Purpose The current pandemic caused by COVID-19 is the biggest challenge for national health systems for a century. While most medical resources are allocated to treat COVID-19 patients, fractures still need to be treated, as some patients with nondeferrable pathologies. The aim of this paper is to report the early experience of an integrated team of orthopaedic surgeons during this period. Material and methods This is a mono-geographic, observational, retrospective, descriptive study. We collected data from the beginning of the epidemic (1 March 2020), during the pandemic lockdown period (declared in the country on March 16, 2020) until the end of our study period on April 15, 2020. All the 140 patients presented to the Emergency Department of the hospital during this period with a diagnosis of fracture, or trauma (sprains, dislocations, wounds) were included in the cohort. In addition, 12 patients needing hospitalization for planning a non-deferrable elective surgical treatment were included. A group of patients from the two same hospitals and treated during the same period (1 st March 2018 to April 15, 2018) but previously was used as control.Results Of these 152 patients (mean age 45.5 years; range 1 to 103), 100 underwent a surgical procedure and 52 were managed non-operatively. Twenty-eight were children and 124 were adults. The COVID-19 diagnosis was confirmed for four patients. The frequency of patients with confirmed COVID-19 diagnosis among this population treated in emergency was ten fold higher (2.6%; 4 among 152) than in the general population (0.30%) of the country. The mortality rate for patients with surgery was 2% (2 of 100 patients) and 50% (2 of 4) for those older than 60 years with COVID-19; it was null for patients who were managed non-operatively. As compared to the year 2018, the number of patients seen with trauma had decreased of 32% during the epidemic. Conclusion Staying home during the COVID-19 pandemic decreased trauma frequency of 32%. The structural organization in our hospital allowed us to reduce the time to surgery and ultimately hospital stay, thereby maximizing the already stretched medical resources available to treat all the patients who needed orthopedic care during this period.

Purpose The purpose of this study was to evaluate the impact of tobacco abuse in the consolidation of fractures. Methods We retrospectively identified all patients with a diaphyseal fracture (femur, tibia, or humerus), between January 1999 and December 2010, in our orthopaedic trauma registry (Erasme hospital, Brussels, Belgium). Thirty-eight diaphyseal nonunions (ten femurs, 16 tibias and 12 humerus) were identified. Each nonunion was paired (on age, sex and location) with two control-healed fractures (76 control patients). The chi-squared test and a binary logistic regression were used for statistical analysis. Results In multivariate analysis, smoking (tobacco use) was significantly associated with nonunion, whether the fracture was open or closed (p<0.01). In univariate analysis, open fracture was associated with a higher risk of nonunion (p<0.05), while external fixation was associated with better bone healing (p<0.05). Conclusion Tobacco is confirmed as a deleterious factor for diaphyseal bone healing.

The humeral head is the second most common site for nontraumatic osteonecrosis after the femoral head, yet it has attracted relatively little attention. Osteonecrosis is associated with many conditions, such as traumatism, corticosteroid use, sickle cell disease, alcoholism, dysbarism (or caisson disease), and Gaucher's disease. The diagnosis is clinical and radiographic with MRI, with radiographs being the basis for staging. Many theories have been proposed to decipher the mechanism behind the development of osteonecrosis, but none have been proven. Because osteonecrosis may affect patients with a variety of risk factors, it is important that caregivers have a heightened index of suspicion. Early detection may affect prognosis because prognosis is dependent on the stage and location of the disease. In particular, the disease should be suspected in patients with a history of fractures, steroid usage, or sickle cell disease, and in divers. This report reviews osteonecrosis of the humeral head, with an emphasis on causes, clinical evaluation, imaging, and classification.

Objectives The aim of this study was to review the impact of smoking tobacco on the musculoskeletal system, and on bone fractures in particular. Methods English-language publications of human and animal studies categorizing subjects into smokers and nonsmokers were sourced from MEDLINE, The Cochrane Library, and SCOPUS. This review specifically focused on the risk, surgical treatment, and prevention of fracture complications in smokers. Results Smokers have an increased risk of fracture and experience more complications with delayed bone healing, even if they have already stopped smoking, because some adverse effects persist for a prolonged period. Some risks can be reduced during and after surgery by local and general prevention, and smoking cessation is an important factor in lessening this risk. However, if a patient wants to stop smoking at the time of a fracture, the cessation strategies in reducing tobacco use are not easy to implement. The patient should also be warned that using e-cigarettes or other tobaccos does not appear to reduce adverse effects on health. Conclusion The evidence reviewed in this study shows that smoking has a negative effect in terms of the risk and treatment of fractures. Cite this article: J. Hernigou, F. Schuind.
