PurposeThe incidence of paediatric fractures is known to peak during the summer as a consequence of unsupervised physical activity. A more sedentary lifestyle is a potential cause for changes in paediatric seasonal fracture frequency and severity. The aim of this study was to evaluate the current seasonal variations of paediatric fractures in order to determine resource allocation in hospitals, community clinics and prevention programs.MethodsA single institutional review of historical data of all patients aged 0 to 16 years that were diagnosed with fractures between April 2014 and July 2017 in the emergency department of a level 3 orthopaedic trauma centre was conducted. In all, 3484 fractures were reviewed, of which 2991 were included. We stratified fractures according to patients’ variants and the hour, day and month with respect to holidays, weekends and weather.ResultsWhile the fracture rate on school days was 6.62 per day, the fracture rate during the summer vacation was 4.45 (p < 0.01). Hot weather was correlated with low fracture rates. The peak hours of admission were 12:00 to 13:00 and 18:00 to 22:00, with more moderate differences during non-school periods.ConclusionThe local seasonal variation of paediatric fractures has a bimodal distribution, with similar nadirs during both summer and winter. These rates might reflect a shift to a more sedentary lifestyle during the summer vacation. The presented data can assist in improving the value of injury prevention measures and medical resources allocation.Level of evidence:II
BackgroundThere is no consensus regarding the proper radiographic protocol following closed or open reduction and internal fixation for intertrochanteric femoral fractures. The objective of this study was to assess the role of early postoperative imaging studies when deciding about weight bear limitations and reoperations.MethodsA prospective cohort study of 100 patients (26 men and 74 women, at a mean age of 79.8 years) treated by closed or open reduction and internal fixation for AO31A fractures was conducted. According to the AO classification, there were 25 cases of 31A1, 54 cases of 31A2, and 21 cases of 31A3. For every patient, the intraoperative fluoroscopy studies were recorded and post-operative radiograms were taken during the first week. Excluded were patients for whom the early X-rays were clinically indicated. The intraoperative AP and axial fluoroscopy studies were compared with the radiograms taken during the first post-operative week. The investigators compared the decisions regarding weight-bearing limitations and the need for re-operation before and after conducting the radiograms.ResultsThe early post-operative imaging studies did not change weight-bearing limitations nor did they lead to consecutive surgical treatments.ConclusionsUnless indicated by physical examination, there is no value to routine post-operative radiograms within the first few days after closed reduction and internal fixation of intertrochanteric femoral fractures with regard to weight-bearing limitations and re-operation decisions.Trial registrationIdentifier: NCT02868125.
