The current research on geriatric patients with spinal chondrosarcoma is limited. This study aimed to investigate the demographics, patterns of care, and survival of geriatric patients with chondrosarcoma of the mobile spine. ⋯ Surgical resection significantly lowered the mortality risk in geriatric patients with spinal chondrosarcomas. Demographic and geographical factors significantly dictated treatment plans. Further studies are required to assess the role of radiotherapy and chemotherapy in treating these patients in the modern era.

The time from onset to symptom deterioration in ischemic stroke often exceeds 24 hours, and this ultra-late time window is excluded from the endovascular treatment (EVT) guideline. This study aimed to explore the safety and efficacy of EVT in progressive acute ischemic stroke with large vessel occlusion (AIS-LVO) stroke patients with onset to symptom deterioration times of 24h-7 days. ⋯ For patients with progressive AIS-LVO in the ultra-late time window, EVT remains a viable treatment approach.

The prevalence of osteoporotic vertebral fractures has increased with aging populations, necessitating effective treatments such as percutaneous kyphoplasty combined with posterior screw fixation. However, biomechanical research on the effects of using short screws on fixation stability and bone stress or on the impact of bone cement bonding to screws on structural strength is lacking. This study aimed to optimize short-segment fixation strategies for osteoporotic thoracolumbar burst fractures by analyzing the biomechanical effects of pedicle screw length and bone-cement augmentation. ⋯ Short screws in injured vertebrae without contact with the bone cement can achieve satisfactory stability and stress distribution. It is feasible to implant short screws in the injured vertebrae, reduce the number of bilaterally injured vertebrae, and inject bone cement through the non-pedicle approach during the surgical procedure, which simplifies the surgical process.

Intraventricular hemorrhage (IVH) and germinal matrix hemorrhage (GMH) are the most common brain injuries in preterm infants. Neonates with these injuries are at greater risk of impaired neurodevelopmental outcome. Current guidelines recommend screening infants with cranial ultrasound (CUS); however, this is prone to missing subtle injury patterns, particularly within the posterior fossa. The present report sought to discuss the utility of diffusion tensor imaging (DTI) in preterm infants. ⋯ Although DTI is more sensitive for picking up subtle injury patterns, CUS remains the standard of care when screening for injuries that would necessitate surgical intervention. DTI offers a refined understanding of the sequelae of GMH-IVH with microstructural changes found on DTI being associated with childhood motor and cognitive outcomes.

This study aims to comprehend the natural history of adolescent idiopathic scoliosis (AIS) patients and determine risk factors for facet joint bridging in adolescent-onset adult idiopathic scoliosis with thoracolumbar/lumbar (TL/L) curves. ⋯ This research revealed that large SVA, the presence of vertebral bridging, and large AVR are associated with facet joint bridging in adolescent-onset adult idiopathic scoliosis patients with TL/L curves. The cutoff value for facet joint bridging based on SVA was 2.1 cm.
