Comparative Study Clinical TrialQuantitative volumetry of cement leakage in viscosity-controlled vertebroplasty.
This study was designed as a cohort study comparing a prospective sample to a historic control group. ⋯ The use of viscosity-controlled vertebroplasty led to a decrease in the leakage rate from 58.3% to 42.1%. Leakage into the basivertebral vein with the risk of compression of nerval structures was reduced to almost 50% when viscosimetry was performed. It revealed to be a helpful tool for more unexperienced surgeons to assess the appropriate viscosity for vertebroplasty.

Comparative StudyHemostasis with a bipolar sealer during surgical correction of adolescent idiopathic scoliosis.
Retrospective before-after comparison study. ⋯ These findings suggest that the Aquamantys 2.3 bipolar sealer effectively supports hemostasis and reduces the need for transfusions during surgical correction of AIS.

Comparative StudyAssessment of pedicle screw placement accuracy, procedure time, and radiation exposure using a miniature robotic guidance system.
Controlled, cadaveric implantation trial. ⋯ The advantages associated with a robotic guidance system may make the surgeon more at ease about offering minimally invasive or percutaneous surgical options to patients and more comfortable about implementing pedicle-based fixation in general. This advanced technology may also allow inclusion of patients with complicated anatomic deformities, who are often excluded from pedicle screw-based surgery options.

Case ReportsEfficacy of novel minimally invasive surgery using spinal microendoscope for treating extraforaminal stenosis at the lumbosacral junction.
A retrospective case study of the spinal microendoscopic surgery for the treatment of extraforaminal stenosis at the lumbosacral junction. ⋯ The spinal microendoscopic surgery demonstrated efficacy for treating extraforaminal stenosis at the lumbosacral junction where the lesion is difficult to be exposed. Quick and easy access along with minimal damage to the back muscles and bony structures could be accomplished using the property of its oblique view and angled surgical equipments. This procedure has produced long-lasting favorable outcomes and high patient satisfaction. Novel minimally invasive surgery may replace conventional open methods.

Lumbarized sacrum as a relative contraindication for lateral transpsoas interbody fusion at L5-6.
Retrospective review. ⋯ Treating the L5-6 level using a lateral transpsoas approach in individuals with lumbarized sacra can be challenging due to anatomy more similar to the L5-S1 level in normal patients. Preoperative planning using axial MRI and intraoperative adherence to advanced neuromonitoring can aid in identifying and avoiding injury in these rare patients.
