C2 pars interarticularis length on the side of high-riding vertebral artery with implications for pars screw insertion.
Scientific reports
May 28, 2025
C2 pars interarticularis length (C2PIL) required for pars screws has not been thoroughly studied in subjects with high-riding vertebral artery (HRVA). We aimed to measure C2PIL specifically on the sides with HRVA, define short pars, optimal pars scre...
Optimization of primary screw stability in Trabecular bone using neural network-based models.
Computer methods and programs in biomedicine
Mar 10, 2025
BACKGROUND AND OBJECTIVE: Screw implant stability in bone is crucial to the success of many orthopaedic procedures, yet the relationship between screw design parameters and specific bone characteristics remains underexplored. This study aims to optim...
Assessing screw length impact on bone strain in proximal humerus fracture fixation via surrogate modelling.
International journal for numerical methods in biomedical engineering
Jun 12, 2024
A high failure rate is associated with fracture plates in proximal humerus fractures. The causes of failure remain unclear due to the complexity of the problem including the number and position of the screws, their length and orientation in the space...
Robot-assisted Temporary Hemiepiphysiodesis With Eight-plates for Lower Extremity Deformities in Children.
Journal of pediatric orthopedics
Feb 5, 2024
PURPOSE: This study was performed to compare the radiographic results of robot-assisted and traditional methods of treating lower extremity deformities (LEDs).
Impact of optical navigation variables on the accuracy of robot-assisted surgery: a study of the TIANJI Robot system.
Journal of robotic surgery
Jan 17, 2024
This study aims to explore factors related to optical navigation that interfere with the accuracy of robot-assisted surgery, specifically focusing on the TIANJI Robot system. A measurement model was created to assess the accuracy of the TIANJI Robot ...
Robot-assisted close reduction with double screw fixation for the coracoid-process base fracture: A case report.
Asian journal of surgery
Dec 29, 2023
Minimally invasive percutaneous screw internal fixation under robot navigation for the treatment of a hamate bone fracture.
BMC musculoskeletal disorders
Dec 1, 2023
PURPOSE: Hamate fractures are rare fractures of the wrist and there is still no consensus on the optimal treatment for these fractures, especially hook of hamate fractures. Herein, the authors present a case study of a series of patients who were tre...
Perception of Robotics and Navigation by Spine Fellows and Early Attendings: The Impact of These Technologies on Their Training and Practice.
World neurosurgery
Oct 14, 2023
BACKGROUND: There is scant data on the role that robotics and navigation play in spine surgery training and practice of early attendings. This study aimed to assess the impact of navigation and robotics on spine surgery training and practice.
A Cadaveric Feasibility Study of an Automatic Multi-Degrees of Freedom Surgical Robot for Percutaneous Scaphoid Guide Pin Insertion.
The journal of hand surgery Asian-Pacific volume
Sep 25, 2023
Percutaneous fixation of scaphoid fractures need accurate guide pin insertion. The emergence of computer-assisted navigation and robotic surgery may provide a promising solution to this problem. This study presents the development of an automatic m...
Analysis of Friction Noise Mechanism in Lead Screw System of Autonomous Vehicle Seats and Dynamic Instability Prediction Based on Deep Neural Network.
Sensors (Basel, Switzerland)
Jul 5, 2023
This study investigated the squeal mechanism induced by friction in a lead screw system. The dynamic instability in the friction noise model of the lead screw was derived through a complex eigenvalue analysis via a finite element model. A two degree ...
