BACKGROUND CONTEXT: Cervical sagittal vertical axis (cSVA) of ≥40mm is recognized as the key factor of poor health-related quality of life, poor surgical outcomes, and correction loss after surgery for cervical deformity. However, little is known about the radiological characteristics of patients with cSVA≥40mm. PURPOSE: The purpose of this study was to identify the radiological characteristics of patients with cervical imbalance. DESIGN: Retrospective analysis of weight-bearing cervical magnetic resonance (MR) images PATIENT SAMPLE: Consecutive 1,500 MR images of symptomatic patients in weight-bearing position OUTCOME MEASURES: cSVA, cervical alignment, cervical balance parameters (T1 slope, Co-C2 angle, C2-C7 angle, C7-T1 angle, neck tilt and thoracic inlet angle), disc degeneration (Pfirmann and Suzuki classification), endplate degeneration (Modic change), Spondylolisthesis (antero- and retrolisthesis), antero-posterior (AP) diameter of dural sac, cross-sectional area (CSA) and fat infiltration ratio of the transversospinalis muscles at C4 and C7 levels METHODS: Patients were divided into two groups: cervical sagittal vertical axis (cSVA) ≥40mm and <40mm...

Fusion of the lumbosacral spine is a common surgical procedure to address a range of spinal pathologies. Fixation in lumbar fusion has traditionally been performed using pedicle screw (PS) augmentation. However, an alternative method of screw insertion via cortical bone trajectory (CBT) has been advocated as a less invasive approach which improves initial fixation and reduces neurovascular injury. There is a paucity of robust clinical evidence to support these claims, particularly in comparison to traditional pedicle screws...

Background: Fractures of the proximal part of the humerus represent almost 4-5% of all fractures. The rate of non union is estimated to be 1.1 to 10%. Non union, displacement, and fixation failure can be hazardous complications for these injuries. The purpose of our study was to evaluate the outcomes of plate and bone strut allograft with bone chips grafting augmentation in the management of proximal humeral aseptic non union. Methods: We treated 16 aseptic non union proximal humeral fractures by the medial humeral shaft bone strut allograft and lateral plate and screws with bone chips grafting...

BACKGROUND We aimed to evaluate the clinical and radiologic outcomes of using Sonoma WRx versus Micronail intramedullary nailing for the fixation of distal radius fractures. MATERIAL AND METHODS A total of 68 patients with primarily extra-articular and simple intra-articular fractures of the distal radius who underwent intramedullary distal radius fixation using Sonoma WRx (n=39) or Micronail (n=29) intramedullary nails were enrolled in the study. The clinical outcome measures included the range of motion (ROM), visual analog scale (VAS), functional outcomes (patient-reported Disabilities of the Arm, Shoulder and Hand [DASH] score and clinician-based Gartland-Werley score), radiographic scores (Stewart score), and parameters related to the quality of radiographic reduction and complications (radial inclination, volar tilt, radial height, and radio-ulnar variance)...

INTRODUCTION: The talus is the second largest bone of the foot. It is fundamental to ensure normal ankle-foot movements as it connects the leg and the foot. Talar fractures are usually due to high energy traumas (road accidents, high level falls). They are not common as they account for 3-5% of ankle and foot fractures and 0.85% of all body fractures. However, talar fractures not correctly diagnosed and treated can lead to avascular necrosis of the astragalus, pseudoarthrosis, early osteoarthrisis and ankle instability, declining the quality of life of patients...

Nosocomial pneumonia (HAP) is a frequent complication of hospital care. Most data are available on ventilator-associated pneumonia. However, infections on general wards are increasing. A central issue are infections with multidrug resistant (MDR) pathogens which are difficult to treat in the empirical setting potentially leading to inappropriate use of antimicrobial therapy.This guideline update was compiled by an interdisciplinary group on the basis of a systematic literature review. Recommendations are made according to GRADE giving guidance for the diagnosis and treatment of HAP on the basis of quality of evidence and benefit/risk ratio...

INTRODUCTION: The most common surgical treatment of traumatic spine fractures is through a posterior approach using pedicle screws and rods. Postoperative treatment protocols including the use of postoperative orthoses however differ between hospitals and surgeons. A three-point hyperextension orthosis is designed to support proper posture and unload the anterior column. Some motion remains when wearing an orthosis, and its main value in postoperative treatment is therefore believed to be pain relief and patient confidence...

Describing complex mammography examination processes is important for improving the quality of mammograms. It is often difficult for experienced radiologic technologists to explain the process because their techniques depend on their experience and intuition. In our previous study, we analyzed the process using a new bottom-up hierarchical task analysis and identified key components of the process. Leveraging the results of the previous study, the purpose of this study was to construct a mammographic examination process ontology to formally describe the relationships between the process and image evaluation criteria to improve the quality of mammograms...
