Extracranial vertebral artery aneurysms are extremely rare and are usually associated with trauma or dissection. Primary extracranial vertebral artery aneurysms are far less common. ⋯ Angiography remains the criterion standard in diagnosis and characterization of these lesions. We hereby present a case of a primary aneurysm of the extracranial portion of the vertebral artery and its surgical management, which implied an initial endovascular approach followed by a 2-step surgery to resect the aneurysm and stabilize the spine.

To evaluate the preliminary outcomes and clinical efficacy of a novel posterior biportal endoscopic technique in the treatment of central cervical disc herniation (CCDH). ⋯ The novel posterior biportal endoscopic technique demonstrated significant clinical efficacy and safety in treating CCDH, with marked improvements in clinical outcomes, rapid postoperative recovery, and a low incidence of complications.

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.

Non-opacification of frontal and parietal branches after MMA embolization: A radiographic benchmark.
Middle meningeal artery embolization (MMAE) has revolutionized the armamentarium for chronic subdural hematoma (CSDH) treatment. Technical and angiographic benchmarks to guide procedural and clinical success are less well established. ⋯ MMAE with nonopacification of F/P branches was associated with augmented efficacy. Nuanced MMAE adequately tackling culprit dural feeders should be considered for more effective procedures.

To analyze the clinical efficacy of ultrasonic bone scalpel (UBS)-assisted unilateral biportal endoscopic lamina osteotomy replantation (ULOR) for treating lumbar infectious spondylitis (LIS). ⋯ The use of ULOR with assistance from UBS for the treatment of LIS has proven to be beneficial. It provides significant relief from symptoms and corrects lumbar deformity. This surgical procedure is both effective and safe.
