A 72-year-old man presented to the emergency department with severe acute low back pain.

Medial augmentation of distal femur fractures using the contralateral distal femur locking plate: A technical note.

Introduction: Lateral locking plates are commonly employed for the fixation of distal femur fractures. However, scenarios involving medial comminution, extremely distal fractures, periprosthetic fractures, or nonunion could necessitate medial augmentation. This study explores the possibility of using lateral distal femoral locking plate systems for medial fixation by employing the contralateral plate.

This study aims to compare complications, clinical, and radiological outcomes between PA screws and posterior plate in PMF using current literature. A systematic search strategy was conducted following the PRISMA protocol.

The Perspective of Brazilian Women Orthopaedic Surgeons on Gender Discrimination: Initial Insights to Understand Gender Bias in the Brazilian Healthcare System.

Despite the societal progress made in recent years, gender discrimination is still common in healthcare, especially in some surgical specialties such as orthopaedics. In Brazil, where the participation of women in the medical profession has been increasing, little is known about women's perceptions on the issue of gender discrimination. This study aims to examine women orthopaedic surgeons' experiences in dealing with conflict in the workplace and contextualize the impact that gender discrimination has had or currently has on their careers and well-being.

This case report describes the management of a woman diagnosed with a retroperitoneal cystic tumor during pregnancy. The 29-year-old patient presented at 29 weeks of pregnancy with abdominal pain. A retroperitoneal tumor measuring 224 × 156 × 235 mm was identified on ultrasound and magnetic resonance imaging.

Navigated Anterior Full-Endoscopic Transcervical Approach Odontoidectomy for Traumatic Posterior Atlantoaxial Dislocation Without Odontoid Fracture.

Background And Importance: Complete posterior atlantoaxial dislocation (PAAD) with an unfractured odontoid process is a rare condition where a dislocated but intact odontoid process is positioned ventrally to the anterior arch of C1. This lesion is related to transverse and alar ligament rupture secondary to hyperextension and rotatory traumatic injury and is often associated with neurological deficit. The treatment strategy remains controversial, and in many cases, odontoidectomy is required.

Factors of poor prognosis in newborns with a prenatal diagnosis of gastroschisis in Bogota, Colombia.

Objectives: To identify factors associated with poor prognoses in newborns with a prenatal diagnosis of gastroschisis in eight hospitals in Bogota, Colombia, from 2011 to 2022.

Methods: A multi-center retrospective case-control study was conducted on newborns with gastroschisis in eight hospitals in Bogota, Colombia. Poor prognosis was defined as the presence of sepsis, intestinal complications, or death.

Prediction model for lower limb amputation in hospitalized diabetic foot patients using classification and regression trees.

Background: The decision to perform amputation of a limb in a patient with diabetic foot ulcer (DFU) is not an easy task. Prediction models aim to help the surgeon in decision making scenarios. Currently there are no prediction model to determine lower limb amputation during the first 30 days of hospitalization for patients with DFU.

Von Willebrand Disease and Pregnancy: Management Protocol From Labor to the Postpartum Period.

Von Willebrand disease (VWD) is a hemostatic disorder characterized by a quantitative or qualitative deficiency of the Von Willebrand factor (VWF). It affects males and females equally. This pathology has more severe clinical manifestations in females of reproductive age, with a mean age of diagnosis at 19 years.

Bullous Pemphigoid Associated With the Use of Sacubitril/Valsartan: A Case Report and Literature Review.

 Bullous pemphigoid (BP) is a complex autoimmune blistering disease with an increased incidence in the comorbid population, particularly among older adults. The occurrence of drug-induced BP is associated with an underlying genetic predisposition, triggering an enhanced immune response, the formation of autoantibodies, and alterations in antigenic properties within the basement membrane zone. With over 90 identified drugs capable of precipitating BP, we present the case of an 87-year-old woman with comorbidities who experienced a medication change from losartan to sacubitril/valsartan.

The Role of Trabecular, Ligamentous-Intervertebral Disk and Facet Joints Systems: A Finite Element Analysis in the L4-S1 Vertebrae.

Study Design: Descriptive.

Objectives: Trabecular bone in the vertebrae is critical for the distribution of load and stress throughout the neuroaxis, as well as the intervertebral disk, ligamentous complex, and facet joints. The objective was to assess the stress and strain distribution of the L4-S1 spine segment by a finite element analysis.

Advanced Surgical Techniques for Dural Venous Sinus Repair: A Comprehensive Literature Review.

The dural venous sinus (DVS) is a thin-walled blood channel composed of dura mater that is susceptible to injury during common neurosurgical approaches. DVS injuries are highly underreported, which is reflected by a lack of literature on the topic. Neurosurgeons should be familiar with appropriate techniques to successfully repair an injured DVS and prevent associated complications.

Ulnar nerve mononeuropathy in a patient with Hansen's disease: Clinical and radiological features.

Leprosy is a chronic infection caused by bacteria called . This is a prevalent disease in low-income countries, and it has not been completely eradicated. We present the case of a 29-year-old man with a previous diagnosis of Hansen's disease, who consulted for pain in the left elbow and wrist, associated with fever with preserved mobility and pain on palpation.

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.

Effectiveness of antibiotic-coated intramedullary nails for open tibia fracture infection prevention. A systematic review and meta-analysis.

Introduction: Open Tibia fractures are associated with high rates of Fracture Related Infection (FRI). Given the negative outcomes and increased costs related to the latter, several prophylactic local antibiotic delivery methods have been proposed, aiming to decrease the FRI rate. Our objective with this study was to determine the effectiveness of antibiotic-coated intramedullary nails for open tibia FRI prevention.

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.

Liquid biopsy in the setting of leptomeningeal metastases: a systematic review and meta-analysis.

Purpose: The blood-brain barrier can prevent circulating tumor DNA (ctDNA) derived from the central nervous system from entering the blood making it challenging to evaluate molecular features of leptomeningeal metastasis (LM). Accordingly, we sought to systematically compare the diagnostic power or significance of ctDNA derived from cerebrospinal fluid (CSF) compared to plasma ctDNA in patients with LM.

Methods: A systematic review and meta-analysis was performed under the PRISMA guideline.
