Atrophic pseudarthrosis of humeral diaphyseal fractures: medico-legal implications and methodological analysis of the evaluation

Humeral shaft fractures account for 1- 3% of all fractures and about 20-27% of those involving the humerus. In the past they were often conservatively treated, with an acceptable consolidation rate. Open reduction and internal fixation (ORIF) is the best choice in polytrauma patients, in complex or pathological fractures and in those associated with vascular injuries. Regardless the type of fixation used, these fractures can evolve into delayed union or pseudarthrosis (PSA). It should be noted that the humeral shaft itself has a high intrinsic healing potential, due to the blood supply provided by the surrounding muscles. The aim of this work is to evaluate whether the causes that led to the development of atrophic pseudarthrosis in a humeral diaphyseal fracture are attributable to inadequate management of this fearful complication and to highlight the possible medico-legal repercussions. We will try to verify whether the currently used forensic evaluation parameters of permanent disability are appropriate and adequate in relation to the complexity of such injuries. This complexity also includes the repercussions on the ergonomic efficiency of the entire limb, the relative possible postural alterations, the inevitable extension of the period of traumatic illness and the relative repercussions on the overall compromised structure of the subject

Results obtained with level II oncoplastic surgery spanning 20 years of breast cancer treatment: Do we really need further demonstration of reliability?

Oncoplastic surgery (OPS) has demonstrated its superiority above traditional breast conserving surgery, but is still struggling to consolidate its role in breast cancer therapeutic protocols mainly because of contrasting scientific evidences and reduced follow-up results available. The objective of our contribution is to analyze results obtained with 381 patients consecutively treated in our Multidisciplinary Breast Center by means of level II OPS between January 1998 and January 2018 for unilateral, primary breast cancer. Surgical endpoints were mean specimen weight and volume, mean diameter of main lesion (MLD), rates of positive margins (PMR), re-excision (RR), conversion to mastectomy (CMR), complications (CR) and oncological endpoints as overall survival (OS), disease-free survival (DFS), and local recurrence rate (LR). About 29.1% were treated for multifocal/multicentric disease, and 29.1% previously underwent neo-adjuvant chemotherapy (NACT). Regarding surgical techniques, 53.0% of patients received "inverted T" and 30.1% "J" mammoplasties, whereas 13.6% underwent "round block," 2.3% "Grisotti," and 1% "batwing" techniques. Regarding surgical outcomes, mean specimen weight was 215 g (50-2157) and volume 345 mm3 (21-7980). MLD 23 mm, PMR 7.6%, RR 3.6%, CMR 1.6%, and CR 5.8%. With a mean follow-up of 118 months, oncological outcomes were: OS 93.7%, DFS 82.3%, LR 4.4%. In conclusion, our analysis confirmed level II OPS reliability even for longer follow-up timing and in difficult situations as multifocal disease or after NACT

Spinal cord injuries in the absence of post-traumatic radiographic anomalies (SCIWORA). The traumatic moment between patient anterior state and efficient/concurrent causes of injury

Background and aim: Spinal Cord Injury without Radiographic Abnormality (SCIWORA) represents acute traumatic myelopathy in the absence of instrumental evidence of fractures and/or dislocations of the cervical vertebrae. Methods: In this article we present 4 cases of SCIWORA that came to our observation and the medico-legal implications associated with them. Results: In defining the compensation in the context of a private accident policy for traumatic pathologies of the spinal cord, an in-depth medical-legal assessment is essential, based on an accurate examination of the health documentation including the instrumental investigations performed, the anamnesis and an accurate evaluation of the trauma dynamic. The paraphysiological deterioration of organ-tissue structures, identifiable in the concept of "natural variability of biological risk", should be included in the same definition of insured risk by age group, with the consequence that physical conditions that fall within the physiological or paraphysiological definitions, although potentially contributing to injury, do not necessarily exclude compensation. A different concept dominates the variability of the compensation according to a paraphysiological pre-existing condition. The two arguments therefore call for thorough consideration of both the paraphysiological contributing causes of injury and/or impairment as necessarily subject to a preliminary study, which through the clinical and instrumental investigation method, will define the perimeter of functionality

COVID-19 Elderly Patients Treated for Proximal Femoral Fractures during the Second Wave of Pandemic in Italy and Iran: A Comparison between Two Countries

Background and objevtive: The worldwide spread of SARS-CoV-2 has affected the various regions of the world differently. Italy and Iran have experienced a different adaptation to coexistence with the pandemic. Above all, fractures of the femur represent a large part of the necessary care for elderly patients. The aim of this study was to compare the treatment in Italy and Iran of COVID-19-positive patients suffering from proximal femur fractures in terms of characteristics, comorbidities, outcomes and complications. Materials and Methods: Medical records of COVID-19-positive patients with proximal femoral fractures treated at IRCCS Istituto Ortopedico Galeazzi in Milan (Italy) and at Salamat Farda and Parsa hospitals in the province of Tehran (Iran), in the time frame from 1 October 2020 to 16 January 2021, were analyzed and compared. Results: Records from 37 Italian patients and 33 Iranian patients were analyzed. The Italian group (mean age: 83.89 ± 1.60 years) was statistically older than the Iranian group (mean age: 75.18 ± 1.62 years) (p value = 0.0003). The mean number of transfusions for each patient in Italy was higher than the Iranian mean number (p value = 0.0062). The length of hospital stay in Italy was longer than in Iran (p value < 0.0001). Furthermore, laboratory values were different in the post-operative value of WBC and admission and post-operative values of CRP. Conclusions: The present study shows that differences were found between COVID-19-positive patients with proximal femoral fractures in these two countries. Further studies are required to validate these results and to better explain the reasons behind these differences

Traumatology: Adoption of the Sm@rtEven Application for the Remote Evaluation of Patients and Possible Medico-Legal Implications

Telemedicine is the combination of technologies and activities that offer new remote ways of medical care. The Sm@rtEven application project is a remote assistance service that follows patients affected by lower limb fractures surgically treated at Galeazzi Orthopedic Institute (Milan, Italy). The Sm@rtEven application aims to evaluate the clinical conditions of patients treated for lower limb fracture after discharge from hospital using remote follow-up (FU). The project is not a substitute for traditional clinical consultations but an additional tool for a more complete and prolonged view over time. The Sm@rtEven application is installed on patients’ smartphones and is used daily to communicate with healthcare personnel. In the first protocol, patients had to complete different tasks for 30 days, such as monitoring the load progression on the affected limb, the number of steps during the day, and body temperature and completing a questionnaire. A simplified protocol was proposed due to the pandemic and logistical issues. The revised protocol enrolled patients after more than 30 days of their operation, prioritized the rehabilitation phase, and required patients to use the app for fewer days. After an initial phase of correct use, a reduction in patient compliance was gradually reported in the first protocol. However, patient compliance in the second protocol remained high (96.25%) in the recording of all the required parameters. The Sm@rtEven application has proven to be a valuable tool for following patients remotely, especially during the pandemic. Telemedicine has the same value as traditional clinical evaluations, and it enables patients to be followed over long distances and over time, minimizing any discomfort

A Panel Study on Lung Function and Bronchial Inflammation among Children Exposed to Ambient SO₂ from an Oil Refinery

To determine the acute effects on respiratory function of children exposed to sulphur dioxide (SO2), we conducted two population-based longitudinal investigations near a major oil refinery. We enrolled 233 children, age 8–14, in Sarroch (Italy). The first study entailed five monthly spirometric visits (Panel 5). In a subgroup, children positive for history of respiratory symptoms were tested weekly (20 times) with spirometry and fractional exhaled nitric oxide (FeNO) measurement (Panel 20). Baseline questionnaires and daily diaries were recorded. SO2, NO2, PM10 and O3 were measured by monitoring stations. Multiple regression models were fitted. Using a multipollutant model, we found that a 10 µg/m3 SO2 increase at lag0–2 days determined a percent variation (PV) of −3.37 (90% confidence interval, CI: −5.39; −1.30) for forced expiratory volume after one second (FEV1) in Panel 5 and a PV = −3.51 (90% CI: −4.77; −2.23) in Panel 20. We found a strong dose-response relation: 1-h SO2 peaks >200 µg/m3 at lag2 days = FEV1 PV −2.49. For FeNO, we found a PV = 38.12 (90% CI: 12.88; 69.01) for each 10 µg/m3 SO2 increase at 8-h time lag and a strong dose-response relation. Exposure to SO2 is strongly associated with reduction of lung function and an increase in airway inflammation. This new evidence of harmful effects of SO2 peaks should induce regulatory intervention

Treatment of Femoral Shaft Pseudarthrosis, Case Series and Medico-Legal Implications

Pseudarthrosis (PSA) is a possible complication of femoral shaft fracture treatment. It is often associated with reduced bone quality and can, therefore, adversely affect quality of life. Its treatment poses a major challenge for orthopaedic surgeons. Several authors have set forth different surgical approaches for the treatment of pseudarthrosis, such as internal fixation with plate and screws, replacement of an intramedullary nail or prosthetic replacement. In cases associated with bone loss, osteopenia, or comminution of fracture fragments, autologous or homologous bone grafts may also be used. The chronic outcomes of the surgical treatment of femoral shaft pseudarthrosis, even when consolidation is achieved, are linked to disabling sequelae of clinical-functional relevance, deserving an adequate medico-legal evaluation. The purpose of this retrospective study is to analyse a clinical case series of patients treated for atrophic femoral shaft pseudarthrosis at the IRCCS Orthopaedic Institute Galeazzi, Milan, Italy, from 2014 to 2020 and their orthopaedic-traumatological and medico-legal implications

How the COVID-19 Pandemic Affected Attendance at a Tertiary Orthopedic Center Emergency Department: A Comparison between the First and Second Waves

Italy was the first European country to face the SARS-CoV-2 virus (COVID-19) pandemic in 2020. The country quickly implemented strategies to contain contagions and re-organize medical resources. We evaluated the COVID-19 effects on the activity of a tertiary-level orthopedic emergency department (ED) during the first and second pandemic waves. We retrospectively collected and compared clinical radiological data of ED admissions during four periods: period A, first pandemic wave; period B, second pandemic wave; period C, three months before the COVID-19 outbreak; period D, same timeframe of the first wave but in 2019. During period A, we found a reduction in ED admissions (−68.2% and −59.9% compared with periods D and C) and a decrease in white codes (non-urgent) (−7.5%) compared with pre-pandemic periods, with a slight increase for all other codes: +6.3% green (urgent, not critical), +0.8% yellow (moderately critical) and +0.3% red (highly urgent, risk of death). We observed an increased rate of fracture diagnosis in period A: +14.9% and +13.3% compared with periods D and C. Our study shows that the COVID-19 pandemic caused a drastic change in the ED patient flow and clinical radiological activity, with a marked reduction in admissions and an increased rate of more severe triage codes and diagnosed fractures

Evaluation of retinal ganglion cell layer in patients with macular edema treated with intravitreal anti-VEFG and corticosteroid

Purpose: The aim of the study is to detect the effect of the different intravitreal therapies (anti-VEFG drugs and corticosteroids) on the single layer of retinal ganglion cells (GCL) in patients affected by macular edema. Methods: Forty (17 males/23 females) Caucasian patients (40 eyes) affected by macular edema treated with intravitreal injections (anti-VEGF and steroids) are included. Spectralis HRA-OCT device with a specific protocol for the acquisition and evaluation of the GCL layer has been used. Macular GCL thickness is assessed with automated retinal segmentation based on ETDRS grid rings. Retinal layer automated segmentation is carefully assessed and manually corrected for any misalignment. GCL measurements are correlated with best-corrected visual acuity (BCVA) measured with Early Treatment Diabetic Retinopathy Study (ETDRS), central macular thickness (CMT) and intraocular pressure (IOP). All patients have been evaluated at baseline and at the subsequent follow-up: 4 weeks, 8 weeks and 12 weeks. Results: Neither anti-VEFG drugs (Bevacizumab, Ranibizumab and Aflibercept) nor corticosteroids (Dexametasone) has a significant effect on GCL layers during three months of follow up compared to long-term treatments. A significant correlation between GCL and ETDRS has found (p=0.0453, R2=0.023). Conclusions: This study shows that anti-VEFG drugs and corticosteroids do not significantly affect GCL layer over three months of treatment. This study also demonstrates that the ganglion cell layer is correlated to visual acuity, an important factor for future investigations on the effects of new treatments
