Background: Previous research on spinal alignment and postoperative outcomes after cervical and upper thoracic fixation has suggested that clinical and patient-reported outcomes are improved when certain anatomical parameters are maintained. These parameters include the cervical sagittal vertical axis (cSVA), C2 and T1 slopes, and cervical lordosis (CL). For patients with primary and metastatic tumors involving the subaxial cervical and/or upper thoracic spine, there is minimal guidance on how to apply these parameters.

Background: The authors report on a patient who presented with an extremely large presacral schwannoma and subsequent mass effect-induced hydronephrosis and kidney failure. To the authors' knowledge, this case represents the largest radiographically verified spinal schwannoma in the medical literature. The tumor presented here was more than three times as large as a typical giant schwannoma.

- The study investigates how social determinants of health (SDoH) like race, insurance, and income affect access to and outcomes of spine tumor surgeries, revealing disparities compared to intracranial tumor cases.
- Data from over 6 million spine tumor admissions from 2002 to 2019 were analyzed, focusing on how these SDoH correlate with surgical outcomes such as mortality, complications, and length of stay.
- Findings suggest non-White patients and those with nonprivate insurance faced lower chances of receiving surgery, worse presenting conditions, and poorer discharge outcomes, indicating significant health inequities in spine tumor treatment.
Article Synopsis
- The study investigates how neighborhood-level resource disadvantage, measured by the Area Deprivation Index (ADI), affects long-term outcomes after spine tumor surgery.
- Researchers analyzed data from 237 patients treated between 2015 and 2022, categorizing them into advantaged and disadvantaged based on their ADI scores.
- Results revealed that disadvantaged patients had worse functional status, higher ambulation deficits, and more frequent non-elective surgeries compared to their advantaged counterparts.
Background: Ultrasound imaging is inexpensive, portable, and widely available. The development of a real-time transcutaneous spinal cord perfusion monitoring system would allow more precise targeting of mean arterial pressure goals following acute spinal cord injury (SCI). There has been no prior demonstration of successful real-time cord perfusion monitoring in humans.
