To put forward a new index of cervical curvature evaluation - relative cervical curvature area, and a new classification of cervical spine was proposed according to the relative cervical curvature area. ⋯ The relative cervical curvature area uses the area parameter instead of the original angle parameter and distance parameter to incorporate the change of segmental curvature, which makes up for the shortcomings of the Cobb angle method that only evaluates the curvature of 2 vertebrae, and better reflects the cervical curvature. Studies have shown that relative cervical curvature area has good repeatability and diagnostic value, and found that it has a good correlation with common cervical sagittal parameters. The new classification of cervical spine makes up for the disadvantage that the angle classification method cannot distinguish between S-type and RS-type, and initially proposes to use the number of intersections and the relative absolute value area to reflect the severity of S-type.

Meningiomas involving the dural venous sinuses present unique therapeutic challenges. While gross total resection remains the mainstay of treatment for meningiomas, involvement of critical vascular structures may limit extent of resection and increase the risk of recurrence. Optimal management of meningiomas with venous sinus involvement has been discussed in the literature, with some advocating for subtotal resection with postoperative surveillance and radiation, if necessary, while others recommend total resection with reconstruction of resection of the involved sinus. ⋯ Maximal safe resection, including resection and reconstruction of involved sinuses, may be a safe and effective treatment for many patients. Careful preoperative assessment of venous anatomy and planning extent of resection and reconstruction are essential for safe and successful surgery in these patients.

As value-based care grows in popularity across the United States, more payers have turned toward bundled payment models for surgical procedures. Though episode costs in spine are highly variable, physical therapy (PT) has been identified as a driver of 90-day cost. The goal of this study is to assess the impact of postoperative PT on patient-reported outcomes and cost after lumbar fusion surgery using bundled insurance data. ⋯ Our study finds that PT after lumbar fusion is not associated with significant improvement in Oswestry Disability Index, PCS, mental component score, or visual analog scale pain scores. Additionally, the number of PT sessions a patient attends has no correlation with improvement in these outcomes.

Advancing Neurosurgical Skills: A Comparative Study of Training Models for Intra-Extracranial Cerebral Bypass.
Training in anastomosis is fundamental in neurosurgery due to the precision and dexterity required. Biological models, although realistic, present limitations such as availability, ethical concerns, and the risk of biological contamination. Synthetic models, on the other hand, offer durability and standardized conditions, although they sometimes lack anatomical realism. This study aims to evaluate and compare the efficiency of anastomosis training models in the intra-extracranial cerebral bypass procedure, identifying those characteristics that enhance optimal microsurgical skill development and participant experience. ⋯ The study identifies the human placenta and UpSurgeOn models as optimal for training in intra-extracranial bypass procedures, emphasizing the need for diverse and effective training models in neurosurgery.
