Multicenter Study Comparative Study
Antifibrinolytic agents reduce blood loss during pediatric vertebral column resection procedures.
Retrospective multicenter review. ⋯ EBL associated with VCR was highly variable and in many cases exceeded the patient's BV. AF agents were not routinely used and we had insufficient data to assess the efficacy of aminocaproic acid. Both aprotinin and TXA resulted in less EBL than when no AF was used; however, the effect of the reduction varied by site. Aprotinin has since been removed from the market. When normalized to patient size and levels excised, the use of TXA resulted in a reduction in intraoperative EBL.

Prospective study in a morbidly obese population after bariatric surgery. ⋯ Bariatric surgery, resulting in significant weight reduction, was associated with a significant decrease in low back and radicular pain as well as a marked increase in the L4-L5 intervertebral disc height. Reduction in body weight after bariatric surgery in morbidly obese patients is associated with a significant radiographical increase in the L4-L5 disc space height as well as a significant clinical improvement in axial back and radicular leg pain.

Comparative Study
Comparison of 3 reconstructive techniques in the surgical management of multilevel cervical spondylotic myelopathy.
A retrospective comparative study was performed in patients with 3-level cervical spondylotic myelopathy (CSM). ⋯ The HDF can be considered an effective and safe alternative procedure compared with ACDF in the treatment of the multilevel CSM, and ACCF should be the last option.

Case Reports
Development of a new technique for pedicle screw and Magerl screw insertion using a 3-dimensional image guide.
We developed a new technique for cervical pedicle screw and Magerl screw insertion using a 3-dimensional image guide. ⋯ This method employing the device using a 3-dimensional image guide seems to be easy and safe to use. The technique may improve the safety of pedicle screw and Magerl screw insertion even in difficult cases with narrow sclerotic pedicles.
