Pelvic incidence minus lumbar lordosis mismatch (PI-LL) is directly related to poor quality of life in adult degenerative scoliosis (ADS) patients. The purpose of the study was to determine the most appropriate postoperative PI-LL value for patients with ADS. ⋯ Optimal PI-LL value should be 10°-20° after corrective surgery in patients with ADS, which is associated with excellent clinical outcomes and lower complication rates. Previous criteria may be at risk of overcorrection, which may lead to proximal junctional kyphosis.

Tectal plate tumors are a rare subset of midbrain tumors in pediatric populations. They are slow growing and low grade, with indolent and subtle manifestation unless they cause hydrocephalus.1-5 We present a tectal tumor in an 8-year-old girl (Video 1). Her clinical onset occurred with headache, vomiting, and seizure secondary to intracranial hypertension. ⋯ When this approach is selected, the venous anatomy must be navigated with caution. Angiography's venous phase may provide additional planning information.6 Coagulation of vascular structures such as occipital veins is carefully avoided since it creates risk of venous infarction, leading to visual loss. Histologic examination revealed a rosette-forming glioneuronal tumor (grade I WHO 20217).

Survival Factors in 1,580 Adults with Spinal Ependymoma: Insights from a Multi-Center Oncology Database.
Using a multi-institutional oncology database, we investigate the survival rates and the impacts of demographic, clinical, and management characteristics on overall survival among adult patients diagnosed with spinal ependymoma. ⋯ Early diagnosis and surgical management of spinal ependymomas, such as GTR, were associated with remarkable survival benefits. Old age, high-grade spinal ependymoma, and extra-neural metastasis were associated with worse overall survival, whereas radiotherapy's role remains unclear.

How maximal safe resection of glioblastoma (GBM) is implemented in the clinical setting remains understudied. Here, we utilized a survey-based approach to understand physician perspectives on this matter. ⋯ Our results suggest that while maximal safe resection remains a guiding principle for GBM resection, physician preference in terms of the extent of resection varies significantly as a function of tumor location and personal values.

To investigate the improvement of spinopelvic parameters and therapeutic efficacy in the treatment of complex degenerative lumbar spondylolisthesis (CDLS) after oblique lumbar interbody fusion (OLIF) and transforaminal lumbar interbody fusion (TLIF). ⋯ In the therapy of CDLS, OLIF can better reduce pelvic tilt, L1 axis S1 distance, and sagittal vertical axis, and increase lumbar lordosis angle and sacral slope, showing advantages over TLIF in improving and maintaining spinopelvic parameters. Although there was no difference in complication rates between OLIF and TLIF, OLIF was more minimally invasive, had less tissue damage, had faster recovery, and had better long-term outcomes.
