Background: Surgical mortality data are collected routinely in high-income countries, yet virtually no low-or middle-income countries have outcome surveillance in place. The aim was prospectively to collect worldwide mortality data following emergency abdominal surgery, comparing findings across countries with a low, middle or high Human Development Index (HDI).Methods: This was a prospective, multicentre, cohort study. Self-selected hospitals performing emergency surgery submitted prespecified data for consecutive patients from at least one 2-week interval during July to December 2014. Postoperative mortality was analysed by hierarchical multivariable logistic regression.
Introduction There has been guidance from the government and orthopaedic community on how best to ensure the safety of our patients and colleagues as we recommence elective surgery in the UK. The primary aim was to determine what proportion of patients feel they should proceed with their elective hip and knee arthroplasty surgery during the COVID-19 climate. The secondary aim was to investigate what variables affected this decision. Methods Patient information from a single surgeon's waiting list in a district general hospital were recorded. A standardised telephone discussion was had with all the patients noting the severity of pain and the potential reasons for not wanting to proceed with surgery. Results A total of 70.6% (96/136) of patients wished to proceed with surgery; 29.4% (40/136) did not wish to proceed. The decision to proceed with surgery was not correlated with sex, American Society of Anesthesiologists grade or COVID-19 risk. Those who wished to proceed with surgery had a mean age of 68.5 years while those who did not had a mean age of 72.4 years (P = 0.03). Within the matched subgroups, patients under the age of 70 years were more willing to proceed with primary hip arthroplasty surgery (87.9%) compared with primary knee arthroplasty surgery (57.1%; P = 0.007); 75% of the patients who did not wish to proceed with surgery expressed concerns about perioperative COVID-19 infection. Conclusion There is a significant proportion of arthroplasty patients on waiting lists who would be willing to accept the increased risks associated with COVID-19 to undergo surgery on an urgent basis. The subgroup of younger patients awaiting hip arthroplasty is more willing than those awaiting knee arthroplasty to proceed with surgery.
Objective: The purpose of our study was to determine whether there is a correlation between the lower limb rotational profile and tibial tuberosity-trochlea groove (TT-TG) distance. Design and patients: The computed tomography cross-sectional imaging on 50 patients’ lower limbs (100 limbs) was investigated at our institution. The TT-TG distance was measured along with rotational measurements including femoral version (FV), tibial torsion and knee joint rotation angle (KJRA). Patients were divided into two groups. Group 1 had a TT-TG ≥ 20 mm which was considered pathological and group 2 with a non-pathological TT-TG (≤19 mm). Rotational angles were compared between groups. Statistical analysis was performed using the t-test and Mann–Whitney U analysis. Results and conclusions: Our results demonstrated a statistically significant difference in the mean KJRA ( p = 0.026) between the pathological (mean = 10.6, standard deviation (SD) = 7.79°) and the non-pathological TT-TG groups (mean = 6.99, SD = 5.06°). A higher mean value for FV and tibial torsion was also demonstrated in patients with a pathological TT-TG (18.2 vs. 13.7, 32.8 vs. 30.9, p > 0.05, respectively). In conclusion, there was a statistically significant higher mean value for the KJRA in patients with a pathological TT-TG. Hence, a lateralized tibial tubercle as demonstrated by an increase in the TT-TG distance may be associated with a coexisting lower limb rotational malalignment.
