To investigate the relationships between sagittal alignment parameters and Neck Disability Index (NDI) scores after adjacent 2-level anterior cervical diskectomy and fusion (ACDF) and to study the impact of the T1 slope (T1s) minus C2-7 lordosis (T1s-CL). ⋯ Changes in cervical sagittal parameters after 2-level ACDF were associated with quality of life. A greater T1S-CL mismatch was related to a greater degree of cervical malalignment. T1s-CL may be a more important predictor of cervical malalignment than C2-7 SVA. Specifically, a mismatch greater than 28.07 corresponded to positive cervical sagittal malalignment, defined as an NDI score greater than 25.

A meta-analysis of randomized controlled trials (RCTs) was performed to compare the incidence of cement leakage between unilateral and bilateral percutaneous vertebral augmentation (PVA) in treating osteoporotic vertebral compression fractures (OVCFs). ⋯ The results of our meta-analysis have provided sufficient evidence to show that the unilateral approach can decrease the incidence of cement leakage in PVA. We believe the unilateral approach could reduce the risk of cement leakage owing to the lower cement dosage in the treated vertebra.

Review Case Reports
Endovascular coil embolization with LVIS Jr. stent for ruptured dissecting aneurysm of proximal superior cerebellar artery - a case report and literature review.
Superior cerebellar artery (SCA) aneurysm arising from the SCA itself is rare, and treatment of this aneurysm is challenging because of the important anatomic structures, such as the perforating arteries to the brainstem and cranial nerves. We describe a successful coil embolization with a Low-profile Visualized Intraluminal Support Junior (LVIS Jr.) stent for the proximal SCA dissecting aneurysm. ⋯ Endovascular treatment assisted with LVIS Jr. stent for proximal SCA dissecting aneurysm arising from small parent artery was safely and effectively feasible.

Review Case Reports
Correlation Studies and Literature Review of Medullary Artery Occlusion after Intracranial Vertebral Artery Stenting.
Stenosis of the target intracranial vertebral artery is one of the major causes of posterior circulation ischemic stroke. The objective of this paper is to explore methods for reducing the occurrence of medullary artery occlusion after intracranial vertebral artery stenting. ⋯ Perforating artery occlusion after intracranial vertebral artery stenting can be prevented by strict assessment and preparation before surgery, correct choices of saccule and stent during operation, and other measures. However, large sample data are needed for verification.

Review Case Reports
Intracranial Dural Parafalcine Chondroma: Case report and systematic review of the literature.
Intracranial chondromas are rare, benign neoplasms representing only 0.2%-0.3% of neoplastic intracranial lesions. They commonly originate from the skull base but can infrequently arise from the falx, convexity dura, or ventricular ependyma. ⋯ We describe the case of a patient harboring a parafalcine dural chondroma that was discovered incidentally and was managed surgically at our institution. We also provide a systematic review of the literature to elucidate incidence, origin, imaging findings, surgical management approaches, and prognosis of this rare tumor.
