Spinal chordomas are primary bone tumors where surgery remains the primary treatment. However, their low incidence, lack of evidence, and late disease presentation make them challenging to manage. Here, we report the postoperative outcomes of a large cohort of patients after surgical resection, investigate predictors for overall survival (OS) and local recurrence-free survival (LRFS) times, and trend functional outcomes over multiple time periods. ⋯ Surgeons must often weigh the pros and cons of en bloc resection and sacrificing important but affected native tissues. Our findings can provide a benchmark for counseling patients with spinal chordoma. Tumors ≥100 cm 3 appear to have a 5.89-times higher risk of recurrence, mobile spine chordomas have a 7.73 times higher risk, and neoadjuvant radiotherapy confers an 11.1 times lower risk for local recurrence. Patients age ≥65 years at surgery have a 16.70 times higher risk of mortality than those <65 years.

Multicenter Study
Reconstructive Endovascular Treatment of Compensative-Flow-Related Posterior Circulation Aneurysms With Anterior Circulation Artery Occlusion.
The aim of this study was to delineate the reconstructive endovascular treatment and periprocedural management of compensative-flow-related posterior circulation aneurysms with anterior circulation artery occlusion. ⋯ Our study indicates that reconstructive endovascular treatments are feasible and effective strategies for compensative-flow-related posterior circulation aneurysms with anterior circulation artery occlusion. However, these treatments are associated with a risk of periprocedural ischemic complications, which can be reduced by collateral arterial assessment, appropriate periprocedural anesthesia management, and antiplatelet treatment.

Image guidance has transformed minimally invasive spine surgery (MISS), allowing for safer procedures without excessive bony exposure and reducing radiation exposure for the surgical team. Robotic platforms have enhanced the benefits of navigation by providing high precision and accuracy. Here we describe a case series to demonstrate the accuracy and low complication rates of real-time image-guided robotic-assisted (RA) MISS at a tertiary referral center. In addition, we performed a narrative review on how robotics and navigation facilitate MISS. ⋯ Robotic platforms have further enhanced navigation benefits by providing high precision and accuracy, with low complication rates.

Single-position prone transpsoas (PTP) lateral interbody fusion has been proposed as an alternative to lateral lumbar interbody fusion performed in the lateral decubitus position. The advantages to this single-position technique include facilitating segmental lordosis, obviating the need for repositioning for posterior instrumentation, and providing access for posterior decompression. ⋯ This review provides a detailed technical description of the PTP technique at L4-L5. In addition, we provide technical pearls aimed at improving surgical ergonomics, workflow, and safety.

Tobacco use is known to affect incidence and postoperative outcome for several neurosurgical disorders, but its relationship to trigeminal neuralgia (TN) is not known. We sought to identify unique population characteristics that correlate with tobacco use in a cohort of patients with TN who underwent microvascular decompression (MVD), including effect on long-term postoperative outcome. ⋯ In patients undergoing MVD for TN, smoking is associated with younger age of TN onset, more widespread facial pain, and worse long-term postoperative outcome after MVD. These features suggest that TN in smokers may represent a more severe disease form compared with TN in nonsmokers with different responses to treatment.
