Reduction Planning Using ZedTrauma for Long Bone Shaft Fractures of the Extremities
Objective
In comminuted long bone shaft fractures of the extremities due to occupational injury, examine the bone fragment reduction procedure preoperatively.
Subjects
- Cases: 6 cases
- Fracture site: humeral shaft (3 cases), femoral shaft (3 cases)
- Injury type: Comminuted fracture
Evaluation Items
- Bone fragment reduction procedure
- Plate selection and screw insertion trajectory
- Agreement between the preoperative plan and intraoperative reduction
Results
Understanding the complex fragment alignment preoperatively facilitated surgical planning.
Discussion
Preoperative 3D visualization of the complex fragment alignment is expected to reduce surgical time and improve reduction accuracy.
ZedTrauma
Overview
A module that supports reduction simulation of bone fragments and plate selection for open reduction and internal fixation of fractures.
ZedTrauma is for supporting planning bone fracture and trauma treatment of pelvic ring, acetabular, proximal and distal femur, and proximal and distal radius utilizing CT images.
For proximal femur fracture treatment, component positioning simulation with plate, nail and wire is available.
Features
- Intuitive operation on the 3D model
- Templates based on extensive installation experience
- Report output for sharing surgical records
Database of Patient Records
User can import CT data in DICOM format into a database application.
Patient information (such as name, sex, date of birth, etc.) can be managed uniformly.
Furthermore, this database application can be used as simple DICOM viewer to view the images in axial, sagittal and coronal views.

Bone Cut and Repositioning Simulation
User can separate 3D bone model into parts by specifying bone cut path, and simulate rotation and translation of the separated parts for manual repositioning simulation.
Component Positioning Simulation
User can simulate component positioning on repositioned bone model with checking axial, sagittal and coronal sections and 3D bone models.
2D and 3D Measurement
Not only measuring distance between 2 points or angle on 2D slice images, but also direct distance and angle on 3D bone model are available as 3D measurement function.
