Mini‐Open Versus Open Transforaminal Lumbar Interbody Fusion in Patients Aged ≥ 75 Years: Perioperative Surgical Burden and Clinical Outcomes

Orthopaedic Surgery, Volume 18, Issue 10, Page 2090-2100, October 2026.
In 172 patients aged ≥ 75 years undergoing TLIF, mini‐open TLIF (MO‐TLIF) reduced perioperative burden (shorter operative time, less blood loss, lower POD3 CK) and enabled faster early pain/function recovery versus open TLIF, while 3–6 month PROMs and 12‐month fusion and satisfaction were comparable.

Robot assisted navigated drilling for percutaneous pedicle screw placement: A preliminary animal study

, 2015
Background: There is much more radiation exposure to the surgeons during minimally invasive pedicle screws placement. In order to ease the surgeon's hand-eye coordination and to reduce the iatrogenic radiation injury to the surgeons, a robot assisted

Headless Compression Screw Fixation Alone for Lunate Coronal Fractures in Kienböck Disease

Orthopaedic Surgery, Volume 18, Issue 10, Page 2224-2229, October 2026.
The optimal management of Kienböck disease with lunate coronal fractures remains controversial. Previous studies advocated excision of the fractured lunate followed by scaphotrapeziotrapezoidal (STT) fusion or proximal row carpectomy. In this study, headless compression screw alone achieved fracture healing and satisfactory clinical outcomes in ...

Comparison of short-segment monoaxial and polyaxial pedicle screw fixation combined with intermediate screws in traumatic thoracolumbar fractures: a finite element study and clinical radiographic review

Clinics
OBJECTIVES: No studies have compared monoaxial and polyaxial pedicle screws with regard to the von Mises stress of the instrumentation, intradiscal pressures of the adjacent segment and adjacent segment degeneration.

Effect of pedicle screw augmentation with a self-curing elastomeric material under cranio-caudal cyclic loading—a cadaveric biomechanical study

Journal of Orthopaedic Surgery and Research, 2018
Background Pedicle screws can be augmented with polymethylmethacrylate (PMMA) cement through cannulated and fenestrated pedicle screws to improve screw anchorage. To overcome the drawbacks of PMMA, a modified augmentation technique applying a self-curing

Global Alignment and Proportion (GAP) Score in Predicting Mechanical Complications After Long‐Segment Fixation for Chinese Geriatric Patients With Adult Degenerative Scoliosis: A Mid‐Term Comparative Study

Orthopaedic Surgery, Volume 18, Issue 10, Page 2195-2204, October 2026.
In our study, we found that the GAP score could effectively predict the risk of mechanical complications after long‐segment fixation surgery in geriatric ADS patients. ABSTRACT Objectives The predictive value of the global alignment and proportion (GAP) score in the Chinese geriatric population, which has unique demographic and degenerative ...

Dorsal C1–2 Spinal Cord Compression After Reduction of Atlantoaxial Posterior Dislocation Associated With Os Odontoideum: A Case Report and Literature Review

Orthopaedic Surgery, Volume 18, Issue 10, Page 2269-2275, October 2026.
Successful reduction of os odontoideum‐associated atlantoaxial posterior dislocation may not always guarantee adequate C1–2 canal space. In patients with congenital atlas hypoplasia or posterior arch osteophytes, postreduction dorsal cord compression should be anticipated, and C1 posterior arch decompression may be required to prevent neurological ...

Technical aspects of rod-insertion forceps (persuader) application in reducing construct failure after lumbar spine fusion surgery: a biomechanical cadaveric study in Germany [PDF]

Asian Spine Journal
Study Design A prospective experimental study. Purpose This biomechanical in vitro study aimed to examine the extent to which the use of a rod persuader (RP) leads to additional mechanical stress on the screw–rod system and determine its influence on the
