The primary outcome was one-year mortality, while secondary outcomes were local complications and healthcare burden-related outcomes (nursing facility utilization and hospital length of stay).

Availability and use of resources for emergency fracture care of pelvic trauma associated with haemorrhagic shock in Latin America: A cross-sectional study.

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.

The internal rotation traction radiograph does not improve the reliability in the AO classification system for pertrochanteric fractures. An inter- and intra-observer reliability assessment.

Introduction: The most universal method for classifying pertrochanteric fractures is the AO/OTA classification. These fractures are classified into different categories according to the features found in the anteroposterior radiograph of the hip. Anteroposterior radiograph of the hip with internal rotation traction can improve the characterization of the fracture.

Is there a trend towards semi-extended knee positioning during intramedullary tibial nailing in Latin America? A survey among 990 orthopaedic surgeons.

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.

Bisphosphonates and atypical femoral fractures: Is the location of the fracture associated with the time of consolidation?

Introduction: Bisphosphonates are commonly prescribed to mitigate the effects of osteoporosis, a condition associated with an increased risk of fracture. However, despite their success, there has been growing concern regarding the long-term use of bisphosphonates because of the increased risk of atypical subtrochanteric fractures of the femur (AFFs). The objective of this study was to describe a cohort of patients with AFFs and evaluate the risk of evolving to non-union, the time of consolidation associated with the location of the fracture, the time of use of the drug, and the implant involved in its treatment.

Patients with trochanteric hip fractures and pre-existing osteoarthritis can be treated with nailing osteosynthesis without significant decrease in functional status.

Purpose: Functional outcome in patients after trochanteric fracture fixation with pre-existing radiographic osteoarthritis (OA) is unclear. Analyzing their function and independence, before and after fracture, could optimize their treatment and decrease the socioeconomic burden in this particular group.

Methods: The influence of pre-existing radiographic hip OA on functional outcome was retrospectively analyzed with a cohort of patients undergoing proximal femoral nailing for trochanteric fracture.

Treatment of fracture-related infection in Latin America (FRILA). Proposal for a multicentre regional registry.

Postoperative bone infection is a severe complication in the treatment of fractures. The management of this pathology is challenging, but recent advances have been made to achieve standardization that can help diagnosis and decision-making. However, we are unaware of studies validating these models in Latin America.

Very early prescription of range of motion exercises in ankle fractures treated with ORIF does not increase the rate of complications and reoperations: A survival risk analysis.

Background: Ankle fractures are commonly treated with non-surgical or surgical (preferably ORIF) approaches based on fracture characteristics. The postoperative care regimens vary widely, and the impact of very early mobilization on complications and reoperation rates in ankle fractures treated with ORIF remains unclear.

Methods: A retrospective analysis was conducted on ankle fractures treated between January 2014 and November 2020.

Development, implementation and evaluation of a multinational FLS mentorship programme in Latin America.

Unlabelled: Realising the benefits of systematic secondary fracture prevention requires supporting local sites to get started and becoming effective. We here describe the development, implementation and impact of a regional fracture liaison service (FLS) mentorship programme in Latin America that led to 64 FLS getting started and coverage of 17,205 patients.

Introduction: Despite treatments and service models to deliver effective secondary fracture prevention, most patients are left untreated after a fragility fracture.

Outcomes, risk factors, and conversion rate in acetabular fractures in patients over 65 years of age. Analysis at a mean follow-up of 6 years.

Introduction: Acetabular fractures are devastating injuries that can affect patients of different ages, as well as being associated with high or low energy trauma. Conversion to total hip arthroplasty (THA) results in increased complication rates, resource use and costs compared to primary THA due to osteoarthritis. The aim of this paper is to describe a retrospective cohort of patients over 65 years of age who presented with an acetabular fracture and were treated with open reduction and internal fixation (ORIF).

Variation in Body Mass and Skeletal Muscle Indices in Head and Neck Cancer Patients Undergoing (Chemo)Radiotherapy and Nutritional Intervention.

The aim of this study was to analyze variation in body mass index (BMI) and skeletal muscle index (SMI) in head and neck squamous cell carcinoma (HNSCC) patients who underwent exclusive radiotherapy (RT) or concurrent chemo-radiotherapy (RT-CHT). We enrolled 73 HNSCC pts treated with definitive or post-operative RT (14 pts) or RT-CHT (59 pts). At the time of diagnosis (t0) and 3 months after treatment completion (t3), CT scans were retrieved to measure skeletal muscle at the level of the C3 vertebra.

The online course included: didactic lectures, small-group clinical case discussions, and panel case discussions.

Syndesmosis injury associated with high-energy tibial shaft fractures: Case series of a misdiagnosis rupture.

Introduction: Ankle syndesmosis injuries can be associated with a spiral mechanism on tibial shaft fractures. We are not aware if there is evidence of the incidence of ipsilateral syndesmotic lesson associated to high-energy tibial shaft fracture mechanisms. The aim of this study was to analyze the incidence of syndesmotic injuries associated with high-energy tibial shaft fractures.

[Intramedullary nail for the surgical treatment of unstable fractures of the femur in previously amputated patients].

Introduction: Femoral fractures in previously amputated patients (PAP) have been poorly reported in international literature, however it is worth mentioning that advances in the manufacture of orthotics for lower limbs have allowed these patients to remain functionally active. Surgery is then an option but difficulties may appear in positioning the patient for surgery due to the absence of the foot or ankle from where to pull and optimize the fracture reduction.

Objective: We report 3 cases of PAP with ipsilateral unstable femur fractures, treated surgically with cervicodiaphyseal endomedular nail.

Impact of anticoagulants in elderly patients who suffer a hip fracture. Should we have a different approach?

Introduction: Hip fracture in the elderly is a frequent problem. Chronic treatment with anticoagulants is common in these patients, and may delay surgery.

Objectives: To compare time to surgery, hospital stay, in-hospital and 90 days complications between anticoagulated (A) and non-anticoagulated (NA) groups.

A Survivor-Derived Approach to Addressing Trafficking in the Pediatric ED.

Objectives: Our objective was to elicit the perspectives of survivors of child trafficking on addressing trafficking in the pediatric emergency department (ED) and, secondarily, to provide a survivor-derived framework to help pediatric emergency medicine (PEM) providers discuss trafficking with their patients.

Methods: We conducted in-depth, semistructured interviews with young adults who experienced trafficking as children and/or as adolescents. In the interviews, we employed a novel video-elicitation method designed by the research team to elicit detailed participant feedback and recommendations on the pediatric ED through an interactive, immersive discussion with the interviewer.

[Effect of nutritional status on mortality and functional recovery in older adults with hip fracture].

Introduction: Malnutrition is a common problem in the elderly population but has not been fully studied in elderly people with hip fractures. The goal is to estimate annual mortality based on nutrition in the elderly with hip fracture and compare motor functionality.

Material And Methods: Retrospective cohort of patients over 65 years of age with hip fracture included in the Institutional Register of The Elderly with Hip Fracture of a University Hospital, between July 2014 and July 2018.

A novel radiological projection of the pelvis to evaluate the sitting imbalance in pelvis nonunions and malunions.

Introduction: Inadequate initial management of unstable pelvic injuries is usually associated with a fracture non-union and/or mal-union. Complete clinical and imaging evaluation is mandatory for a correct preoperative planning. Among other symptoms, sitting discomfort may arise from asymmetry of the ischial tuberosities or pressure from a prominent bony projection.
