Morbid obesity is associated with outcomes in patients undergoing vertebroplasty or kyphoplasty for osteoporotic vertebral compression fractures: a nationwide inpatient sample analysis.

Background: Osteoporotic vertebral compression fractures (OVCF) significantly affect older adults, leading to considerable morbidity and healthcare costs. Despite the known health risks of morbid obesity, its impact on surgical outcomes of OVCF remains underexplored. This study examines the influence of morbid obesity on the clinical outcomes of patients undergoing vertebral augmentation procedures, specifically vertebroplasty (VP) or kyphoplasty (KP).

An improvement of current hypercube pooling PCR tests for SARS-CoV-2 detection.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic can be effectively controlled by rapid and accurate identification of SARS-CoV-2-infected cases through large-scale screening. Hypercube pooling polymerase chain reaction (PCR) is frequently used as a pooling technique because of its high speed and efficiency. We attempted to implement the hypercube pooling strategy and found it had a large quantization effect.

Anti-Inflammatory Effects of Adenine Enhance Osteogenesis in the Osteoblast-Like MG-63 Cells.

Background: Adenine is a purine with a role in cellular respiration and protein synthesis. It is considered for its pharmacological potential. We investigated whether anti-inflammatory effect of adenine benefits on the proliferation and maturation of osteoblastic cells.

Geometrical analysis for assessing torsional alignment of humerus.

Background: Compared to other types of surgeries, minimally invasive surgeries (MISs) of humeral shaft fractures are associated with less radial nerve injury, less soft tissue injury and higher union rate. However, malrotation often occurs in MISs when closed reduction methods are used. This study aims to define specific palpable landmarks to help surgeons determine the correct torsional angle and reduce the incidence of malrotation.

Fat distribution may predict intra- or extra-capsular hip fracture in geriatric patients after falling.

Introduction: Hip fractures can be divided into intra-capsular and extra-capsular fracture based on fracture location; these two types of fracture have different pathogeneses, treatments and prognoses. Many factors influence the patterns of hip fractures, including the injury mechanism, areal bone mineral density and the geometry of the hip. However, the relationship between body composition and hip fracture pattern has not yet been discussed.

Incomplete insertion of pedicle screws in a standard construct reduces the fatigue life: A biomechanical analysis.

Pedicle screws are commonly used for posterior stabilization of the spine. When used in deformed or degenerated segments, the pedicle screws are often not fully inserted into the bone, but instead the threaded portion is exposed by 1 or 2 threads to accommodate rod placement and ensure alignment between the tulip of the screw and the rod. However, broken pedicle screws have been reported with the use of this method.
