Electric scooter-related orthopedic injuries: the experience of an Italian orthopedic center and literature review
Background With the increasing prevalence of electric scooters, a concomitant increase in the number of specific injuries, emergency department (ED) admissions and hospital admissions have been reported.Objectives Analyze patient flow changes in the ED with a focus on e-scooter-related injuries through a case series and a comparison with the contemporary literature.Data sources A systematic literature review was performed on Medline/PubMed and Embase using terms related to the topic. Data collected from two-wheeled vehicle trauma patients at our Italian ED from May 1 to October 31, 2021, were analyzed for the case series.Data sources A systematic literature review was performed on Medline/PubMed and Embase using terms related to the topic. Data collected from two-wheeled vehicle trauma patients at our Italian ED from May 1 to October 31, 2021, were analyzed for the case series.Study eligibility criteria Studies were included if they evaluated populations with an e-scooter-related injury referred to the ED with precise localization and nature of the injury reported.Participants and interventions Data collected from the literature studies and from our case series included overall ED patient numbers, patient demographics, injury mechanism, location of the injury, discharge diagnosis, and performance of surgery.Study appraisal and synthesis methods All studies were checked in order to establish the coherence with the purposes of this review. Data from the contemporary literature and from this case series were compared.Results During a 6-month period, 280 patients had e-scooter injuries, resulting in 292 traumas, including 123 fractures, primarily in the elbow. Surgical intervention was necessary for 28 patients. The review included nine papers, highlighting that injuries to the upper and lower extremities and head were frequent in e-scooter-related incidents. The upper extremities were the most common fracture location.Limitations The study is a retrospective, single-center study without a comparison group, focusing exclusively on orthopedic injuries.Conclusions or implications of key findings The prevalence of electric scooters, which offer an affordable and eco-friendly mode of transport, is steadily increasing. It is important to focus on injury risk mitigation through effective public health policies, thereby lowering costs to society
Mario Luzi E L’arte: Da Simone Ai Contemporanei
This contribution deals with Luzi’s career as a connoisseur and critic of figurative arts: starting from Luzi’s precocious piece of criticism on Raffaello, the author investigates other works by the Italian writer dealing with art history, theatre and poetry. The works of great artists like Simone Martini, Jacopo Carracci (alias Pontormo) and Giorgio De Chirico were a source of inspiration for Luzi’s Viaggio celeste e terrestre di Simone Martini, Felicità turbate and Avvento notturno. The paper ends with a critical reassessment of Luzi’s friendship with the contemporary painter, Pietro Paolo Tarasco, whose drawings and engravings accompanied Luzi’s final books
Tra la Vita e la Morte: Simone di Filippo e Pietro di Giovanni Lianori per i Battuti bolognesi
The article focuses on some new findings regarding the supposed activity of Simone di Filippo (Bologna, documented from 1354, dead in 1399), the most productive Bolognese painter of the latter half of the 14th Century, also known as Simone dei Crocifissi, for the local confraternities of Santa Maria della Vita and Santa Maria della Morte. A sacred image of the Virgin and Child now visible above the high altar of Santa Maria della Vita was attributed to Simone in the 17th Century. However, an unknown 18th-Century author has already considered the painting as close to the Madonna in Fiesso di Castenaso (Bologna), signed by Pietro di Giovanni Lianori (Bologna, documented 1406-1466), one among the protagonists of late-gothic painting in Bologna in the first half of the 15th Century. As I have recently argued, the Madonna della Vita shows a style updated to Bolognese late-gothic artistic trends and can thus be attributed to Lianori himself. On the other hand, thanks to the discovery of an 18th-Century record, it is possible to advance that the cross signed by Simone now held in the church of Santo Stefano was commissioned by the confraternity of Santa Maria della Morte

The Role of the Critical Coronoid Angle in Simple Elbow Dislocation: A Computed Tomography-Based Index to Stratify Elbow Dislocation Risk
Introduction: Elbow primary stability is guaranteed by the anatomical congruency between the humeral trochlea and the greater sigmoid notch (GSN). Elbow dislocation typically occurs in a semi-extended position, but computed tomography (CT) scans are typically acquired at 90 degrees of elbow flexion, which may misleadingly suggest that the apex of the coronoid aligns with the trochlear center of rotation. This study aims to evaluate the anatomical features of the coronoid and GSN in a dislocated versus non-dislocated group, demonstrating that a more prominent coronoid process is more commonly observed in elbows without dislocation compared to those with dislocation. Materials and Methods: A total of 50 CT scans, equally divided between dislocated elbows and non-dislocated elbows, were analyzed, and the critical coronoid angle (CCA) was measured on a specific slice of the CT scan (level of evidence III). The CCA was calculated from two lines that arise in the center of the GSN, with the first one crossing the coronoid tip and the second parallel to the posterior olecranon cortex. Results: A significant difference in the CCA (p < 0.001) between the two groups was highlighted. In particular, it was found that 14/25 patients from the dislocated elbow group had a CCA below or equal to 27 degrees, and all the non-dislocated subjects had a CCA >= 27 degrees. These preliminary results suggest that a CCA <= 27 degrees could be a threshold for requiring further imaging of soft tissues or closer follow-up. This may result from either a hypoplastic coronoid process or a decreased concavity of the GSN. Based on the CCA values, a logistic regression model (DAM model) was proposed to associate a coefficient of protection to the CCA, the angle of flexion during dislocation (FdD), and a parameter X, which is a factor that encompasses the contribution of soft tissues. Conclusions: A low CCA is statistically more frequent in dislocated elbows versus non-dislocated ones, creating a specific anatomical condition. The CCA should be carefully evaluated by elbow surgeons to guide patient-specific treatment. The DAM model can permit the stratification of patients eligible for further diagnostic analysis
Fibromyalgia and Shoulder Surgery : a Systematic Review and a Critical Appraisal of the Literature
Fibromyalgia is a common musculoskeletal syndrome characterized by chronic widespread pain and other systemic manifestations, which has demonstrated a contribution to higher postoperative analgesic consumption to other surgeries such as hysterectomies and knee and hip replacements. The aim of this review is to search current literature for studies considering the impact of fibromyalgia on clinical outcomes of patients undergoing shoulder surgery. A systematic literature review was conducted in PubMed/Medline, Embase, and ClinicalTrials.gov in February 2019. Studies were selected based on the following participants, interventions, comparisons, outcomes, and study design criteria: adult patients undergoing surgery for shoulder pain (P); diagnosis of fibromyalgia (I); patients without fibromyalgia (C); outcome of surgery in terms of pain or analgesic or non-steroidal anti-inflammatory drugs consumption (O); case series, retrospective studies, observational studies, open-label studies, randomized clinical trials, systematic reviews and meta-analyses were included (S). Authors found 678 articles, of which four were found eligible. One retrospective study showed that patients with fibromyalgia had worse clinical postoperative outcomes; two retrospective studies reported a higher opioid prescription in patients with fibromyalgia and one prospective observational study found that a higher fibromyalgia survey score correlated with lower quality of recovery scores two days after surgery. The scarce and low-quality evidence available does not allow confirming that fibromyalgia has an impact on postoperative outcomes in shoulder surgery. Future studies specifically focusing on shoulder surgery outcomes may help improvement and personalization of the management of patients with fibromyalgia syndrome (PROSPERO 2019, CRD42019121180)

Platelet-rich plasma does not improve clinical results in patients with rotator cuff disorders but reduces the retear rate. A systematic review and meta-analysis
Purpose: To assess whether the use of Platelet-rich plasma (PRP) produces a clinical benefit in patients with rotator cuff disorders, treated either conservatively or surgically. Methods: A systematic review was performed according to PRISMA guidelines on three databases (PubMed, Cochrane Library, Web of Science) to identify randomised controlled trials (RCTs) on the use of PRP in patients with rotator cuff disorders, treated either conservatively or surgically. A meta-analysis was performed on articles reporting results for Constant, UCLA, VAS, SST scores and retear rate. The RoB 2.0 and the modified Coleman Methodology Score were used to assess methodological quality. Results: A total of 36 RCTs (20 surgical, 16 conservative) were included, for a total of 2,443 patients. Conservative treatment showed high heterogeneity and no clear consensus in favour of PRP. The meta-analysis of the studies with surgical treatment showed no benefit in using PRP in any of the clinical outcomes, either at the short or medium/long-term follow-up. However, the retear rate was lower with PRP augmentation (p < 0.001). The overall quality of the studies was moderate to high, with the surgical studies presenting a lower risk of bias than the conservative studies. Conclusion: The use of PRP as augmentation in rotator cuff surgical repair significantly reduces the retear rate. However, no benefits were documented in terms of clinical outcomes. PRP application through injection in patients treated conservatively also failed to present any clear advantage. While there are many studies in the literature with several RCTs of moderate to high quality, the high heterogeneity of products and studies remains a significant limitation to fully understanding PRP potential in this field. Level of evidence: Level I
No neurovascular damage after creation of an accessory anteromedial portal for arthroscopic reduction and fixation of coronoid fractures
Purpose: Arthroscopic reduction and internal fixation for coronoid process fractures has been proposed to overcome limitations of open approaches. Currently, arthroscopy is most frequently used to assist insertion of a retrograde guide wire for a retrograde cannulated screw. The present anatomical study presents an innovative arthroscopic technique to introduce an antegrade guide wire from an accessory anteromedial portal and evaluates its safety and reproducibility. Methods: Six fresh-frozen cadaver specimens were obtained and prepared to mimic an arthroscopic setting. The coronoid process was localized and a 0.9 mm Kirschner wire was introduced from an accessory anteromedial portal, located 2 cm proximal to the standard anteromedial portal. At the end of the procedure, a lateral radiograph was taken to verify the Kirschner wire position and open dissection was conducted to evaluate possible damage to neurovascular structures. Results: The Kirschner wire was drilled without complications in the coronoid process of all six specimens. Damage of the brachial artery, the median nerve, and the ulnar nerve did not occur in any specimen. A corridor between the brachialis muscle, the median intermuscular septum, and the pronator teres could be identified as suitable for the wire passage. Conclusion: This study presents a safe and reproducible technique combining the possibility to introduce a guide wire from the anteromedial part of the coronoid, under direct visual control, with a completely arthroscopic approach. This wire can guide the introduction of a retrograde cannulated screw from the dorsolateral ulna to the tip of the coronoid. This new arthroscopic approach permits to obtain improved visual control over coronoid process fixation, without endangering neurovascular structures
