Objective: To present the first Brazilian real-world results with galcanezumab and provide a consensus expert opinion on the prophylactic treatment of cluster headache (CH) in Brazil.

Methods: The first part of the study (real-world results) was observational, prospective, uncontrolled, and descriptive. A sample of 44 consecutive patients with episodic or chronic CH were evaluated and treated in a traditional tertiary clinic from March 2020 to June 2024.

Effect of mechanical stability of osteosynthesis on infection rates: Timing of temporary and definitive fixation.

Fracture related infection (FRI) remains one of the most challenging complications of orthopaedic trauma surgery. Several factors contribute to FRI development but, among those, particularly interesting from the orthopaedic surgeon's perspective is the contribution of mechanical stability and timing of fracture fixation. These are indeed crucial factors both in prevention and treatment of FRI and are directly influenced by the surgeon's work.

Biofilm Formation, Antibiotic Resistance, and Infection (BARI): The Triangle of Death.

Fracture-related infection (FRI) is a devastating event, directly affecting fracture healing, impairing patient function, prolonging treatment, and increasing healthcare costs. Time plays a decisive role in prognosis, as biofilm maturation leads to the development of antibiotic resistance, potentially contributing to infection chronicity and increasing morbidity and mortality. Research exploring the association between biofilm maturation and antibiotic resistance in orthopaedics primarily addresses aspects related to quality of life and physical function; however, little exists on life-threatening conditions and mortality.

The current role of barbed sutures in fascial closure of ventral hernia repair: a multicenter study using the abdominal core health quality collaborative database.

Background: Barbed sutures (BS) have been increasingly used in the last two decades across surgical disciplines but little is known about how widespread their adoption has been in ventral hernia repair (VHR). The aim of this study was to document the use of barbed sutures in VHR in a multicenter database with associated clinical and patient-reported outcomes.

Method: Prospectively collected data from the Abdominal Core Health Quality Collaborative database was retrospectively reviewed, including all adult patients who underwent VHR with fascial closure from 2020 to 2022.

Trauma center rehabilitation systems in Latin America.

Trauma is a leading cause of mortality and morbidity worldwide with high rates of disability in survivors. With improvements in care, rehabilitation of the trauma patient is a cornerstone to reducing sequelae. A lack of well-established hospital rehabilitation units and standardized protocols for managing posttraumatic injuries is a common problem in Latin American countries.

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.

Doctor, When Should I Start Walking? Revisiting Postoperative Rehabilitation and Weight-Bearing Protocols in Operatively Treated Acetabular Fractures: A Systematic Review and Meta-Analysis.

: Management of acetabular fractures is aimed at anatomically reducing and fixing all displaced or unstable fractures, as the accuracy of fracture reduction has been demonstrated to strongly correlate with clinical outcomes. However, there is a noticeable gap in the literature concerning the perioperative and postoperative care of patients with acetabular fractures, which ultimately can be potential risk factors for adverse outcomes and permanent disabilities. This study aimed to systematically review the available literature regarding rehabilitation practices, including weight-bearing protocols, across time points in surgically treated acetabular fracture patients and correlate these practices with functional outcomes.

Modified-tension band suturing: 'the pulling the reins technique' - a technique for displaced proximal humeral fracture with medial column instability.

Fractures of the proximal humerus with medial column instability are challenging and present an unacceptable rate of complications and reoperations. Despite good results reported with the use of locking plates and augmentation techniques using bone graft or a second plate, varus subsidence and fixation failure have been frequently reported. We describe the case of a patient presenting with a complex, multifragmentary proximal humerus fractures successfully treated with open anatomic reduction and internal fixation using a locking plate augmented with lateral traction using three bone anchors in the humerus head.

Geriatric proximal femur fracture updates.

Proximal femur fractures in the aging population present a variety of challenges. Physiologically, patients incurring this fracture are typically frail, with significant medical comorbidities, yet require early surgical treatment to restore mobility to prevent deterioration. Socioeconomically, the occurrence of a fragility fracture may be the beginning of the loss of independence, and the burdens of rehabilitation and support are borne by the individual patient and health care systems.

Novel implant design for comminuted posterior wall acetabular fractures.

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.

LEADERSHIP DEVELOPMENT TRAINING FOR BRAZILIAN ORTHOPEDIC SURGEONS.

Objective: To report on the experience and impressions of the Brazilian orthopedic trauma surgeons attending the Leadership Development Program (LDP) hosted by the Sociedade Brasileira do Trauma Ortopédico (SBTO) in Sao Paulo, Brazil on November 4, 2022.

Methods: Forty-eight orthopedic trauma surgeons from five different regions throughout Brazil were provided a link to complete The Big Five Test, a validated online personality assessment. The questionnaire was available in Portuguese and was intended to provide a background on individual personality traits and their influence on interpersonal interactions.

Management of shunt dysfunction using noninvasive intracranial pressure waveform monitoring: illustrative case.

Background: Normal pressure hydrocephalus (NPH) treatment consists of using valves for drainage, as it is for hydrocephalus in general. Despite this, complications can occur, putting the patient at risk, and neurological monitoring is crucial.

Observations: A 61-year-old male, who had been diagnosed with NPH 3 years prior and was being treated with a ventriculoperitoneal shunt with a programmable valve, presented to the emergency department because of a traumatic brain injury due to a fall from standing height.

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.

Antegrade posterior column screw fixation for acetabular fractures: It's time to standardize the surgical technique.

Antegrade fixation of posterior column fractures of the acetabulum is challenging due to the narrow corridor and risk of screw misplacement. Although both antegrade and retrograde lag screws have been previously described for posterior column fracture fixation, the literature lacks a standardized technique for correct and safe screw placement, especially in an antegrade fashion. This technical note aims to optimize intraoperative images during posterior screw insertion using the antegrade technique, according to predetermined landmarks to save surgical time, decrease radiation exposition, and prevent surgical complications.

In vitro biomechanical analysis of a locking self-compression screw model applied to Pauwels III and comminuted femoral neck fractures.

Femoral neck fractures (FNFs) affect the young adult population and are intimately related to high-energy trauma. Despite innovations in osteosynthesis materials, the rate of complications remains at 10%-59% in Pauwels type III (PIII) fractures. The authors thus propose a fixation model with a novel self-compression screw, comparing it to a sliding hip screw plate associated with a derotation screw in the fixation of a PIII fracture with posterior inferior comminution.

Comparison of sacroiliac screw techniques for unstable sacroiliac joint disruptions: a finite element model analysis.

Vertically unstable pelvic injuries associated with sacroiliac disruption are challenging. Although percutaneous iliosacral fixation using two screws at S1 vertebral body has been shown beneficial, the use of two transiliac screws at S1 has been proposed to increase the fixation strength of the construct. In the herein study, the finite element method (FEM) was performed to analyse the biomechanical behaviour of five different constructions using iliosacral screws only, transiliac screws only, and combining an iliosacral and a transiliac screw.

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.

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.
