Efficacy and outcomes of rescue screws in unstable pelvic ring injuries - A retrospective matched cohort study.

Purpose: The emergency treatment of unstable pelvic ring injuries is still a challenge and requires surgical and anesthesiological resuscitation. Emergency fixation of the unstable pelvic ring with percutaneous sacroiliac (SI) screws, also known as "Rescue Screws", is an established treatment method. The aim of our study was to compare the outcome and complication rates of "Rescue Screws" with elective SI-screw fixations.

Can radiologic parameters used to detect cervical spinal instability be used in patients with ankylosing spondylitis?

Introduction: Cervical spinal instability can be difficult to detect in the shock room setting even with the utilization of computed tomography (CT) scans. This may be especially true in patients with cervical degenerative disease, such as ankylosing spondylitis (AS). The purpose of this study was to investigate the influence AS has on various radiologic parameters used to detect traumatic and degenerative instability of the cervical spine, to assess if CT imaging in the shock room is diagnostically appropriate in this patient population.

Effects of Occult Hypoperfusion on Local Circulation and Inflammation - An Analysis in a Standardized Polytrauma Model.

Introduction: Occult hypoperfusion (OH) is defined as persistent lactic acidosis despite normalization of vital parameters following trauma. The aim of this study was to analyze the association of occult hypoperfusion with local circulation and inflammation of injured soft tissue in a porcine polytrauma model.

Methods: This experimental study was performed with male landrace pigs who suffered a standardized polytrauma, including a femoral fracture, blunt chest trauma, liver laceration and a mean arterial pressure (MAP) controlled hemorrhagic shock.

Cellular activation status in femoral shaft fracture hematoma following different reaming techniques - A large animal model.

The local inflammatory impact of different reaming protocols in intramedullary nailing has been sparsely investigated. We examined the effect of different reaming protocols on fracture hematoma (FH) immunological characteristics in pigs. To do so, a standardized midshaft femur fracture was induced in adult male pigs.

Improved Clinical and Financial Outcomes in Proximal Gastric Bypass Surgery Following the Transition from a Conventional Circular Stapling to an Augmented Linear Stapling Protocol.

Unlabelled: Bariatric techniques for bypass surgery evolve constantly. Switching from one well-established protocol to another in a running surgical teaching program is challenging. We analyzed clinical and financial outcomes at a single bariatric center transitioning from circular to an augmented linear bypass protocol.

Splenectomy is associated with altered leukocyte kinetics after severe trauma.

Background: Inadequate activation of the innate immune system after trauma can lead to severe complications such as Acute Respiratory Distress Syndrome and Multiple Organ Dysfunction Syndrome. The spleen is thought to modulate the cellular immune system. Furthermore, splenectomy is associated with improved outcome in severely injured trauma patients.

Curiosity or Underdiagnosed? Injuries to Thoracolumbar Spine with Concomitant Trauma to Pancreas.

The pancreas is at risk of damage as a consequence of thoracolumbar spine injury. However, there are no studies providing prevalence data to support this assumption. Data from European hospitals documented in the TraumaRegister DGU (TR-DGU) between 2008-2017 were analyzed to estimate the prevalence of this correlation and to determine the impact on clinical outcome.

Nonunion After an Open Trimalleolar Ankle Fracture: An Extended Clinical Course and a Novel Approach to Tibio-Talo-Calcaneal Arthrodesis.

Nonunion in the setting of chronic osteomyelitis after severe open ankle fractures is a feared outcome with severe loss in patient quality of life. Tibio-talo-calcaneal arthrodesis is a good salvage treatment option in this difficult patient cohort. We report a case of chronic osteomyelitis with severe destruction of the ankle joint after failed fracture fixation of an open trimalleolar ankle fracture.

Altered cell surface receptor dynamics and circulatory occurrence of neutrophils in a small animal fracture model.

Introduction: Excessive activation of the immune response after femoral fractures and fracture fixation is potentially associated with the development of systemic and local complications, particularly in multiple trauma patients. A dysregulated function of neutrophils, the most prevailing immune cells in circulation, has been discussed as a central pathophysiological background for these unfavourable post-traumatic courses. Our aim was to investigate alterations in activity and functionality as expressed by the cell surface receptor dynamics of circulatory neutrophils after femoral fracture and intramedullary stabilization.

Lessons learned from the mechanisms of posttraumatic inflammation extrapolated to the inflammatory response in COVID-19: a review.

Up to 20% of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) patients develop severe inflammatory complications with diffuse pulmonary inflammation, reflecting acute respiratory distress syndrome (ARDS). A similar clinical profile occurs in severe trauma cases. This review compares pathophysiological and therapeutic principles of severely injured trauma patients and severe coronavirus disease 2019 (COVID-19).

Prevalence, injury-, and non-injury-related factors associated with anxiety and depression in polytrauma patients - A retrospective 20 year follow-up study.

Introduction: Survival rate after polytrauma increased over the past decades resulting in an increase of long-term complaints. These include physical and psychological impairments. The aim of this study was to describe the prevalence and risk factors for developing depression and anxiety more than twenty years after polytrauma.

Nonoperative management of splenic injury in closely monitored patients with reduced consciousness is safe and feasible.

Background: Treatment of blunt splenic injury has changed over the past decades. Nonoperative management (NOM) is the treatment of choice. Adequate patient selection is a prerequisite for successful NOM.

Principles and current concepts in the surgical treatment of fragility fractures in the elderly.

The constant rise in fragility fractures is proportional to the constant rise in life expectancy. Treatment of fragility fractures can be challenging because of severe fractures, poor bone quality, significant co-morbidities, and reduced mobility. However, new surgical techniques and implants have been developed that address these challenges and show improvement in overall patient outcomes.

Psychiatric outcome at least 20 years after trauma: A survey on the status of subjective general health and psychiatric symptoms with a focus on posttraumatic stress disorder.

Background: Information on long-term psychiatric sequelae after severe trauma is sparse. We therefore performed a survey addressing several symptoms related to posttraumatic stress disorder (PTSD) in patients who sustained multiple injuries more than 20 years after trauma.

Methods: Patients injured between January 1, 1973, and December 31, 1990, were contacted at least 20 years later.

Does the time of day in orthopedic trauma surgery affect mortality and complication rates?

Background: Orthopedic trauma surgery has multiple, both patient-based and surgeon-based risk factors. Evaluating and modifying certain patient safety factors could mitigate some of these risks. This study investigates the influence that the time of day of surgery has on mortality and complication rates.

Safety of selective nonoperative management for blunt splenic trauma: the impact of concomitant injuries.

Background: Nonoperative management for blunt splenic injury is the preferred treatment. To improve the outcome of selective nonoperative therapy, the current challenge is to identify factors that predict failure. Little is known about the impact of concomitant injury on outcome.

Single-level vertebral kyphoplasty is not associated with an increased risk of symptomatic secondary adjacent osteoporotic vertebral compression fractures: a matched case-control analysis.

Unlabelled: This matched case-control study compared the rate of symptomatic adjacent-level vertebral compression fractures (VCF) within 1 year in patients operatively treated with kyphoplasty to a control group of non-operatively treated VCFs. The adjacent-level fracture rate did not show a significant difference between groups.

Purpose: To compare the rate of new symptomatic adjacent-level fractures within 1 year after an isolated osteoporotic vertebral compression fracture (VCF) treated by either kyphoplasty or non-operative treatment.
