Minimally invasive cervical pedicle screw fixation via the posterolateral approach for metastatic cervical spinal tumors

Spine Surgery and Related Research, 2017
Background: To avoid lateral misplacement of midcervical pedicle screws, we developed a method for Minimally Invasive Cervical Pedicle Screw (MICEPS) fixation via a posterolateral approach.

Evaluation of Curve Flexibility Using Scoliotic Spines Generated From a Generic Spine Model

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 9, September 2026.
This study presents a modelling procedure to evaluate curve flexibility in adolescent idiopathic scoliosis. Models were generated from a previously assessed adolescent spine model, with patient radiographs used to estimate traction forces. Sequential spinal release simulations were conducted.

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

The Bony Density of the Pedicle Plays a More Significant Role in the Screw Anchorage Ability Than Other Regions of the Screw Trajectory

Orthopaedic Surgery
Objective Osteoporosis is a crucial risk factor for screw loosening. Our studies indicate that the bone mineral density (BMD) in the screw trajectory is a better predictor of screw loosening than the BMD of the lumbar spine or the screw insertion ...

The Effect of Single Level and Multilevel Cervical Fusion on Adjacent Segment Motion: A Biomechanical Analysis

JOR SPINE, Volume 9, Issue 3, September 2026.
ABSTRACT Background Cervical arthrodesis is a common surgical technique utilized to treat many cervical spinal pathologies. The risk of re‐operation due to symptomatic adjacent segment disease (ASD) remains steady, and the cause of ASD, whether rigid fixation or disease progression, remains unknown.

A Novel Gelatin Hydrogel‐Based Drug‐Delivery System Promotes Antimicrobial Efficacy in a Pyogenic Spondylodiscitis Rat Model

JOR SPINE, Volume 9, Issue 3, September 2026.
ABSTRACT Background Spondylodiscitis/spondylitis is an intractable disease requiring long‐term intravenous antibiotics administration. However, drug delivery is greatly restricted because of the avascular nature in the intervertebral disc, which not only delays recovery but increases antimicrobial resistance and osteomyelitis. The purpose of this study

Are Ceramic Cages an Option for Lumbar Interbody Fusion? A Comparative Biomechanical Numerical Study

JOR SPINE, Volume 9, Issue 3, September 2026.
ABSTRACT Background The treatment of severe disc pathologies through lumbar interbody fusion (LIF) involves the insertion of an interbody cage into the degenerated disc space, together with a supporting fixation system. Conventional cage materials, such as Ti6Al4V and PEEK, present several limitations, most notably their non‐biodegradability ...

The Effects of Remote Ischemic Preconditioning on the Inflammatory Cytokine Response to Free Flap Head and Neck Reconstruction: A Randomized Controlled Trial

Microsurgery, Volume 46, Issue 6, September 2026.
ABSTRACT Introduction Ischemia–reperfusion injury due to vascular pedicle occlusion is one of the most common causes of free flap failure in head and neck cancer reconstruction. Remote ischemic preconditioning (RIPC) has been proposed as an experimental, non‐invasive intervention to attenuate flap ischemia–reperfusion injury; however, the tissue ...
