Men with AS (ankylosing spondylitis) are at elevated risk for CHD (coronary heart disease) but information on risk factors is sparse. We compared a range of conventional and novel risk factors in men with AS in comparison with healthy controls and, in particular, determined the influence of systemic inflammation. Twenty-seven men with confirmed AS and 19 controls matched for age were recruited. None of the men was taking lipid-lowering therapy. Risk factors inclusive of plasma lipids, IL-6 (interleukin-6), CRP (C-reactive protein), vWF (von Willebrand factor), fibrin D-dimer, ICAM-1 (intercellular cell-adhesion molecule-1) and fibrinogen were measured, and blood pressure and BMI (body mass index) were determined by standard techniques. A high proportion (70%) of men with AS were smokers compared with 37% of controls (P = 0.024). The AS patients also had a higher BMI. In analyses adjusted for BMI and smoking, men with AS had significantly higher IL-6 and CRP (approx. 9- and 6-fold elevated respectively; P < 0.001), fibrinogen (P = 0.013) and vWF (P = 0.008). Total cholesterol and HDL-C (high-density lipoprotein cholesterol) were lower (P < 0.05 and P = 0.073 respectively) in AS and thus the ratio was not different. Pulse pressure was also significantly higher in AS (P = 0.007). Notably, adjustment for IL-6 and CRP levels rendered all case-control risk factor differences, except pulse pressure, non-significant. In accordance with this finding, IL-6 correlated positively (r = 0.74, P < 0.001) with fibrinogen, but negatively (r = -0.46, P = 0.016) with total cholesterol concentration. In conclusion, men with AS have perturbances in several CHD risk factors, which appear to be driven principally by systemic inflammatory mediators. Inflammation-driven atherogenesis potentially contributes to the excess CHD risk in AS.

The complication rates reported in this study compare well with previously published studies. These reported results will hopefully serve to provide a benchmark for units in the UK providing corrective spinal deformity surgery to allow individual units to compare their complication rates against national averages and to provide national complication figures to aid in the consenting process of patients. Use of a spinal deformity registry, such as the British Spine Registry, is required to ensure ongoing service development and optimal healthcare provision.

To support the global restart of elective surgery, data from an international prospective cohort study of 8492 patients (69 countries) was analysed using artificial intelligence (machine learning techniques) to develop a predictive score for mortality in surgical patients with SARS-CoV-2. We found that patient rather than operation factors were the best predictors and used these to create the COVIDsurg Mortality Score (https://covidsurgrisk.app). Our data demonstrates that it is safe to restart a wide range of surgical services for selected patients.

The study by Smith et al. (2010) concluded that clips are associated with 3 times the infection rate compared with subcuticular sutures in orthopaedic surgery (P = .01).For hip surgery, there was a 4-fold increase. We aimed to determine the trends and influences in skin closure and wound care for hip and knee arthroplasty in the northwest region as well as what would change surgeons' current practice. A short online survey was emailed to consultants in the northwest of England enquiring about their current practice in superficial skin closure, what has influenced this, and finally what would change their practice. Returned surveys were then analysed. A total of 45 consultants responded (response rate of 40.2%). In both hip and knee arthroplasty, clips were the most commonly used superficial skin closure material (53% and 63%, respectively). Personal experience was the greatest influence on the choice of closure material in both hip and knees (84% and 93% respectively). A total of 66% of hip and 76% of knee surgeons would change their closure material if there was evidence to support this. Hip and knee arthroplasty surgeons are influenced by their personal experience, and most use clips as their skin closure method. Most would change their practice with evidence of one material over another. We conclude that there is need for a prospective, well-powered, multi-centre randomised control trial to determine the skin closure material that has the lowest return-to-theatre rate in arthroplasty surgery.

Distal humeral periprosthetic fractures below intramedullary nail devices are complex and challenging to treat, in particular due to the osteopenic/porotic nature of bone found in these patients. Fixation is often difficult to satisfactorily achieve around the intramedullary device, whilst minimising soft tissue disruption. Descriptions of such cases in the current literature are very rare. We present the case of a midshaft humeral fracture treated with a locking compression plate that developed a nonunion, in a 60-year old female. This went on to successful union after exchange for an intramedullary humeral nail. Unfortunately, the patient developed a distal 1/5th humeral periprosthetic fracture, which was then successfully addressed with a single-contoured, extra-articular, distal humeral locking compression plate (Synthes) with unicortical locking screws and cerclage cables proximally around the distal nail tip region. An excellent postoperative range of motion was achieved.
