ABSTRACT
Maintaining reduction of a calcaneal tuberosity avulsion fracture is challenged by the powerful force exerted upon the bone fragment by the Achilles tendon. Low-demand, elderly patients with osteoporotic bone usually undergo a low-energy mechanism when this fracture pattern occurs. Likely attributable to poor bone quality, the rate of early fixation failure has been documented to be as high as 40%. We present the cases of two 65-year-old female patients who each sustained a calcaneal tuberosity avulsion fracture. Both patients underwent a low-energy mechanism of injury and had a medical history of many comorbidities. The first patient underwent a partial calcaneal ostectomy and tenotomy after failing open reduction internal fixation (ORIF). The second patient primarily underwent a partial calcaneal ostectomy and tenotomy. Postoperatively, after the incision site was fairly healed, both patients could bear weight as tolerated. This method of excision and release may allow for decreased risk of skin compromise and return trips to the operating room for failed ORIF. In low-demand patients with low-energy calcaneal avulsion type fractures and osteoporotic bone, this technique may be the preferred surgical option.Copyright © 2022 The Author(s)
ABSTRACT
Objective: The coronavirus disease-2019 (COVID-19), caused by the novel severe acute respiratory syndrome coronavirus 2, started in Wuhan, China, and was recognized as a pandemic by the World Health Organization. In Iran, the first confirmed COVID-19 case was officially reported on February 19. The aim of this study was to investigate the epidemiological and clinical characteristics, and comorbid conditions, and determine risk factors for the mortality of COVID-19 patients as well as provide a comparison of the epidemiological features between the 3 waves of COVID-19 in the North-East of Iran from January 21, 2020, to March 20, 2021. Material(s) and Method(s): The current retrospective epidemiological population-based study was conducted on COVID-19 patients who were admitted to the hospitals affiliated to the Mashhad University of Medical Sciences in Razavi-Khorasan province, Iran. The data were extracted from the Medical Care Monitoring System of the Mashhad University of Medical Sciences. Result(s): In total, 43.6% of subjects had at least one coexisting underlying medical condition. The most common comorbidities were hypertension, diabetes, and cardiovascular diseases with the prevalence of 19.7, 15.1, and 13.3%;respectively. The overall case fatality rate was 15.0%, following a median of 4 days [interquartile range (IQR) 1-10] of hospitalization. The mean+/-SD and the median (IQR) of age in expired subjects were 67.40+/-18.27 and 70 (59-81) years;respectively. Conclusion(s): Our results demonstrated that age >60, male sex, loss of consciousness, respiratory distress, having at least one comorbidity, and diabetes were mortality risk factors among COVID-19 patients.Copyright © 2023 by Turkiye Klinikleri.
ABSTRACT
Using the event study methodology, we find that the stock returns of the Indian tourism sector reacted differently to the announcements of nationwide lockdown and the Unlock 1.0. Using the cross-sectional regression, we find liquidity, volatility, solvency, and size as the primary drivers of CARs during the event windows. The findings will empower the decision-making abilities of the investors and firm managers.
