Nonlaminotomy bilateral decompression: a novel approach in biportal endoscopic spine surgery for spinal stenosis.

Biportal endoscopic spine surgery (BESS) is an emerging technique for lumbar spinal stenosis. Previous BESS techniques involve partial osteotomy for access to spinal canal such as partial laminotomy, partial facetectomy, and other forms to access the spinal canal for decompression. However, approaches that include osteotomy can cause bone bleeding intraoperatively, leading to obscured vision, and may be at risk of postoperative facet arthritis and segmental instability due to damage to the posterior stability structure.

Radiological Spinopelvic Parameters Can Be Risk Factors for Early Total Hip Replacement After Spine Fusion.

Background: Interest in the correlation between the spinopelvic complex and its radiographic parameters in early total hip arthroplasty has been increasing. This study investigated whether radiological spinopelvic parameters are risk factors for early total hip replacement (THR) within 1 year of spinal fusion surgery. The primary research question focused on identifying specific spinopelvic changes that may lead to early THR.

Sacroiliac Joint Degeneration After Lumbar or Lumbosacral Fusion Surgery-A Comparative Study of the Number of Fused Segments and Sacral Fusion.

Objective: In this study, we aimed to investigate whether multi-segment fusion or fusion-to-sacrum increases sacroiliac joint (SIJ) pathology compared with single-segment fusion or a non-fused sacrum.

Methods: This study included 116 patients who underwent lumbar or lumbosacral fusion and were followed up for 2 years. The patients were classified into single-segment fusion (n = 46) and multi-segment fusion (more than two levels, n = 70) groups and then reclassified into the non-fused sacrum (n = 68) and fusion-to-sacrum groups (n = 48).

Effect of saline irrigation temperature difference on postoperative acute pain and hypothermia during biportal endoscopic spine surgery.

Study Design: Retrospective observational study.

Objective: To determine the proximity between screw and endplate of the upper instrumented vertebra (UIV) using a cortical bone trajectory (CBT) screw as a predictive factor for radiographic adjacent segment degeneration (ASD) in patients surgically treated with transforaminal lumbar interbody fusion (TLIF) with CBT screws (CBT-TLIF) with lumbar spinal stenosis.

Summary Of Background Data: The risk factors for radiographic ASD after CBT-TLIF remain unknown.

Association of Functional Gastrointestinal Disorders with Adolescent Idiopathic Scoliosis.

Numerous adolescents diagnosed with adolescent idiopathic scoliosis (AIS) often manifest symptoms indicative of functional gastrointestinal disorders (FGIDs). However, the precise connection between FGIDs and AIS remains unclear. The study involved adolescents drawn from sample datasets provided by the Korean Health Insurance Review and Assessment Service spanning from 2012 to 2016, with a median dataset size of 1,446,632 patients.

Effectiveness of Toothbrushing Technique for Biofilm Removal and Postoperative Infection Control after Spinal Fusion Surgery: A Retrospective Study.

This retrospective study was designed to investigate the effectiveness of using a toothbrush, which is commonly used in our daily life, for biofilm removal and infection control in the treatment of spinal infections occurring after spinal fusion surgery. Currently, a biofilm is thought to form on the surface of the metal inserted during spine fusion surgery. We aim to determine the differences in clinical outcomes between using and not using a toothbrush to remove biofilm while performing conventional drainage, curettage, and debridement.
