- Abstract
Background: In recent years, the medical community has witnessed a notable increase in high-energy traumatic injuries, leading to a surge in complex fracture patterns that challenge existing treatment methodologies. Among these, the posterior approach to acetabular fractures stands out for offering direct visualization of the retro-acetabular surface, with current fixation methods relying on 3.5 mm low-profile reconstruction plates and various other implants. Despite the effectiveness of these methods, there is a burgeoning demand for a singular, adaptable implant that not only streamlines the surgical process but also optimizes patient outcomes., Methods: In an innovative approach to address this need, three-dimensional (3D) models of the posterior acetabular wall were meticulously crafted using AutoCAD® software. The chosen material for the implant was 316L surgical steel for its durability and strength. The design of the implant featured a low-profile mesh structure, which was instrumental in facilitating osteosynthesis. This design allowed for the placement of screws of varying lengths in multiple directions, ensuring the initial reconstruction of the joint in an anatomical position without hindering the placement of the definitive implant. The primary objective was to secure the fixation and stabilization of the fracture by specifically targeting the smaller bone fragments. A comparative analysis was then conducted between this novel plate and a conventional 316L surgical steel, seven-hole, 3.5 mm reconstruction plate through finite element analysis., Results: The comparative analysis unveiled that both plates demonstrated comparable deformation capacities, with no significant differences in load-bearing capabilities observed. This finding suggests that the innovative plate can match the performance of traditional plates used in such surgeries., Conclusions: The finite element analysis revealed that the newly developed anatomical plate for posterior wall acetabular fractures meets the necessary physical and mechanical criteria for permanent implementation in patients with these fractures. This breakthrough represents a promising advancement that could simplify surgical procedures and potentially elevate patient outcomes., Level of Evidence Ii: This study is classified as a Level II, diagnostic study., (© 2024.

- Abstract
Introduction: Isolated fractures of the iliac wing are a rare injury, usually occurring in high-energy trauma, and are associated with other non-musculoskeletal and soft tissue injuries that could compromise the patient's life. Surgical indications are unclear, and there is limited information on the most frequent fracture patterns., Methods: A descriptive multicenter case series study of isolated fractures of the iliac wing treated surgically in three referral trauma hospitals in Latin America. The different fracture patterns are described, the "iliac ring" concept is proposed, and a classification is made., Results: Twenty-eight patients were included; 24 were male, the median age was 31 years RIQ (24-46), the most frequent trauma mechanism was a traffic accident, and in 14 patients, the ISS >16. The most frequent associated injury was to the appendicular skeleton at another level in 13 patients. In the new classification, according to the number of fragments, 11 patients were classified as type A (1 fragment), ten patients as type B (two fragments), and seven patients as type C (three or more fragments). The most compromised anatomical area was the crest and anterosuperior iliac spines in 26 patients, followed by the fossa and anteroinferior iliac spine in 17 and 8 patients, respectively., Discussion: The patterns of isolated fractures of the iliac wing allow the identification of three types of fractures. Identifying these patterns can help the surgeon decide to perform surgery in these scenarios and choose the fixation technique according to the number and location of the fragments., Competing Interests: Declaration of Competing Interest The authors declare no conflict of interest related to content of this article., (Copyright © 2023.

- Abstract
Objective: The aim of this study was to evaluate the Latin American orthopaedic trauma surgeons preference regarding knee positioning and entry portals for IM nailing and identify the reasons of these preferences., Methods: Using the AO Trauma database, 22.285 surveys were distributed by email to Latin American orthopaedic surgeons. Demographic data and practice patterns, especially regarding knee positioning and approach for tibial nailing, were then evaluated and statistically treated., Results: amongst one thousand five hundred fourteen responses, 990 orthopaedic surgeons (4.4% of response rate) fully responded to the survey. Transpatellar tendon approach (613 / 61.9%,) with the knee in flexion (518 / 52.3%) on a radiolucent table remains the standard practice for intramedullary tibial nailing. Even for proximal and distal tibial nailing, the transpatellar tendon approach (455 / 46%) with the knee in flexion (562 / 56.8%) hold on the most used method. Only 55 (9.36%) orthopaedic surgeons reported that they have migrated to the supra-patellar tibial nailing in the recent years. The main reasons for a low rate of migration were lack of knowledge about the technique and unavailability of specific gigs and cartilage protectors for a safe suprapatellar nailing., Conclusion: Even with the potential benefits of the semi-extended knee positioning for tibial nailing, the Latin American orthopaedic community remains using the transpatellar tendon approach with the knee in flexion as the standard technique. Lack of surgical training for suprapatellar and parapatellar approaches with the knee in semi-extension, added by the unavailability of suprapatellar jigs and soft outer protection sleeves contribute to counter the trend towards the semi-extended techniques., Competing Interests: Declaration of Competing Interest The authors of the study “Is there a trend towards semi-extended knee positioning during intramedullary tibial nailing in Latin America? A survey amongst 990 orthopaedic surgeons” declare that they have no conflict of interest related to this manuscript., (Copyright © 2023 Elsevier Ltd. All rights reserved.)

- Abstract
Determining the true availability of resources and understanding the level of training of surgeons involved in the treatment of patients with pelvic fractures and haemorrhagic shock is critical. In the herein study, the availability of technical, technological, and human resources for the care of this injury in Latin America region was analysed, and the preferences of orthopaedic trauma surgeons when performing interventions for the diagnosis and treatment of patients with pelvic trauma and associated haemorrhagic shock was described. A cross sectional web-based survey containing questions on knowledge, attitudes, and practices with respect to imaging resources, emergency pelvic stabilization methods, and interventions used for bleeding control was sent to 948 Latin America orthopaedic trauma surgeons treating pelvic fractures in the emergency department. Differences between regional clusters, level of training, type of hospital, and pelvic surgery volume were assessed. 368 responses were obtained, with 37.5% of respondents reporting formal training in pelvic surgery and 36.0% having available protocol for managing these patients. The most frequently used interventions were the supra-acetabular pelvic external fixator and pelvic packing. Limited hospital and imaging resources are available for the care of patients with pelvic trauma and associated haemorrhagic shock throughout Latin America. In addition, the training of orthopaedic trauma surgeons dealing with this type of injury and the volume of pelvic surgeries per year is heterogeneous. It should be urgently considered to develop management protocols adapted to Latin America according to the availability of resources, as well as to promote training in this severe life-threatening traumatic condition., Competing Interests: Declaration of Competing Interest The authors declare no conflict of interest related to the content of this article., (Copyright © 2023 Elsevier Ltd.

- Abstract
Purpose: To systematically review the currently available existing evidence related to the presentation and management of simultaneous floating hip and knee injuries to identify injury characteristics, treatment strategies, and complications., Methods: Data sources: Relevant articles were identified by searching Medline, PubMed, and Google Scholar databases with no language restrictions. Manual searches of other relevant databases (SciELO and grey literature databases) and reference lists of primary articles found from initial searches were also conducted., Study Selection: All types of study designs published from January 1st, 2000 to October 1st, 2022 involving skeletally mature patients with simultaneous floating hip and knee injuries were included., Data Extraction: Basic information and specific injury-related information were collected., Results: Eight case reports were included. No study adequately reported the case with sufficient detail to allow other investigators to make inferences, nor was the result properly calculated, nor was the follow-up considered adequate for adequate functional assessment to occur in 80% of the studies., Conclusion: The exact treatment strategy and the follow-up time are not uniform across the included studies; therefore, they are not sufficient to adequately recommend surgical approach, timing of fixation, and fixation method. Our findings warrant the need for better documentation and reporting information about the mode of treatment of simultaneous floating hip and knee injuries., (© 2023.

- Abstract
Superior pubic rami fractures are commonly associated with a posterior pelvic ring disruption. It has been shown that fixing both the anterior pelvic arch and the posterior ring increases stability and enhances clinical results. Several techniques for fixing the superior pubic rami exist, and multiple studies showed that minimally invasive methods decrease wound-related complications, with the advantage of preserving soft tissues. We describe a surgical procedure to treat simple pubic rami fractures associated with posterior pelvic ring disruptions by placing an intramedullary elastic titanium nail (TEN). We propose this technique as an alternative fixation method for superior pubic rami fractures.

- Abstract
With a lot of uncertainty, unclear, and frequently changing management protocols, COVID-19 has significantly impacted the orthopaedic surgical practice during this pandemic crisis. Surgeons around the world needed closed introspection, contemplation, and prospective consensual recommendations for safe surgical practice and prevention of viral contamination. One hundred orthopaedic surgeons from 50 countries were sent a Google online form with a questionnaire explicating protocols for admission, surgeries, discharge, follow-up, relevant information affecting their surgical practices, difficulties faced, and many more important issues that happened during and after the lockdown. Ten surgeons critically construed and interpreted the data to form rationale guidelines and recommendations. Of the total, hand and microsurgery surgeons (52%), trauma surgeons (32%), joint replacement surgeons (20%), and arthroscopy surgeons (14%) actively participated in the survey. Surgeons from national public health care/government college hospitals (44%) and private/semiprivate practitioners (54%) were involved in the study. Countries had lockdown started as early as January 3, 2020 with the implementation of partial or complete lifting of lockdown in few countries while writing this article. Surgeons (58%) did not stop their surgical practice or clinics but preferred only emergency cases during the lockdown. Most of the surgeons (49%) had three-fourths reduction in their total patients turn-up and the remaining cases were managed by conservative (54%) methods. There was a 50 to 75% reduction in the number of surgeries. Surgeons did perform emergency procedures without COVID-19 tests but preferred reverse transcription polymerase chain reaction (RT-PCR; 77%) and computed tomography (CT) scan chest (12%) tests for all elective surgical cases. Open fracture and emergency procedures (60%) and distal radius (55%) fractures were the most commonly performed surgeries. Surgeons preferred full personal protection equipment kits (69%) with a respirator (N95/FFP3), but in the case of unavailability, they used surgical masks and normal gowns. Regional/local anesthesia (70%) remained their choice for surgery to prevent the aerosolized risk of contaminations. Essential surgical follow-up with limited persons and visits was encouraged by 70% of the surgeons, whereas teleconsultation and telerehabilitation by 30% of the surgeons. Despite the protective equipment, one-third of the surgeons were afraid of getting infected and 56% feared of infecting their near and dear ones. Orthopaedic surgeons in private practice did face 50 to 75% financial loss and have to furlough 25% staff and 50% paramedical persons. Orthopaedics meetings were cancelled, and virtual meetings have become the preferred mode of sharing the knowledge and experiences avoiding human contacts. Staying at home, reading, and writing manuscripts became more interesting and an interesting lifestyle change is seen among the surgeons. Unanimously and without any doubt all accepted the fact that COVID-19 pandemic has reached an unprecedented level where personal hygiene, hand washing, social distancing, and safe surgical practices are the viable antidotes, and they have all slowly integrated these practices into their lives. Strict adherence to local authority recommendations and guidelines, uniform and standardized norms for admission, inpatient, and discharge, mandatory RT-PCR tests before surgery and in selective cases with CT scan chest, optimizing and regularizing the surgeries, avoiding and delaying nonemergency surgeries and follow-up protocols, use of teleconsultations cautiously, and working in close association with the World Health Organization and national health care systems will provide a conducive and safe working environment for orthopaedic surgeons and their fraternity and also will prevent the resurgence of COVID-19., Competing Interests: NoteConflict of Interest The views expressed in this article are those of the authors and do not represent the official policy of the any country.

- Abstract
Arthroscopic surgery of the hip has evolved significantly over the last years, offering an opportunity of treatment in several intra-articular pathologies. Recent methods and instrumental advances have allowed more frequent use of this procedure, with various indications such as: hip pain, acetabular labrum lesions, extraction of foreign bodies, debridement in septic arthritis, pincer impingement, and some extra-articular injuries. Another intra-articular hip pathology that benefits from arthroscopic assistance could be found in the management of simple acetabular fractures. Therefore, this report presents the case of a patient with a posterior column fracture treated with an arthroscopic approach. Arthroscopic techniques for the fixation of intra-articular fractures offer the advantage of a direct visualization of the articular surface, which results in an anatomical reduction. In addition, arthroscopic techniques also present a benefit for intra-articular injuries such as the posterior labral lesion in this case. In simple fractures of the posterior acetabular column with minimum displacement, where percutaneous screw fixation is useful as a definitive fixation method, hip arthroscopy is useful for the reduction process and verifies the extra-articular screw trajectory.
