Establishing a Staging System for Adjacent Segment Disease and Exploring Its Significance in Guiding Surgical Decisions: A Retrospective Study

open access: yesOrthopaedic Surgery, Volume 17, Issue 5, Page 1418-1432, May 2025.
Developed a staging system for adjacent segment disease based on degeneration characteristics. Verified the feasibility and reliability of stage‐guided surgical decision‐making through surgical data, radiological data, and follow‐up data. This staging system was closely correlated with intervertebral disc degeneration and disc height while also ...

Staged Lateral Lumbar Interbody Fusion Targeting Driver and Compensatory Structural Segments for Adult Degenerative Scoliosis: A Novel Strategy and Early Outcomes

open access: yesOrthopaedic Surgery, EarlyView.
Targeting driver and structural vertebrae via LLIF is an effective, minimally invasive strategy for ADS. It offers substantial deformity correction, symptom relief, and progressive postoperative self‐correction while significantly reducing surgical trauma compared to traditional long‐segment fusions.

Iliosacral Screw Fixation for Treating Sacral Fractures: A Modified Pedicle‐Guided Fixation Technique in Prone Position

open access: yesOrthopaedic Surgery, EarlyView.
Modified pedicle‐guided fixation technique for iliosacral screw placement in prone position reduces operation time and radiation exposure as conventional two‐dimensional fluoroscopy was enough to identify safe insertion corridors. Prone position is also advantageous when dealing with obese patients and concomitant spinal injuries.

A new concept for implant fixation: bone-to-bone biologic fixation [PDF]

open access: yesEuropean Cells & Materials, 2015
Many attempts have been made to reduce complications of bone implant, such as pedicle screw loosening. To address this problem, the authors suggest a new concept of bone-to-bone biologic fixation using recombinant human bone morphogenetic protein-2 ...

Is the postoperative pedicle screw position after dorsal instrumentation with or without intraoperative cone beam CT imaging worse in patients with obesity than in normal-weight patients?

open access: yesJournal of Orthopaedic Surgery and Research, 2022
Background Intraoperative cone beam CT (CBCT) imaging in dorsal instrumentation facilitates pedicle screw positioning. However, in patients with obesity, the benefit may be reduced due to artifacts that affect image quality. The purpose of this study was

Multidimensional Management of Degenerative Scoliosis: A Comprehensive Narrative Review Integrating Diagnostic Assessment, Surgical Decision‐Making, and Patient‐Centered Outcomes

open access: yesOrthopaedic Surgery, EarlyView.
The contemporary, multidimensional management pathway for de novo degenerative lumbar scoliosis, integrating quantitative diagnosis (coronal Cobb angle and Pfirrmann disk grading), multidimensional preoperative evaluation (CT Hounsfield Units, spinopelvic alignment, paraspinal muscle quality), stratified treatment (conservative care vs.
