Retrospective comparison of cortical bone trajectory and pedicle screw in lumbar fusion for patients over 80, including sagittal balance: a single-center study.
BMC Geriatr
January 2025
Department of Neurosurgery, Yonsei University College of Medicine, 50, Yonsei-Ro, Seodaemun-Gu, Seoul, 03722, Republic of Korea.
Background: Comparative studies of posterior lumbar interbody fusion with cortical bone trajectory and pedicle screw in older patients, particularly in those aged ≥ 80 years, are rare. This study aimed to retrospectively analyze the clinical and surgical outcomes following posterior lumbar interbody fusion with pedicle screw fixation compared to cortical bone trajectory in patients aged ≥ 80 years with degenerative lumbar spine disease.
Methods: We included 68 patients aged ≥ 80 years who underwent degenerative lumbar spinal surgery at our spine center between January 2011 and December 2020.
Minimally invasive prone lateral retropleural or retroperitoneal antepsoas approach spinal surgery using the rotatable radiolucent Jackson table.

Department of Orthopedic Surgery, Chung Shan Hospital, Taipei, Taiwan.
Background: Prone lateral spinal surgery for simultaneous lateral and posterior approaches has recently been proposed to facilitate surgical room efficiency. The purpose of this study is to evaluate the feasibility and outcomes of minimally invasive prone lateral spinal surgery using a rotatable radiolucent Jackson table.
Methods: From July 2021 to June 2023, a consecutive series of patients who received minimally invasive prone lateral spinal surgery for various etiologies by the same surgical team were reviewed.
Robot-assisted minimally invasive transforaminal interbody fusion: a complete workflow pilot feasibility study.
J Spine Surg
December 2024
Department of Orthopaedic Surgery, Changi General Hospital, Singapore, Singapore.
Background: Robotic-assisted spinal surgery has reportedly improved the accuracy of instrumentation with smaller incisions, improving surgical outcomes and reducing hospital stay. However, robot-assisted spine surgery has thus far been confined to placement of pedicle screw instrumentation only. This pilot study aims to explore the feasibility of utilizing the Mazor™ X Stealth Edition (Medtronic, Sofamor Danek USA), robotic-arm platform in the minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) procedure inclusive of interbody cage placement, in our institution.

Department of Orthopedic Surgery, Toyama Prefectural Central Hospital, Toyama City, Japan.
Background: There is no consensus on the association between final local kyphosis and residual back pain (RBP) after traumatic vertebral fracture. The aim of this study was to investigate whether there is an association between the final local kyphosis angle and RBP in patients with traumatic vertebral fractures at the thoracolumbar junction who underwent single posterior surgery with percutaneous pedicle screws and implant removal after fracture healing. A second goal was to determine the optimal cut-off value for the final local kyphosis angle with and without RBP.

College of Medicine, Mohammed Bin Rashid University of Medicine and Health Sciences, Dubai Health, Dubai, UAE.
The first cervical vertebra (C1) is atypical in shape and bears a complex relationship with important neurovascular structures such as the vertebral artery and cervical spinal cord which are at risk of injury during misplaced screw fixation of C1. Placement of screws into the lateral mass of C1 vertebra is performed for stabilization of the craniovertebral junction. The objective of this study was to describe ideal screw dimensions, precise entry points, safe bony corridors, and ideal trajectories for placement of lateral mass screws in the Emirati population.
