A 59-year-old male was admitted to the emergency room with signs of heart failure. The echocardiogram showed an extensive apical infarction with large mobile thrombi in the left ventricle. Doppler examination demonstrated apical rotating flow. Despite adequate anticoagulant therapy, the patient suffered a massive right-sided cerebral infarction leading to right ventricular cerebral compression. The thrombogenic risk of apical rotating flow and the need for anticoagulation are discussed.

Background: Vertebral body tethering (VBT) has shown improvements in coronal and sagittal plane correction in adolescent idiopathic scoliosis (AIS) patients, but axial correction over time remains unexplored. Three-dimensional (3D) spine reconstruction was used to analyse correctional changes in all spinal planes post VBT surgery.
Case Description: AIS subjects who underwent thoracic VBT surgery with a minimum 2-year follow-up were assessed.

Purpose: Although idiopathic scoliosis is a common three-dimensional deformity, there is a lack of studies evaluating the associations between the aortic-vertebral distance (AVD) and spinal deformities in all planes. The study therefore aimed to evaluate how the coronal and sagittal curvature, vertebral rotation and aortic-vertebral angle (AVA) affect the AVD in idiopathic scoliosis.
Methods: The AVD, AVA, vertebral rotation and curve angles were measured on preoperative magnetic resonance imaging and radiographs in 46 patients who underwent posterior spinal fusion with pedicle screw instrumentation for idiopathic scoliosis Lenke types 1 and 2.

Study Design: A retrospective comparative study.
Purpose: To validate the hypothesis that a combination of multilevel Ponte osteotomy (PO) with intraoperative traction (IOT) results in a better correction than IOT alone in high-magnitude curves in adolescent idiopathic scoliosis (AIS) and does not possess an attributable risk of neurological injury.
Overview Of Literature: On a comprehensive review of the literature, the choice of technique adopted for curves between 65° and 100° remains controversial with no major consensus favoring one technique over the other.

(1) Background: External force orthopedics and the strengthening of paraspinal muscles through exercise are common orthopedic methods for adolescent scoliosis, yet the synergetic mechanism of the two in orthopedic correction remains unclear. (2) Methods: A three-dimensional finite element model of the scoliotic spine was established to accurately simulate the mechanical properties of tissues such as the spine, intervertebral discs, and ribs. By applying external forces in different directions to the scoliosis model, the orthopedic effects of these forces on scoliosis were analyzed.

: Apical extrusion of debris can affect the success of endodontic treatments, and the specific performance of certain retreatment systems has not been studied yet. Therefore, the aim of this in vitro study was to quantitatively assess the amount of apically extruded debris produced during retreatment procedures using three rotary NiTi retreatment systems in mature non-resorbed straight roots. : Thirty extracted permanent human teeth with single straight roots were selected.
