A sagittal whole spine view should be added as a scout view when patients obtain lumbar MRI to standardize the vertebral numbering technique. To date, there has been no other method for accurate numeration of a transitional vertebral segment, other than counting caudally from C2.

Introduction: The LigaSure system has been successfully used in thoracic and abdominal surgery. However, to date, its use in the resection of sarcomas has not been systematically studied. We aimed to determine whether the use of the LigaSure system reduces blood loss and blood transfusion volumes in sarcoma surgery. Methods: One hundred forty-two consecutive patients who underwent sarcoma surgeries between July 2010 and October 2016 were included. Conventional electrocautery alone (n = 91) and with LigaSure (n = 51) were compared. Case-matched samples (n = 46) from each group were additionally compared. Results: The use of the LigaSure system resulted in a significant decrease in mean intraoperative blood loss (P = 0.02) and blood transfusion volume (P = 0.04). Likewise, a significant decrease in both mean and median intraoperative blood loss (P = 0.003; P , 0.0001) was seen with LigaSure in the case-matched analysis. In the soft-tissue sarcoma subgroup, a significant decrease was observed in mean hemoglobin reduction (P = 0.03) and mean intraoperative blood loss with LigaSure (P = 0.04). No adverse perioperative complications attributed to the LigaSure system were identified. Conclusions: The LigaSure vessel sealing and dividing system is a safe and effective hemostatic tool for deep dissection in bone and softtissue sarcoma surgery.

Mini We summarized the 10-year outcomes of Spine Patient Outcomes Research Trial for intervertebral disc herniation through a systematic review. The observational cohort 2-year analysis and the as-treated analysis of the randomized control trial at 4 and 8 years showed statistically greater improvements in those patients who were treated surgically. Study Design. We performed a comprehensive search of Pubmed, MEDLINE, and EMBASE for English-language studies of all levels of evidence pertaining to SPORT, in accordance with Preferred Reported Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Objective. We aim to summarize the 10-year clinical outcomes of SPORT and its numerous follow-up studies for intervertebral disc herniation. Summary of Background Data. The Spine Patient Outcomes Research Trial (SPORT) was a landmark study. SPORT compared surgical and nonoperative management of the three most common spinal pathologies. Methods. Keywords utilized included: SPORT, spine patient outcomes research trial, disc herniation, and surgical outcomes. Results. The observational cohort analysis revealed statically greater improvement in primary outcomes at 3 months and 2 years in patients who had surgery, while analysis of the randomized control trial cohort failed to show a significant difference based on the intent-to-treat principle due to significant patient crossover. However, 4 year and 8 year as-treated analysis showed statistically greater improvements in those patients who were treated surgically. SPORT's subgroup analysis evaluated important factors when considering the treatment of IDH, including patient characteristics, level of herniation, duration of symptoms, recurrence of pain, presence of retrolistheiss, patient functional status, effects of previous treatment with epidural steroid injections and opioid medication, outcomes after incidental durotomy, MRI reader reliability, reoperation rates, and risk factors for reoperation. The clinical impact of SPORT was also investigated and included comparison of SPORT patients to NSQIP patients to determine generalizability, outcome differences in SPORT's surgical center sites, patient preferences, patient expectations, level of education, and effects of watching an evidence-based video. Conclusion. Ten years after its inception, SPORT has made strides in standardization and optimization of treatment for spinal pathologies. SPORT has provided clinicians with insight about outcomes of surgical and nonoperative treatment of IDH. Results showed significantly greater improvements in patients treated surgically.
