Comparative StudyComparison of disc and vertebral wedging between patients with adolescent idiopathic scoliosis and Chiari malformation-associated scoliosis.
A comparative study. ⋯ The relative wedging of intervertebral disc and vertebrae with AIS patients is similar to that of scoliosis with known cause (CMS). The wedging of discs and vertebrae in AIS patients may be an adaptive change secondary to some extravertebral factors.

Surgical outcome of percutaneous endoscopic interlaminar lumbar diskectomy for recurrent disk herniation after open diskectomy.
Technical report. ⋯ PEID with dissection of the scar tissue from the medial facet joint rather than from the neural tissue may be an effective alternative surgical method for recurrent disk herniation.

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.
