Traumatic high-grade cervical spinal dislocations are rare injuries, generally associated with severe neurological compromise. In particular, cervical spondyloptosis (>100% subluxation) is rarely reported. The object of our study is to present a case series describing presentation, management, and outcome in traumatic high-grade cervical spinal dislocations. ⋯ In this series, 26.7% of patients had improvement in their AIS grade postoperatively, and the majority of patients (60%) maintained their preoperative AIS grade. In 57% of patients placed in traction, reduction was possible. Likely due to the severity of these injuries, there was a high incidence of complications. However, review of patient outcomes reveals that these patients can have improvement of neurological function. We recommend aggressive reduction and surgical stabilization. Our preference is either a combined anterior-posterior approach or a posterior-only approach.

Comparative Study
A comparative analysis of online education resources for patients undergoing endoscopic transsphenoidal surgery.
Endoscopic transsphenoidal surgery has become the most commonly performed surgical procedure for pituitary tumor removal. As such, there are many patient-oriented educational materials on the technique available online for members of the public who desire to learn more about the surgery. It has been recommended that educational resources be written to the national average reading level, which in the United States is between sixth and seventh grade. This study assesses the reading level of the educational materials currently available online for endoscopic transsphenoidal surgery and determines whether these resources are written at a suitable comprehension level for most readers. ⋯ The online educational resources written for patients about endoscopic transsphenoidal surgery are above the recommended reading level for patient education materials. Further revisions to simplify these resources on endoscopic transsphenoidal surgery are needed to ensure that most patients can comprehend this important material and make informed decisions about their health care.

Validity of prognostic grading indices for brain metastasis patients undergoing repeat radiosurgery.
We tested the validity of 5 prognostic indices, Recursive Partitioning Analysis (RPA), Score Index for Radiosurgery (SIR), Basic Score for Brain Metastases (BSBM), Graded Prognostic Assessment (GPA), and Modified-RPA, for patients who underwent repeat stereotactic radiosurgery (re-SRS). ⋯ Among the 5 systems, based on patient number proportions, MST separation among the 3/4 groups, and/or detailed reflection of status changes, the Modified-RPA system was shown to be most applicable to re-SRS patients.

Pure intraventricular craniopharyngioma is a rare subtype of craniopharyngioma that attaches frequently to the hypothalamus. The main challenge in tumor removal is protection of hypothalamic structure. The aim of our study was to set up a feasible risk-evaluation approach to help the surgeons make an individual treatment plan. ⋯ Attachment and deformation grade evaluated based on our criteria are significantly correlated with postoperative outcome. GTR of tightly attached tumor is associated with worse endocrinologic, functional, and radiologic outcomes compared with STR. Hence, we suggest that individual surgical plans should be made according to the grade of tumor attachment and hypothalamic deformation. STR should used in tumors with a high grade to achieve a good long-term outcome and avoid severe postoperative sequelae.

The classic anatomic view of the course of the internal carotid artery (ICA) and its segments familiar to neurosurgeons by a 3-dimensional microscopic cranial view may be challenging to understand when seen in the unique 2-dimensional view of transnasal endoscopic surgery. ⋯ Our classification of the segments of the ICA achieves consistency without sacrificing either clinical or anatomic accuracy for either transcranial or endoscopic approaches. Universal application of this established nomenclature can avoid new and misleading terms, respects anatomical landmarks delineating segments, and provides a universal language for clear communication between disciplines.
