OBJECTIVES: Posterior cruciate ligament (PCL) injuries are relatively common injuries associated with athletic activities and high-energy trauma. Posterolateral corner (PLC) injuries frequently accompany injury to the PCL. Diagnosis can be challenging and requires a comprehensive history and physical examination. Patients frequently report vague, nonspecific symptoms and the mechanism of injury is often useful in localizing injured structures. Two of the more common mechanisms for PCL injury include a direct blow to the proximal anterior tibia with the knee flexed, as well as a significant knee hyperextension injury...

BACKGROUND: Thoracic injuries are a leading cause of death in polytrauma patients. Early diagnosis and treatment are of paramount importance. Whole-body computed tomography (WBCT) has largely replaced traditional imaging techniques such as conventional radiographs and focused computed tomography (CT) as diagnostic tools in severely injured patients. It is still unclear whether WBCT has led to higher rates of diagnosis of thoracic injuries and thus to a change in outcomes. METHODS: In a retrospective study based on the trauma registry of the German Trauma Society (TraumaRegister DGU(®)), we analysed data from 16,545 patients who underwent treatment in 59 hospitals between 2002 and 2012 (ISS ≥ 9)...

Conventional documentation of surgical procedures using only pre- and postoperative X-ray images and possibly a few intra-operative pictures does not allow secondary analysis of the technical performance in detail. In particular, the quality of the handling of tissues and surgical tools cannot be judged «post hoc», i.e. after the end of the surgical procedure. The invasiveness of the surgical act cannot yet be quantified. Surrogate invasiveness indices have therefore been developed. Furthermore, conventional documentation does not allow evaluation of the proper use of the C-arm both technically and with regard to fluoroscopy time...

Georges Limbert
The objective of this paper is to provide a review on some aspects of the mathematical and computational modelling of skin biophysics, with special focus on constitutive theories based on nonlinear continuum mechanics from elasticity, through anelasticity, including growth, to thermoelasticity. Microstructural and phenomenological approaches combining imaging techniques are also discussed. Finally, recent research applications on skin wrinkles will be presented to highlight the potential of physics-based modelling of skin in tackling global challenges such as ageing of the population and the associated skin degradation, diseases and traumas...

OBJECTIVE Blunt cerebrovascular injuries (BCVIs) following trauma carry risk for morbidity and mortality. Since patients with BCVI are often asymptomatic at presentation and neurological sequelae often occur within 72 hours, timely diagnosis is essential. Multidetector CT angiography (CTA) has been shown to be a noninvasive, cost-effective, reliable means of screening; however, the false-positive rate of CTA in diagnosing patients with BCVI represents a key drawback. Therefore, the authors assessed the role of DSA in the screening of BCVI when utilizing CTA as the initial screening modality...

Osteomyelitis of the cervical spine is an exceedingly rare lesion in pediatric practice and is caused by a variety of mechanisms. The authors present a case in which cervical osteomyelitis presented in a delayed manner after the patient experienced a stable cervical extension injury at the C4-5 level. On review of the original images, the authors noted a likely perforation in the retropharyngeal space. This case highlights the risk of retropharyngeal injury in cervical trauma, with the seldom-seen complication of osteomyelitis as a result...

CLINICAL/METHODICAL ISSUE: Muscular injuries represent the most common musculoskeletal lesions. Especially in professional athletes an imaging clarification is essential in order to define the exact location of the lesion, the affected muscles, the extent and degree of the injury as well as to define possible concomitant complications. The best possible therapy can be initiated and a necessary rest period for a low risk resumption of sporting activity can be individually specified. STANDARD RADIOLOGICAL METHODS/METHODICAL INNOVATIONS: Due to technical improvements, for example mobile devices and thus increased rapid availability as well as relative cost-effectiveness compared to other modalities, the imaging evaluation of muscle injury would nowadays be unthinkable without ultrasound...

HYPOTHESIS: To explore the results of a new slim modiolar electrode array (SMA) with respect to intracochlear placement and trauma evaluated by detailed radiologic imaging and histology. BACKGROUND: Hearing and structure preservation is the goal of cochlear implantation for advanced hearing outcomes. Currently, this is most consistently achieved with thin lateral wall electrodes. Modiolar electrodes are located nearer the modiolus and may provide some electrophysiological advantages, but have a greater tendency for causing insertion trauma...

The broad application of low-dose computed tomography screening has resulted in the detection of many more cases of early lung cancer than ever before in modern history. Recent advances in the management of early-stage non-small cell lung cancer have focused on making therapy less traumatic, enhancing recovery, and preserving lung function. In this review, we discuss several new modalities associated with minimally invasive surgery for lung cancer. Firstly, less lung parenchyma resection via sublobar resection has become an acceptable alternative to lobectomy in patients with tumors less than 2 cm in size or with poor cardiopulmonary reserve...

The spleen is one of the most frequently injured organs in blunt abdominal trauma. In the past decades, the treatment of patients with blunt splenic injury has shifted from operative to non-operative management. The knowledge of physiology and immunology of the spleen have been the main reasons to develop techniques for splenic salvage. The advances in high-resolution imaging techniques, as well as less invasive procedures, including angiography and angioembolization, have allowed a higher rate of success in the non-operative management...

The extrapleural space (EPS) is an anatomic space at the periphery of the chest that can be involved in a number of disease processes. This space lies between the inner surface of the ribs and the parietal pleura and contains adipose tissue, loose connective tissue, lymph nodes, vessels, endothoracic fascia, and the innermost intercostal muscle. It is often overlooked on cross-sectional imaging studies and almost invariably overlooked on conventional radiographic studies. At conventional radiography, the EPS occasionally can be seen when there is extrapleural fat proliferation, which might be confused with pleural thickening or pleural effusion...

Cardiac injury remains a rare occurrence even to the most experienced trauma surgeon. Despite this rarity, a physician receiving trauma patients with potential injury to the heart must be prepared to lead a rapid and precise assessment, request the relevant diagnostic imaging, and guide a surgical or observation based plan. A high index of suspicion of cardiac injury is vital to avoid missed injuries and preventable fatalities. Knowledge of the differences between blunt and penetrating cardiac trauma is crucial in managing these patients...

INTRODUCTION: We report a pure distraction injury of the upper thoracic spine and uncontrolled hyperthermia without an infectious cause. Quad fever appears in the first several weeks to months after a cervical or upper thoracic SCI and is characterized by an extreme elevation in body core temperature beyond 40 °C without an infectious cause. Discriminating between infectious and noninfectious causes is important, and a thorough clinical assessment is required. MATERIALS AND METHODS: A 52-year-old male visited the emergency room complaining of back pain with complete paralysis [American Spinal Injury Association (ASIA) A] of both lower extremities after a pedestrian-motor vehicle accident...
