5, P < 0.01; postoperative day [POD] 0 median pain score 2.5 vs. 4, P < 0.01; POD 0 mean opioid in mg 14.49 vs. 24.43, P < 0.01). The time until patients requested opioids for pain after surgery was prolonged for RA versus GA [mean 7.23 vs. 3.42 hours, P < 0.01). Somnolence (RASS < 0) on POD 0 was significantly reduced among RA versus GA, with 23% versus 43%. Both cohorts had equivocal postsurgical outcomes such as seizures, KPS, and hospital LOS.

Frontotemporal craniotomy under RA during awake craniotomies provides better pain control, a reduction in opioid use, and less somnolence in the early postoperative period.

To report our experience using the scan-and-plan workflow and review current literature on surgical efficiency, safety, and accuracy of next-generation robot-assisted (RA) spine surgery.

The records of patients who underwent RA pedicle screw fixation were reviewed. The accuracy of pedicle screw placement was determined based on the Ravi classification system. To evaluate workflow efficiency, 3 demographically matched cohorts were created to analyze differences in time per screw placement (defined as operating room [OR] time divided by number of screws placed). Group A had <4 screws placed, Group B had 4 screws placed, and Group C had >4 screws placed. Intraoperative errors and postoperative complications were collected to elucidate safety.

Eighty-four RA cases (306 pedicle screws) were included for analysis. selleck inhibitor The mean number of screws placed was 2.1 ± 0.3 in Group A and 6.4 ± 1.2 in Group C; 4 screws were placed in Group B patients. The accuracy rate (Ravi grade I) was 98.4%. Screw placement time was significantly longer in Group A (101 ± 37.7 minutes) than Group B (50.5 ± 25.4 minutes) or C (43.6 ± 14.7 minutes). There were no intraoperative complications, robot failures, or in-hospital complications requiring a return to the OR.

The scan-and-plan workflow allowed for a high degree of accuracy. It was a safe method that provided a smooth and efficient OR workflow without registration errors or robotic failures. After the placement of 4 pedicle screws, the per-screw time remained constant. Further studies regarding efficiency and utility in multilevel procedures are necessary.

Long-term outcomes for pediatric patients treated for spinal ependymoma are unknown.

We performed a retrospective analysis of outcome data from 33 children and young adults (0-22 years) who were operated on for a spinal ependymoma at our institution during the last 8 decades (1938-2019).

Nineteen patients are alive, with follow-up period up to 60 years. Twelve of them are tumor-free, and 7 are alive with disease. Fourteen patients are dead, 9 of them due to recurrent and/or progressive disease 1-56 years (median 11 years) after the initial surgery. Four of the deceased patients were treated before 1948, 3 of them with excellent long-term survival for 62-66 years after the initial surgery. Tumor recurrence was observed in half of the patients, both local at the site of the primary tumor resection as well as widespread intraspinal presentations. Recurrences were observed within months but also occurred after up to 20 years after initial treatment. After the implementation of magnetic resonance imaging in 1987, details of recurrent disease became more easily demonstrated. Repeated resections were performed when the symptomatic spinal disease was in progress (n= 11). Furthermore, 2 patients have intracranial tumor manifestations, 1 of them underwent resection of a suprasellar tumor in 1991. Four deceased patients experienced aggressive extraspinal progressive disease requiring multiple surgeries, including pulmonary metastasis in 1 of them.

Pediatric spinal ependymomas can be treated with favorable results and functional outcome may be good even after more than half a century of follow-up. Nevertheless, unexpected and late recurrences may occur, and life-long follow-up is therefore recommended.

Degenerative lumber spondylolisthesis (DLS) is a common orthopedic condition, described as a condition that compared with the lower vertebra, the superior vertebra slides forward or backward in the sagittal plane without accompanying isthmic spondylolisthesis. Information pertaining to different types of double-level DLS is scarce. This study aims to analyze parameters of patients with different types of double-level DLS to provide a reference for guiding surgical treatment and restoring sagittal balance of patients with DLS.

From January 2014 to January 2020, records of patients with double-level DLS were retrospectively reviewed. Patients with double-level DLS were divided into 3 types anterior, posterior, and combined; the anterior and combined types were studied. The sagittal spinopelvic parameters included C7 tilt, maximal thoracic kyphosis, maximal lumbar lordosis (LLmax), pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS). After descriptive analysis, demographic and radiographic data wents with double-level DLS, the sagittal spinopelvic parameters differed between the anterior and combined types. Overall, spinal surgeons should focus on correcting sagittal deformities, relieving postoperative clinical symptoms, and improving quality of life during fusion surgery.

Venous thromboembolism (VTE) is a significant contributor to postoperative morbidity and mortality. Prophylactic regimens for VTE involve mechanical prophylaxis and pharmacoprophylaxis. This systematic review and meta-analysis aimed to determine the efficacy and safety of pharmacoprophylaxis in comparison with any nonpharmacoprophylaxis regimen for the prevention of postoperative VTE in patients undergoing spinal surgery.

MEDLINE, Embase, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and ICRCTN were searched for comparative studies including both pharmacoprophylaxis and nonpharmacoprophylaxis post spinal surgery. The primary outcome was the incidence of VTE within the postoperative hospitalized period. Secondary outcomes included the incidence of spinal epidural hematoma, significant bleeding events, and other adverse events associated with VTE. The data was pooled using random-effects models of meta-analysis and relative risk (RR) was calculated.

Four retrospective and 3 randomize venous thrombosis. However, there is a need for future randomized controlled trials to investigate the efficacy and safety of pharmacoprophylaxis in spinal surgery across various spinal procedures.
To investigate the impact of race on 30-day postoperative complication rates of elective posterior spinal fusions (PSF) for adolescent idiopathic scoliosis (AIS).

Patients who underwent PSF between 2012 and 2018 were reviewed from the American College of Surgeons National Surgical Quality Improvement Program pediatric database. Propensity score matching was utilized to evaluate whether patient race (i.e., black vs. white) was correlated with postoperative complications.

A total of 4051 PSF for AIS cases met criteria for inclusion. Of these, 3221 (79.5%) patients were white and 830 (20.5%) were black. Several baseline characteristics significantly differed between cohorts. Patients in the black cohort had a significantly higher body mass index, a greater proportion of female patients, higher ASA scores, preoperative diagnosis of asthma or cardiac risk factors, and prior use of steroids. The total number of vertebral segments fused was also greater in the black cohort. After controlling for differences in study suggest that previously reported perioperative morbidity and mortality outcomes in black patients may be secondary to baseline health characteristics, and not due to race itself.
Acute spinal cord injury (ASCI) is a devastating event that can have a profound impact on the lives of patients and their families. While no definitive medical treatment exists, the role of methylprednisolone (MP) in the management of ASCI and other spinal cord pathologies has been investigated in depth; however, its use remains contentious. While MP initially showed promise in the efficacy of ASCI treatment, more recent studies have questioned its use citing numerous systemic adverse effects. Pharmacologic treatments in this area are poorly understood due to the scarcity of knowledge surrounding the pathophysiology and heterogeneity of patients presenting with these conditions. Despite these shortcomings and due to the lack of alternative treatment options, MP is still widely used by physicians.

We review prior and current literature on the use of MP treatment for ASCI patients with a discussion of novel drug delivery systems that have demonstrated the potential to improve MP's bioavailability at the site of injury while minimizing systemic side effects. In addition, current views on the role of MP and dexamethasone in metastatic spinal cord compression and postoperative infection are reviewed.

While some data support benefits in the use of steroids on spinal cord pathology, extensive research suggests at best limited effects and an unresolvable risk/benefit problem.

At present, evidence regarding use of dexamethasone for MSCC is contentious, especially regarding dose regiments. Ultimately, further investigation into the use of steroids is required to determine its utility in treating patients with spinal cord pathology.

Immediate and accurate detection of intracranial hemorrhages (ICHs) is essential to provide a good clinical outcome for patients with ICH. Artificial intelligence has the potential to provide this, but the assessment of these methods needs to be investigated in depth. This study aimed to assess the ability of Canon's
Stroke Solution ICH detection algorithm to accurately identify patients both with and without ICHs present.

Data from 200 ICH and 102 non-ICH patients who presented with stroke-like symptoms between August 2016 and December 2019 were collected retrospectively. Patients with ICH had at least one of the following hemorrhage types intraparenchymal (n= 181), intraventricular (n= 45), subdural (n= 13), or subarachnoid (n= 19). Noncontrast computed tomography scans were analyzed for each patient using Canon's
Stroke Solution ICH algorithm to determine which slices contained hemorrhage. The algorithm's ability to detect ICHs was assessed using sensitivity, specificity, positive predictive value, and negative predictive value.
