Randomized Controlled Trial Multicenter Study
Superion® InterSpinous Spacer Treatment of Moderate Spinal Stenosis: 4-year Results.
To determine 4-year clinical outcomes in patients with moderate lumbar spinal stenosis treated with minimally invasive stand-alone interspinous process decompression using the Superion device. ⋯ Minimally invasive implantation of the Superion device provides long-term, durable relief of symptoms of intermittent neurogenic claudication for patients with moderate lumbar spinal stenosis.

Preoperative Planning of Lateral Entry Point is Necessary in Percutaneous Lumbar 5th Vertebroplasty.
To compare treatment outcomes and complications between the computer-assisted preoperative planning of lateral entry approach and the traditional approach for L5 percutaneous vertebroplasty. ⋯ Owing to the hemispherical morphology and convergent pedicle axis of the L5 vertebrae, a more lateral skin entry point and convergent angle of the puncture needle should be emphasized to reach the optimal point according to the preoperative assessment. The approach involving computer-assisted preoperative planning of the lateral entry point was associated with a higher rate of bilateral cement infiltration with fewer complications.

Accuracy of Varioguide frameless stereotactic system against Frame based stereotaxy: Prospective randomized single-centre study.
Frameless stereotactic brain biopsy systems are widely used today. VarioGuide (VG) is a relatively novel frameless system. Its accuracy was studied in a laboratory setting but has not yet been studied in the clinical setting. The purpose of this study was to determine its accuracy and diagnostic yield and to compare this with frame-based (FB) stereotaxy. ⋯ The VG system proved to be comparable in terms of the trajectory accuracy, rate of complications and diagnostic yield compared with the "gold standard" represented by the traditional FB stereotaxy for patients undergoing brain biopsy. VG is also better accepted by patients.
