Thoracic Pedicle Screw Placement Guide Plate Produced by Three-Dimensional (3-D) Laser Printing
BACKGROUND The aim of this study was to evaluate the accuracy and feasibility of an individualized thoracic pedicle screw placement guide plate produced by 3-D laser printing. MATERIAL AND METHODS Thoracic pedicle samples of 3 adult cadavers were randomly assigned for 3-D CT scans. The 3-D thoracic models were established by using medical Mimics software, and a screw path was designed with scan...
متن کاملUpper lumbar pedicle screw insertion using three-dimensional fluoroscopy navigation: assessment of clinical accuracy.
We used a navigation system to insert 128 pedicle screws into 69 vertebrae (L1 to L3) of 49 consecutive patients. We assessed the pedicle isthmic width and the permission angle for pedicle screw insertion. The permission angle is the angle defined by the greatest medial and lateral trajectories allowable when placing the screw through the center of the pedicle. The rate of narrow-width pedicles...
متن کاملTreatment for odontoid fracture with C1 lateral mass and C2 pedicle screws using intraoperative orbic-3-dimensional navigation
Objective: To assess the technical advantages of intraoperative orbic-3-dimensional navigation in the treatment of odontoid fractures. Material and methods: Twelve male patients with type II or rostral type III odontoid fractures were treated with posterior C1LM-C2P screws fixation using the orbic-3D fluoroscopic navigation. The follow-up period ranged from 12 to 24 months with a mean of 19.2 m...
متن کاملMinimally Invasive Pedicle Screw Fixation Using Intraoperative 3-dimensional Fluoroscopy-based Navigation (CAMISS Technique) for Hangman Fracture.
STUDY DESIGN Retrospective comparative cohort series. OBJECTIVE To evaluate the accuracy and feasibility of minimally invasive surgical (MIS) techniques incorporating with intraoperative 3-dimensional fluoroscopy-based navigation (ITFN) for treating Hangman fracture. SUMMARY OF BACKGROUND DATA MIS screw fixation for Hangman fracture can decrease iatrogenic soft-tissue injury, but increase t...
متن کاملDimensional 3 - D Printing in Organ Transplantation
An insufficient supply of organs for transplant is an ever present obstacle for transplant medicine. A long term resolution of these problems is being sought by developing ways to engineer live organs from a person’s own cells. Previous tissue manufacturing approaches involved seeding either adult or stem cells onto various 3D scaffolds, with subsequent cell proliferation and differentiation in...
