Randomized Controlled Trial
A New Pilot Hole Preparation System for Percutaneous Pedicle Screw Placement - A Randomized Controlled Study.
A randomized controlled study. ⋯ The new pilot hole preparation system has shown significant reductions in the time of pilot hole preparation, time of screw placement, and radiation exposure, and has good clinical application value.
-
Cohort study. ⋯ Overall, there were 37 (33.3%) patients with CP who had a major complication within 30 days after spinal surgery. Lower SAS, with the 0 to 4 group being the cutoff, were associated with significantly higher complication rates than higher SAS groups.

Observational Study
Intra-Operative Hypotension is an Important Modifiable Risk Factor for Major Complications in Spinal Fusion Surgery.
Retrospective observational cohort. ⋯ III.
-
Retrospective review of prospectively collected data. ⋯ Patients are expected to improve up to 6 months after MIS TLIF. Back pain and leg pain improve up to 3 months and disability and physical function improve up to 6 months. Beyond these timepoints, the trends in improvement tend to reach a plateau. 80% of patients feel better compared to preoperative by 3 months after surgery.

Retrospective review of a prospectively collected single-center adolescent idiopathic scoliosis (AIS) database. ⋯ The mean lumbar Cobb angle (19°) and percentage of patients with a lumbar Cobb angle > 35° (10%) were similar for CSing and CBil groups at the latest follow-up. Thus, performing a bilateral VBT did not significantly improve the postoperative lumbar curve magnitude compared with thoracic-only VBT (CSing) in our cohort. There was a non-significant difference in revision rates for A/B vs. C groups (18% vs. 28%), and CSing vs. CBil (20% vs. 40%). Revision rates were threefold higher in all patients with preoperative open TRC.
