Impact of COVID-19 on clinical outcomes for patients with fractured hip
AIMS:
There are reports of a marked increase in perioperative mortality in patients admitted to hospital with a fractured hip during the COVID-19 pandemic in the UK, USA, Spain, and Italy. Our study aims to describe the risk of mortality among patients with a fractured neck of femur in England during the early stages of the COVID-19 pandemic.
Methods:
We completed a multicentre cohort study across ten hospitals in England. Data were collected from 1 March 2020 to 6 April 2020, during which period the World Health Organization (WHO) declared COVID-19 to be a pandemic. Patients ≥ 60 years of age admitted with hip fracture and a minimum follow-up of 30 days were included for analysis. Primary outcome of interest was mortality at 30 days post-surgery or postadmission in nonoperative patients. Secondary outcomes included length of hospital stay and discharge destination.
Results:
In total, 404 patients were included for final analysis with a COVID-19 diagnosis being made in 114 (28.2%) patients. Overall, 30-day mortality stood at 14.4% (n = 58). The COVID-19 cohort experienced a mortality rate of 32.5% (37/114) compared to 7.2% (21/290) in the non-COVID cohort (p < 0.001). In adjusted analysis, 30-day mortality was greatest in patients who were confirmed to have COVID-19 (odds ratio (OR) 5.64, 95% confidence interval (CI) 2.95 to 10.80; p < 0.001) with an adjusted excess risk of 20%, male sex (OR 2.69, 95% CI 1.37 to 5.29; p = 0.004) and in patients with ≥ two comorbidities (OR 4.68, CI 1.5 to 14.61; p = 0.008). Length of stay was also extended in the COVID-19 cohort, on average spending 17.6 days as an inpatient versus 12.04 days in the non-COVID-19 group (p < 0.001).
Conclusion:
This study demonstrates that patients who sustain a neck of femur fracture in combination with COVID-19 diagnosis have a significantly higher risk of mortality than would be normally expected

Radiological outcomes following surgical fixation with wires versus moulded cast for patients with a dorsally displaced fracture of the distal radius: a radiographic analysis from the DRAFFT2 trial.
AIMS: The primary aim of this study was to report the radiological outcomes of patients with a dorsally displaced distal radius fracture who were randomized to a moulded cast or surgical fixation with wires following manipulation and closed reduction of their fracture. The secondary aim was to correlate radiological outcomes with patient-reported outcome measures (PROMs) in the year following injury. METHODS: Participants were recruited as part of DRAFFT2, a UK multicentre clinical trial. Participants were aged 16 years or over with a dorsally displaced distal radius fracture, and were eligible for the trial if they needed a manipulation of their fracture, as recommended by their treating surgeon. Participants were randomly allocated on a 1:1 ratio to moulded cast or Kirschner wires after manipulation of the fracture in the operating theatre. Standard posteroanterior and lateral radiographs were performed in the radiology department of participating centres at the time of the patient's initial assessment in the emergency department and six weeks postoperatively. Intraoperative fluoroscopic images taken at the time of fracture reduction were also assessed. RESULTS: Patients treated with surgical fixation with wires had less dorsal angulation of the radius versus those treated in a moulded cast at six weeks after manipulation of the fracture; the mean difference of -4.13° was statistically significant (95% confidence interval 5.82 to -2.45). There was no evidence of a difference in radial shortening. However, there was no correlation between these radiological measurements and PROMs at any timepoint in the 12 months post-injury. CONCLUSION: For patients with a dorsally displaced distal radius fracture treated with a closed manipulation, surgical fixation with wires leads to less dorsal angulation on radiographs at six weeks compared with patients treated in a moulded plaster cast alone. However, the difference in dorsal angulation was small and did not correlate with patient-reported pain and function
The assessment of rat ureteral pressure generation in vitro: regional heterogeneity and influence of distending pressure
Contraction of ureteral smooth muscle drives the urine bolus to the urinary bladder for storage prior to micturition. This study describes a novel approach to the measurement of ureteral pressure generation
in vitro
and the influence of distending pressure on acetylcholine-stimulated ureteral lumenal pressure generation.Isolated segments of ureters obtained from Wistar rats were pressurised in a blind-ended sac arrangement and contractile responses were recorded as phasic oscillations in ureteral luminal pressure. Distal segments generated greater luminal pressures than proximal segments (p<0.001) in response to acetylcholine. Increasing baseline distending pressures in the range 2–10 mmHg in proximal segments was associated with greater frequency of contraction (p<0.001) and decreased magnitude of contraction (p<0.001) when expressed as % maximum response. Nifedipine (10-5M) or removal of extracellular Ca2+
abolished the contractions. Isometric contractile responses of ureteral ring preparations were not significantly influenced by pretensions equivalent to distending pressures in the range 2–10 mmHg.This is the first study to fully establish the influence of baseline ureteral distending pressure upon ureteral luminal pressure generation
in vitro
and demonstrates regional heterogeneity of ureteral contractile responses. It is suggested that this experimental approach may be a useful methodology for the investigation of ureteral function during urinary outflow obstruction
ARthroscopy in Knee OsteoArthritis (ARK-OA): a multicentre study assessing compliance to national guidelines.
INTRODUCTION: The use of arthroscopy to alleviate the symptoms of osteoarthritis has been questioned by recent high quality evidence. This has led to the development of guidelines by specialist and national bodies advocating against its use. AIMS: To examine the trends of the rates of arthroscopy in patients with knee osteoarthritis over the past five years and determining compliance with guidelines. METHODS: Multi-centre, retrospective audit in five hospital trusts in the United Kingdom. The number of arthroscopies performed by month from 2013 to 2017 was identified through hospital coding. Fifty randomly selected records from the year 2017 were further analysed to assess compliance with NICE guidelines. RESULTS: Between 2013 and 2017, the number of arthroscopies performed annually in five trusts dropped from 2028 to 1099. In the year 2017, 17.7% of patients with no mechanical symptoms and moderate-to-severe arthritis pre-operatively had arthroscopy. CONCLUSION: Knee arthroscopy continues to be used as a treatment for osteoarthritis, against national guidelines. Whilst overall numbers are declining, further interventions, including implementation of high-quality conservative care is required to further eliminate unnecessary procedures
