Intended Use

ZedView is intended to be used to assist qualified medical professionals to perform fast and effective pre-operative planning for various surgical procedures related to hip and knee by using 2D image data. The software is basically intended to be standalone, however some part of the software provides features for communicating with PACS servers to acquire the CT data of various patients or to upload planned projects, images or reports to the servers. The software primarily provides import and storage of CT images of various patients in DICOM or other formats. Also, it provides a means of 3D templating of implants and positioning of fixation devices by calculating surgical parameters in simulated environments and performing 3D measurements on each pre-operative patient data, using 2D image viewing and manipulations, 3D visualizations and various MPR (Multi-Planar Reconstruction) functions. The software also provides separate modules that support pre-operative planning of hip and knee arthroplasty for 2D digital X-rav images obtained with the EOS imaging system by providing quasi-3D templating, 3D measurement, etc. Besides the functional modules for artificial joint replacement surgeries, the software also provides a module that incorporates planning and evaluations for osteotomy (Curved Periacetabular Osteotomy etc.).

Device Story

ZedView is a software package for pre-operative planning of hip and knee surgeries. It accepts 2D DICOM CT slices or digital X-ray images (e.g., from EOS systems) as input. The software performs 3D reconstruction, multi-planar reconstruction (MPR), and 3D templating of implants and fixation devices. It allows clinicians to simulate surgical parameters, perform 3D measurements, and visualize bone models in post-operative positions. Used in clinical settings by medical professionals, the software communicates with PACS servers to acquire patient data and upload reports. The output—visualizations, measurements, and templated plans—assists surgeons in selecting appropriate implants and planning surgical approaches, potentially improving planning accuracy and surgical outcomes.

Clinical Evidence

Bench testing only. Verification and validation were performed using test image data and real-life patient data to confirm the software meets intended use and performance requirements.

Technological Characteristics

Software-based medical image management system. Operates on PC workstations (Windows). Supports DICOM standard. Features include 3D visualization, MPR, and 3D templating. Connectivity via PACS integration. No patient contact. Standalone software architecture.

Indications for Use

Indicated for pre-operative planning for hip and knee surgical procedures, including artificial joint replacement (3D implant templating) and osteotomy. For use by licensed, qualified healthcare professionals.

Regulatory Classification

Identification

OrthoviewTM provides the means of recording, storing and retrieving the templating process steps performed by the licensed medical professional when assessing the optimum prosthetic device for a particular patient.

Image format OrthoView uses digital X-ray image data, ZedView provides pre-operative planning from CT sliced image data. ## Discussion: The CT image data provides more relevant information than the X-ray images, thus offers a better and precise pre-operative planning, while the intended use and the indications for use remain the same. Besides, ZedView also contains separate operational modules (ZedHip-EOS, ZedKnee-EOS) for providing pre-operative planning for hip and knee using the digital X-ray (DX modality) images from the EOS imaging systems. ## 2. Templating system In contrast to the conventional 2D templating of OrthoView. ZedView provides CTbased 3D templating system. In addition to the template overlays in 2D cross-sectional images, the software allows user to place and register the 3D imported models of implants or fixation devices over the 3D reconstructed bone models and also provides 3D movement (translation, rotation) of the implants. In addition. ZedView offers visualization of bone models in various simulated post-operative positions and calculation of surgical parameters with respect to various coordinate systems. ## Discussion: The 3D templating system provides flexibility and extension of functionality by providing additional information (surgical parameters, range of motion analysis, etc.) for pre-operative planning than the 2D templating systems. Moreover, the 3D visualizations of bone and implant models help visualize elements that cannot be visualized in 2D, thus allowing for intuitive, effective and more accurate and precise planning. ## 3. Osteotomy operational module In addition to the joint replacement modules, the Osteotomy module in ZedView also offers simulations, measurements, surgical parameters calculations, etc. in 3D. ## Discussion: Similar to the discussion in section 2 above, the extra information and the 3D visualization of simulated bone models allow for intuitive, effective and more accurate and precise planning. ## Conclusion While there are some differences between ZedView and its predicates, these differences are minor and do not affect device substantial equivalence. It has the same basic operational principles and technical characteristics as its predicates and it functions in the same manner. Additionally, it has the indications for use and intended function and | Volume Number | Page Number | |---------------|-------------| | 8 | 8-7 | {7}------------------------------------------------ Image /page/7/Picture/0 description: The image contains the word "LEXI" in bold, black letters.
