[How does trauma secondary to unexpected extreme weather affect orthopaedic surgery departments? : An epidemiological study on the Filomena snowstorm]. / Wie wirken sich Traumata infolge unerwarteter Wetterextreme auf orthopädisch-chirurgische Abteilungen aus? : Eine epidemiologische Studie über den Schneesturm Filomena.

INTRODUCTION: Trauma secondary to extreme weather events may heavily impact the normal activity of orthopaedic surgery departments, especially in places not prepared to deal with them. The Filomena snowstorm, which happened in January 2021, was one of the greatest snowstorms ever in Spain. During it, the constant influx of trauma patients caused Orthopaedic Emergencies Department (OED) to collapse. The primary objective of this study was to describe the orthopaedic injuries and changes in fracture's epidemiology observed during this exceptional period. Secondary objectives were to analyse the collected variables in order to minimize the future impact of these unexpected extreme weather events. MATERIAL AND METHODS: A retrospective cohort study between patients that came to the OED during the snowstorm (Filomena group) and those who came on the same period of the previous year (Control group) was made. The following data were collected: age, sex, injury location, injury mechanism, diagnosis, AO/OTA fracture classification, treatment type (conservative vs surgical) and delay of surgical treatment. RESULTS: A total of 1237 patients were included, 655 patients from the Filomena group and 582 from the Control group. One in two patients in the Filomena group sustained a fracture (50.7% vs 23.2%). The most frequent diagnosis on the Filomena group was distal radius fracture (16.2%), which was five times more frequent than in the Control group (3.4%). A significant increment was also observed in the incidence of ankle (21.7%) and proximal humerus (33%) fractures. In the Filomena group, surgically treated fractures increased by 168%, being more severe, as C­type fractures were more prevalent (23% vs 13%). Mean delay to surgery was 6.78 days during the snowstorm. CONCLUSION: Unexpected snowstorms entail an exponential rise in orthopaedic care demand and OED pressures. A significant increment in orthopaedic trauma surgery, up to 168% more, particularly distal radius, proximal humerus and ankle fractures, is to be expected, which will imply elective surgery cancellation, hurting patients and increasing costs.

Partial Two-Stage Exchange for Infected Total Hip Arthroplasty: A Treatment to Take into Account.

INTRODUCTION: Two-stage revision is the gold standard for chronic periprosthetic joint infection (PJI). The removal of well-fixed implants, especially the femoral component, can be extremely difficult and additional osteotomies may be needed, which is time-consuming and results in bone stock loss. When the femoral stem is osseointegrated, there is no clear indication for the use of partial two-stage revision. The primary objective was to assess infection eradication after surgery. METHODS: Retrospective study of specific case series. A total of eight patients with a chronic uncemented PJI, in the setting of complex revision surgeries, were treated with partial two-stage revision, which included selective retention of the well-fixed femoral component and complete acetabular removal. Stem retention was carried out regardless of the bacteria or associated comorbidities. RESULTS: All patients were re-revision cases with at least two previous surgeries (range, 2-4). Complex revisions were performed in five cases (non-articulated spacer) and simple revisions in three cases (articulated spacer). The minimum follow-up time was 24 months (range, 24-132 months). The infection eradication rate at final follow-up was 100%. CONCLUSION: Partial two-stage reconstruction is a promising technique for the treatment of chronic PJI in patients with a well-fixed stem and complex re-revision acetabular procedures. Further prospective studies and prolonged follow-ups are required to confirm our results.

Factors associated with mortality in older patients sustaining pelvic or acetabular fractures.

INTRODUCTION: This study aimed to investigate potential factors, including delay to surgical stabilisation, affecting mortality in older patients sustaining pelvic or acetabular (PA) fractures. MATERIALS AND METHODS: A retrospective review of the Trauma Audit and Research Network (TARN) database was performed to identify older patients (aged 65 and over) sustaining PA fractures treated surgically in a UK Major Trauma Centre (MTC) between 2015 and 2019. Chi-squared and Fisher tests were used to compare 1-year mortality rates following operative intervention between patients treated within 72 h and after 72 h. Kaplan-Meier curves were used to visualise survival probability; significant predictors of survival were found using Cox proportional hazard models. RESULTS: Of 564 older patients with PA fractures, 70 met the inclusion criteria. The mean age was 76.1 years. The overall 1-year mortality rate was 20%. When patients were grouped by time to surgery (fracture fixation within or greater than 72 h), there was no statistically significant difference in 1-year mortality. Patients whose surgery was delayed more than 72 h were more likely to have longer hospital stays (p = 0.002) or to have suffered from polytrauma (p = 0.025). Age, Charlson Co-morbidities Index (CCI) and pre-op mobility status were associated with statistically significant differences in overall mortality. The same factors were associated with a significantly increased hazard of death in the multivariate Cox proportional hazards model. Patient gender, mechanism of injury, Injury Severity Score (ISS) > 15 and head injury were not significant predictors of mortality. CONCLUSION: Surgical intervention within 72 h of injury did not result in decreased mortality in older patients with PA fractures. The 1-year mortality rate between older PA fractures and hip fractures was comparable. Consideration should be given to a combined multidisciplinary approach between orthogeriatric and expert PA surgeons for these patients.

Enhancing Preoperative Planning in Orthopedic Trauma Surgery Using a Presentation Software.

Preoperative planning (PP) is critical to ensure a successful outcome in orthopaedic trauma surgery. Since it was first described thirty years ago, no modifications have been made to the original preoperative planning (OPP) technique, which was written by hand using pen and paper. We believe that the use of presentation software (such as Microsoft PowerPoint, Microsoft Corp., Redmond, WA, US) can ease, improve and update the OPP and complement three-dimensional PP. The objective of the present paper is to describe our method for PP using a presentation software (PS).

Resumo O planejamento pré-operatório (PP) é fundamental para garantir um resultado bemsucedido na cirurgia de trauma ortopédico. Desde que foi descrita pela primeira vez há trinta anos, não foram feitas modificações na técnica de planejamento pré-operatório original (PPO), que foi escrita à mão usando caneta e papel. Acreditamos que o uso de um software de apresentação (como o Microsoft PowerPoint, Microsoft Corp., Redmond, WA, EUA) pode facilitar, melhorar e atualizar o PPO e complementar o PP tridimensional. O objetivo deste artigo é apresentar nosso método de PP por meio de software de apresentação (SA).
