2021年11月2日 · In this study, a new percutaneous multi-function pedicle locator was designed for personalized three-dimensional positioning of a pedicle in minimally invasive spine surgery (MISS) without...

3 小时之前 · Objective To compare the accuracy and safety of implanting cervical pedicle screws (CPS) between orthopedic surgical robot-assisted technique and traditional fluoroscopy-assisted free-hand technique. Methods Retrospective analysis of 95 patients treated with posterior cervical spinal surgery using either Tianji orthopedic surgical robot-assisted or traditional fluoroscopy-assisted free-hand ...

3 天之前 · Additionally, lateral mass instrumentation generally involves limited screw fixation in comparison to the placement of pedicle screws 6, 7. With the aim of avoiding the need for an invasive approach, here we performed a cadaver study to verify the accuracy of image-guided percutaneous pedicle screw instrumentation at the cervical spine.

2025年1月19日 · Background: Pedicle screw placement in spine surgery is a complex and delicate procedure that requires precise and accurate placement of pedicle screws. This technical note describes the steps involved in performing robotic assistance pedicle screw insertion in thoracolumbar spine surgery using the ExcelsiusGPS platform.

This study involved 70 patients with moderate idiopathic scoliosis who had undergone deformity correction surgery between 2018 and 2021. Two spine surgeons used three techniques (preoperative computed tomography scan [CTS], visual inspection‐X‐freehand [XFH], and intraoperative detection [ID] of anatomical landmarks) to locate pedicle screws.

2025年1月21日 · A study at Hospital for Special Surgery (HSS) comparing robotic-assisted navigation to the use of augmented reality in spine surgery found that both techniques demonstrate excellent accuracy and safety for pedicle screw placement. The research was published online ahead of print by the journal Spine.

ercially available pedicle screws used in spinal fusion surgeries, and data augmentation was used to expand 300 images. The model was trained, validated, and ld detect the locations of the pedicle screws in the surgical scene as well as their direction angles

2020年7月1日 · We designed a localization system with six parameters (starting point height [SP-H], starting point length [SP-L], transverse section angle, sagittal section angle [SSA], pedicle width [W] and height [H]) based on preoperative computed tomography reconstruction and combined it with the Roussouly classification to guide lumbar spine pedicle screw...

1 天前 · The field of robot-assisted orthopedic surgery is witnessing rapid expansion [1, 2]. Among these, the placement of pedicle screws during spinal fusion stands out as a critical step for ensuring spinal stability [3].

In this study, a new percutaneous multi-function pedicle locator was designed for personalized three-dimensional positioning of a pedicle in minimally invasive spine surgery (MISS) without computer-assisted navigation technology. The proposed locator was used in a number of patients during MISS, and its advantages were analyzed.
