical benefits of the fibular nail are complemented by biomechanical properties that compare favorably to standard techniques.

Aims Currently, periprosthetic fractures are excluded from the American Society for Bone and Mineral Research (ASBMR) definition of atypical femoral fracture (AFFs). This study aims to report on a series of periprosthetic femoral fractures (PFFs) that otherwise meet the criteria for AFFs. Secondary aims were to identify predictors of periprosthetic atypical femoral fractures (PAFFs) and quantify the complications of treatment. Patients and Methods This was a retrospective case control study of consecutive patients with periprosthetic femoral fractures between 2007 and 2017. Two observers identified 16 PAFF cases (mean age 73.9 years (44 to 88), 14 female patients) and 17 typical periprosthetic fractures in patients on bisphosphonate therapy as controls (mean age 80.7 years (60 to 86, 13 female patients). Univariate and multivariate analysis was performed to identify predictors of PAFF. Management and complications were recorded. Results Interobserver agreement for the PAFF classification was excellent (kappa = 0.944; p < 0.001). On univariate analysis compared with controls, patients with PAFFs had higher mean body mass indices (28.6 kg/m2 (sd 8.9) vs 21.5 kg/m2 (sd 3.3); p = 0.009), longer durations of bisphosphonate therapy (median 5.5 years (IQR 3.2 to 10.6) vs 2.4 years (IQR 1.0 to 6.4); p = 0.04), and were less likely to be on alendronate (50% vs 94%; p = 0.02) with an indication of secondary osteoporosis (19% vs 0%; p = 0.049). Duration of bisphosphonate therapy was an independent predictor of PAFF on multivariate analysis (R2 = 0.733; p = 0.05). Following primary fracture management, complication rates were higher in PAFFs (9/16, 56%) than controls (5/17, 29%; p = 0.178) with a relative risk of any complication following PAFF of 1.71 (95% confidence interval (CI) 0.77 to 3.8) and of reoperation 2.56 (95% CI 1.3 to 5.2). Conclusion AFFs do occur in association with prostheses. Longer duration of bisphosphonate therapy is an independent predictor of PAFF. Complication rates are higher following PAFFs compared with typical PFFs, particularly of reoperation and infection. Cite this article: Bone Joint J 2019;101-B:1285–1291
Our results suggest that in clinical practice, extrinsic factors such as preparation conditions and methods probably play a more important role than the intrinsic variability of cements. However, variability in handling and viscosity will exist in all brands of cement prepared under theater conditions and the surgeon must be aware of why they may act differently.
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.
