Study design: Retrospective comparison based on the degree of pelvic obliquity (PO). Purpose: To assess the controversial indications for and limitations of ending the instrumentation for posterior spinal fusion (PSF)…
Background context: Manual contouring of spinal rods is often required intraoperatively for proper alignment of the rods within the pedicle screw heads. Residual misalignments are frequently reduced by using dedicated…
Study objective: To evaluate the effectiveness and safety of S-ketamine for pain relief and analgesic consumption in surgical patients. Design: Systematic review and meta-analysis of randomized controlled trials (RCTs). Setting:…
Objective: In the future, payers may not cover unplanned 90-day emergency room (ER) visits or readmissions after elective lumbar spine surgery. Prior studies using large administrative databases lack granularity and/or…
Purpose: Adjacent segment disease (ASD) constitutes a long-term complication of instrumented spinal fusion. Aim of this study is to analyze the utilization of percutaneous transforaminal endoscopic discectomy (PTED) for the…
Background: Cortical bone trajectory (CBT) technique has a theoretical benefit for patients with osteoporosis, and leads to reduce screw loosening. However, there are no reports of complications and outcomes of…
